How do I configure protocol 50?  Is this not a TCP port?

you need udp 500 and 4500 (isakmp , isakmp with nat traversal) protocol 50
(ESP) udp port 1701 (l2tp)

tcp port 1723 and protocol 47 (gre) are used for pptp.

Subject: [m0n0wall] l2tp vpn passthrough

Hello
How can I make sure that packets for a Windows 2003 Server l2tp/ipsec vpn
are passing through m0n0wall?  The M0n0wall is situated behind another
firewall and currently has open tcp ports 50, 51 and udp ports 4500 and
1723.  Should this be enough to do it or do I need to use the IPSec VPN
settings?
Thanks for any help.
James
