Hello Group,
I discovered a problem on a Sonicwall 4100 and NAT. On the external Address is the sonicwall connected, 2 hosts are behind the firewall. Host A sends a icmp echo request to an external IP, the reply comes as expected. If I now start an icmp echo request from host B to the same external IP, the expected reply comes and the reply which is usually for host A comes also to host B. On the Sonicwall itlsef I sniffed via the included packet trace and it seems all to be correct. But the second reply on host B has the sequence number of the echo request it was sent by host A, by this time host A doesn't get any icmp reply packets. Does anyone have similar problems? BTW: I have a open ticket at sonisupport since a week with no solution...
regards
