tun.ko for 2.1 ROMs..? Need for Cisco VPN

Hey, I have been looking forward to the 2.1 update for our Heros because I thought it was going to finally give us simple VPN access... *to Cisco concentrators*. Unfortunately, it only gives us IPSec/L2TP PSK or CRT... whereas I need a pure IPSec client that supports Group Authentication in order to connect to my corporate VPN.
So, I, and I am sure many others, need to revert back to the Get-A-Robot-VPNC client to connect to our corporate networks, but apparently do not have a correct tun.ko module. Trying to insmod a tun.ko module, I get "invalid format" or "failed executable" - So, can someone provide a tun.ko that we can use, or explain how to get one installed in these new 2.1 ROMs?
I am currently using the ZenHero 2.1 ROM
Thanks! Once I get VPN access again, the Hero will really be something pretty damn awesome again.

Or, does anyone know of any VPN clients coming down the pipe for Android? or any other projects in development?
I heard Shew Soft was coming out with a mobile variant... not sure if it'll be on Android though..

I have no use for it or way to try it, but I did find vpn connections in the market when searching for something else and remembered this thread. It said on the comments though to go to the site for the latest version. http://code.google.com/p/get-a-robot-vpnc/
actually, a search for vpn in the market turned up a few options. Take a look, I don't know exactly what you need.

I have been trying multiple ways. I even tried the tun.ko. I have not been successful but I would like to hear if anyone is successful.

Unfortunately, none support, what I think to be the most popular VPN type, from a corporate stand-point: pure IPSec that supports Group Authentication. Most in the market are just for VPNC.
Thanks for your post though.

Yes the android app is lacking.
I have a Cisco concentrator working with MY phone. I just dumped all Group based auth. We wanted a device that would work with 99.999% of devices on the market and our little Asa-5505 does the trick.
You should be able to configure policies on the cisco to handle either clients, that is really your or your admins choice.
Otherwise the stock android vpn client MY only complaint is it will NOT let me vpn over mobile network.. only wifi. Kinda pointless if I have wifi I would use my laptop to vpn to work. WTF?

Sprint is the problem

I realize this post has been sitting here for a while, but I thought this might help some others who may run into similar issues. At my work, we have all Cisco equipment and have a Cisco ASA configured with PSK mobile VPN. We are having basically no luck getting in using Sprint-connected devices (Sprint EVO 4G) on anything but Wifi. I CAN, however, connect just fine on my Samsung Captivate over AT&T 3G signal using the same built-in android VPN client. We've gone the rounds with the Sprint Engineers on this and they have nothing they can pinpoint that is causing this outage. I would really like for either Cisco or Sprint to come up with a good explanation as it shouldn't matter if you're on Wifi or 3G, it should work either way. The point is that it works on AT&T for us, but not Sprint, as far as 3G/4G data connection is concerned.

VPN works fine in Wi-Fi but not with 3G

I'm hopeless here. I have a paid VPN service, and it works perfectly with my PC, with my mobile on Wi-Fi and with my friend's mobile also on 3G, but not on mine. For sure there's something wrong with my device. I tried hard reset, different ROMS and all different servers and settings.
It does connect to the VPN and it keeps up the connection, but internet just doesn't work. Anyone have any idea why this is happening? I tried to search other threads about this, but no success.
Thanks

Same here ... I search but nothing ... I'm on Ressurection Remix 3.1.3 with Kernel cm 10.1... VPN in 3G don't work

Have you tried the app Go to my p.c. app?

vpn thrue 3g and mobile connection
hi
reason, routing.
1. you have to setup your vpn connection to route any data between your vnp-connection.
or
2. you use another apn who route unsecured and secured data to different routes.
(secured data = VPN, unscured Data => www)
Check the isp apn if it use a stateful paket inspection firewall. this apn can ussually only route secured data (vpn).
Its no bug its a feature to solve some problems like too much connections, timeouts, reduction of hacker attack surface, and more..
you can find this information in the special vpn-whitepaper from your isp.
i hope this helps you.

How does the go to my p.c. app work?Is it pretty good app. Thanks

One thing I notice not all 3G provider allow VPN traffic. Orange is one that I discovered not allow VPN via 3G.

When you set up the VPN on your phone, make sure you fill out the forwarding fields as 0.0.0.0/0.0.0.0 otherwise no traffic will be forwarded through it. Testing on wifi from the same location as the host is a miserable way to test VPN as it tells you nothing. Turn off the wifi, and always test on your mobile data. There ARE carriers out there that WILL filter out VPN connections for normal user accounts and require you sign up under a business-class account to use such connectivity, this is because they want more money from you, and to not give you an easy way to get around their tethering detection. Plus in some countries, you're not allowed to possess the capability to encrypt and secure your own data/traffic and the means of encryption are banned (and therefore filtered "on-the-wire").

Use VPN Service that has open port. Like http://xtreamvpnworld.blogspot.com ive been using it for more than a year. I got no problem.

That's seems odd. Anyway I haven't tried built in vpn, how about openvpn? Have you tried it? I think built in vpn doesn't support voips like viber etc. Or maybe your vpn provider does not. I really don't know. Because I tried using droid and xtream vpn it works on every chatting platforms.

Cisco RV200W

I figured I would add some info instead of just learning. I really like XDA-dev... and go to this site often to solve issues.
I purchased a Cisco rv220w router on sale for the purpose of building a cheap network and VPN for my android (Tablets and HTC one Phones).
I am pretty good at networking so I gave it a try. In less than a day I now have a fully working network to include a VPN server that works.
VPN for all android devices uses PPTP. I know the limits and fully realize that PPTP has issues. However it is working. The VPN is designed for connectivity, not privacy. I want to avoid censorship and wifi sniffing of passwords, etc... My solution after 3 days seems to be working.
Getting other VPN solutions to work with Android seems to be a bridge to far. If there are other VPN protocols that work please let me know and I will try them. I have devices running 4.2, 4.2 and 4.4. I have a few devices running Windows. I will use cisco any connect for windows computers. Not the best but it works.
Any improvements or suggestions are welcome.

I use OpenVPN. Works very well for Android and Macs. There's a client for Android too.
You can download the free OpenVPN image from their website, but it's limited to only 2 users. For my purpose, it works great.

I will try it. Yesterday I had to reboot the router after 3 days of no problem. It kept dropping WiFi to a tablet. I will have to keep an eye on it.

[Q] wifi and firewall

hi, I just got a Galaxy note 4, I can connect to wifi everwhere but not at work. I get error that password is incorrect, I have the same password so I know my password. My stepson has a galaxy s5 and has no problem connection. I actually just returned my first phone after trying 5 days to get it connect at work. Both Comcast box and firewall have been reset. So I am not sure where to go stepson suggest change to developer operating system. I have tried safe mode, soft reset and factory reset to no luck.
This is last resort - before I return and get a different brand/model phone

if you can connect everywhere except work its your work problem. some workplaces use cisco and proprietary protocols to login to wifi after connection. if your workplace does that you will not be able to connect. no phone will. ask your work wifi to use WPA2 with AES instead of some proprietary protocol for wifi. if your son has installed some non standard rom to get his s5 to connect you will need to buy an s5 and do the same.

It is very likely that your work uses wifi protected setup. You need access to router or access point to finish setup. Ask your IT guys to help you. It needs to be done once only.

Response from my IT guys - -they are very helpful since this is a personal phone and not company issued.
I don't have a good reason for this one device to have a problem connecting to this one network. I believe we have eliminated common errors such as mistyped or incorrect password, since you have personally been able to connect other devices without issue. This also eliminates the possibility of a 1-time setup or authorization requirement, as you did not need that for the other devices. I will need to look into whether there could be a technological incompatibility between the two devices.
We will look into this further and have to get back to you.

We have a WPA2. We have people come visit all the time and have them connect.
I am just wondering in there is something in this phone operating system that is more technological updated than the systems we are using and could be the problem

I still would try to use Wifi Protected Setup. It is software depended and Note 4 is capable of using WPS while many others not. It is possible that software in Note 4 sensing that access point has that feature and requesting it. Im not network specialist but I setup few laptops for my friends. They were using Dell Vostro laptops and by default they required using WPS to connect to home network. Once that feature was disabled they connected with no problem using user password.

not possible since i have connected to both WPA2-PSK AES and WPA2-EAP AES systems. EAP requires a username/password instead of just a password.
the only system i have not been able to connect to is a WPA-CKIP and WPA2-CKIP which is a cisco proprietary protocol.

connection made

Hi all,
My Phone has connected to the company wifi. I was searching for an infinity hot spot since I am an infinity customer and was scanning and then I am connected to the company wifi. Then it began to do all these updates and I did nothing to prompt this. (weird since it can connect at home and this did not happen) I have been in contact with Samsung and have been explaining my issue - part of their process is you need to enter model and serial number- is it possible for them to track my phone - I am wondering as when I have called HP for service they can find my laptop. Very weird, but I am happy, Hopefully it will continue to work like this and I can begin to use this phone to its full potential.

yes samsung and google can both track your phone.

VPN on 7.0

Since updated to android N i was unable to connect to the VPN, trying to use as many apps but no use
They connect to the vpn network and after a millisecond it is being disconnected.
Apps:
Opera max
Opera vpn
Hotspot sheild
Tunnel bear
Cloud vpn
Pisiphone
OVPN - tells me that the tun.ko is not loaded, the funny part is that droid vpn is blocked too...
Well this country blocks all Voip apps and so
Please if anyone is reporting this issue? I think those apps still not updated to be compatible with the Nougat version

Uninstall opera max (and reinstall if need be) happened to me before on 6.0
Causes VPN to disconnect after a while.
