Dear all.

I would need some help because I don't know what else to try. The scenario is very simple:

I have a Vigor Draytek ADSL 2820n with a static public IP a.a.a.a connected to Internet. Internally, the network is b.b.b.b

I have a VPN connection for routing traffic from the internal network b.b.b.b to a remote network c.c.c.c. So, internal traffic generated from b.b.b.b to network c.c.c.c is routed through the VPN.

BUT, when a computer from the remote network c.c.c.c sends packets to the Vigor 2820 through the static public IP a.a.a.a, the Vigor 2820 responds to remote computer in c.c.c.c through the VPN instead of responding directly through Internet, from where the packers were received.

I would like that what is received from outside Internet is responded through Internet, even if the computer is from network c.c.c.c. In other words, I would like routing traffic through the VPN only if it generated internally in b.b.b.b

Any idea?. I would MUCH appreciate your help.

Thanks
David
