Well, I finally tracked down my problem to a firewall issue. But the
problem has reversed now, I can connect from the proxy server and
succesfully exchange traffic, but no PCs on the network are able to
transfer anything through the VPN conection established by the proxy.
I currently have the following iptables rules set for forwarding:

iptables -A FORWARD -p esp -j ACCEPT
iptables -A FORWARD -p udp --dport isakmp -j ACCEPT
iptables -A FORWARD -p udp --dport 10000 -j ACCEPT
iptables -A FORWARD -o tun+ -j ACCEPT

Do I need something else to make this work, maybe an SNAT rule?

Thanks,
