got a very strange behaviour with a Gentoo-based PPTP-Gateway here. I configured the VPN and the default routes - from the Gateway itself, the connections out to the VPN work great. But from the Clients, connected to the Router, I just can do pings into this VPN. No HTTP-Traffic, no FTP etc.
iptables is not used and flushed, so I don't think, that's the point of failure.
Does anyone have some hints to look for?
