I'm running m0n0 1.1b17, in the PC Flavour.
I have a /28 on wan interface and i need to monitor with ICMP, a few servers 
on the LAN side. So, I made a Static NAT (server nat) to those pcs.
But on "Inbound" rules, I can only select "tcp, udp, tcp/udp" protocols.

How can I make to ping my servers from outside??

Saludos!!
