I have a microsoft server to l2tp/ipsec. And my firewall is a Linux. I understand that if i create a server in micro$oft box, i can routing the traffic with Linux with any problem (no recompile, multiple users, nat with l2tp/ipsec). Is it true?

IPsec does not use GRE. IPsec uses protocols 50 and 51 - ESP and AH. IPsec works fine over NAT in Tunnel Mode (not Transport Mode without serious fiddling with things). GRE is protocol 47. L2TP is a UDP-based protocol (port 1701) as far as I know. Regards, Antony. -- Your work is both good and original.
