Hi all,

I'm an absolute beginner on the netfilter stuff, so please bear with me here.

We have a device running linux 2.6.19 kernel with iptables installed. It acts
a a gateway for a another mobile device that connects to linux device via irda
port - ppp connection. I've managed to port forward telnet port to mobile device
with the help of this page http://kreiger.linuxgods.com/kiki/?Port+forwarding+with+netfilter.
Our customers want to be able to ping the mobile device behind the linux firewall
and IMHO it is not possible for ICMP packets to be forwarded since it is a protocol
by itself (not a TCP/UDP style service).


Is it possible to 'port forward' ICMP requests?

Thank you,
HK
