no access to anywhere after a couple of seconds

[Phoenix]

Hi, I'm from Iran and I have a question.
After I connect to any server using Softether vpn client manager, I only have a couple of seconds (less than 20 sec) to surf the web and after that I can not access anywhere, not even google although the VPN is still connected, so I have to disconnect and reconnect and again this short time window...
no difference between UDP or TCP.
anyone has any idea? or do you want me to send you any log or sth?
tnx

Yeah, same problem nation wide, currently no continuous connection on any port except 443, 80 and a handful of well known service ports like RDP is allowed more than 30 sec or a little more. (the delay is caused by the heavy processing required for surveillance of the entire country's connections)

basically they white listed few things and left everything else out. currently no standard tunnel based or direct IP connection will work.

things that are working:

HTTPS Based Proxies on port 443.
TOR with OBFS
VPN inside ICMP / HTTP

OpenVPN with OBFS should also work, I have not tested it yet.

Thanks Lord Farhad
I didn't know these.
Can you tell me how to setup "VPN inside ICMP / HTTP" or tell me where to read about it?
google didn't help

Softether has this feature build into it, check it's documentation, search for ICMP.
