Hi all,
I use a 3com 812 router connected to an hub of 6 pc lan. The lan ip of the router is 192.168.100.10, the internet ip is dynamic, so I assume for example 151.37.37.10. I have this strange situation:

ping from 192.168.100.20 (lan pc) to 192.168.100.10 (router lan ip) ->
ok ping from 192.168.100.20 (lan pc) to 216.239.51.100 (google ip) -> ok ping from 192.168.100.20 (lan pc) to 151.37.37.10 (router internet ip)
-> KO ping from 145.116.195.10 (remote pc) to 151.37.37.10 (router internet ip) -> KO
in other words, ping from any location to internet ip address of my router fail.

Which setting should I apply to succesfully ping internet ip?

TIA - Nexus.
