It may not be a firewall rules problem. ipchains may not be enabled. It is also possible that the echo responder is not enabled. At 9:03 PM 6/3/04, Joerg Bruenner wrote:

Looks like you don't have any rules, but it also doesn't make any sense that if ipchains is working you then wouldn't have any packets.

Ping from the firewall-box to box A will be answered. A ping from box A to the firewall reaches but will not be answered.

What do I have to do ?

Make sure you've got the ping service enabled on the box you're trying to ping! -- Fred Morris fredm3047@inwa.net (I-ACK)
