Unexpected VPN traffic blocking
Posted: Mon Aug 18, 2014 4:38 pm
Hi all
I am from Russia, I have SoftEther server on my home server. Everything working great, I can connect to this server and work from many different ISP, like cell phone Internet, Internet access on my work , etc.
Except one place! This is my another apartments, where I live. ISP in that place - local town provider, I connected truth pppoe connection and wifi. SoftEther listen 443 port udp, authorization with certificates.
What most interesting here, that vpn connection works good, no disconnection or something like this, but I cant load any http/https/icq/skype/teamviewer/etc services, no any incoming traffic. At the same time icmp-packets going to any resources, I can ping or tracert everything in the world. Routing table looks good and again, from any others places everything with same settings works great.
I checked l2tp authorization on my mac and received absolutely same situation.
Also I have a Debian Open VPN server working on VPS with tls-auth in another country. So… absolutely same situation.
I suspect that it can be something like DPI inspection, but SoftEther as I read, from outside looks like usual https connection.
Probably we can look deep in this case, maybe it’s something like GFW in China. I can share any SoftEther logs or WireShark logs, or give remote access to the server for developers.
Thanks
