Re: pptpd problems

That's usually because of iptables rules not allowing forwarding, or routing rules not set to route the right kind of ip range to networks used.  In iptables usage, the issue may be that ip forwarding isn't setup between ppp interfaces and the internal network.  We'd need a bit more information on your network setup, the WRT54GL may need to also have additional tweaking done.  the pptpd server may not have the right iptables rules to allow traffic to forward between ppp* and eth* that are on these respective networks etc.
