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

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

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.

[Q] Upgraded MS2 Froyo to Gingerbread, now Mobile Hotspot doesn't work any more?

Has anyone got Mobile Hotspot to work on their MS2 after the upgrade to Gingerbread?
I've been having problems - Tte MS2 properly assigns an IP address to PCs that try to connect to it over WiFi, but the connection doesn't seem to go past my MS2 to the Internet. Same thing whether USB or WiFi.
I'm on T-mobile on the USA - could that have something to do with it, some kind of authentication is being performed now (that wasn't being performed on Froyo?)
I had this problem too.
Now I use the app "barnacle wifi tether" and it works fine.
I'm from Brazil...

Thanks for the suggestion. If I root my phone I'll consider that option. Has anyone found any other fixes? I tried playing with the APN settings as suggested by some online, but it doesn't seem to help.

Usb sharing is f*d up - dnsmasq does not launches properly and phone gives no IP in response to dhcp req from pc. I don't remember, if setting an IP and gw manually solves the problem.
However launching _both_ sharing method at once helped. DHCP worked fine. Maybe launching wifi hotspot alone generates similar problem?
Did a factory reset and now Mobile Hotspot works!
Haven't tried USB tethering yet, will report back when I do.
Great! I also had this problem and this tip helped me.
Mobile Hotspot works but haven't got USB tethering to work properly yet. The computer can get an IP address from the phone, but no connection through to the Internet. This is after the factory reset.
Same with me here.. Already did FR but still no go..
Old thread I know but anyone sorted this yet, as its doing my head in, I even changed to a tethering plan in case i was being blocked.
Barnacle Tether doesn't work either same symptoms also says DHCP:Could not bind to DHCP port Address already in use

Could it be your carrier blocking 3G tethering?
Hi
3G tethering is not blocked by carrier as I am on a tethering plan and have spent a long time on the phone to an Indian call centre to sort it.
But joy of joys after trying everything I could think of including re-flashing and wiping all data etc. I have managed to get it working using wifi tether for root user

Global authenticated http proxy

I'm a University student who would love to use this tablet at uni. Connecting to "eduroam" is not a problem but the proxy support in samsungs rom is. It's easy to put the proxy details in the wireless advanced settings and get the default browser working. But without dropbox and a few other key apps, it's useless.
I previously had an Iconia a500, rooted with various roms over the time I had it. I found an app called proxydroid which worked brilliantly with all of the roms and even started the global proxy specifically when connected to eduroam the uni network. My problem is this app no longer works, i've tried every other proxy app out there and can't seem to get it working. Interestingly enough my original Galaxy S worked fine as well but my new Galaxy Nexus running cm9 has the same problem.
I can't figure out the underlying cause! Any help would be appreciated.
I use proxydroid with no problems at all

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] VPN issues

Hi
I am using a g900t with the AICP ROM 7.0 release and I am having some issues with VPN. I purchased VPN access from StrongVPN (If you know of a better provider please tell me who and why). I added my VPN credentials to the built VPN section of the ROM and it connects but randomly quits after awhile. I tried setting up the Always On VPN option but when it connects i have no internet access?
I am new to VPNs just trying to get something fast and reliable set up but feel i am stumbling around like a fool. Any help?

[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.
