Hi,

I have a Monowall 1.22 with two ethernet card(WAN and LAN). Only NAT 
configured.

The question is the next, because if I ping the LAN ip(192.168.1.1) from 
an PC connected to the LAN with packets of 1500 bytes the router don't 
response?
If the ping size is <=1472 the router response.

Please somebody can explain to me this question???


thanks very much,

Andrés
