Hi!

OK. I have this situation


VPN_CLIENT(w2k box) ---> router ---> FIREWALL (NAT) ---> M$ Server


I want to configure only the Firewall.

First, I tried to create a connection with pptp. Pptp need protocol GRE and
iptables don't support nat with protocol GRE. I must recompile the Kernel...

M$ server also supports ipsec and l2tp. Is ipsec/l2tp supported with
iptables without recompile the kernel? It's more difficult???

Thanks!
