Packet Filtering for block ICMP Traffic

Hello Ray,

I've got the same issue. It seems that the packet filter drops some ICMP reply coming back from the destination.

I've managed to make things work correctly by modifying the packet filter rule and adding the following condition :

and (icmp[0] = 8)

This will tell the filter to only drop icmp request from outside IP, the icmp reply will never be dropped.

Hope this will help
