vpnclient doesnt work with server behind DS-Lite

Post by Ernst Ahlers » Fri May 13, 2016 11:33 am

Hello,

we've setup a Softether server (4.20 Build 9608) on Windows 10 (Pro, x64) behind a router with a DS-Lite connection (Vodafone Cable Internet, native IPv6, but AFTR/CG-NAT for IPv4, so no public IPv4 address on the router).

The Windows client (4.20 Build 9608) running under Windows 10 (Home, x64) does connect from an IPv4 only LAN (NAT router on Vodafone DSL).

But vpnclient (4.20 Build 9608) on the same machine under Ubuntu 16.04 (i686) with the same config does not connect. It keeps on retrying endlessly. I did export the VPN settings from Windows to Ubuntu so there shouldn't be any config mistakes.

Has anyone else already seen this effect and maybe solved?

Best regards

Ernst Ahlers

I think there is something like firewall in the Ubuntu machine.

Thanks for the hint, thisjun.

The firewall wasn't enabled.

Meanwhile we've been able to solve the problem. We recreated the config locally on Ubuntu. Then the machine did connect.

Best regards

Ernst
