Subject: ICMP Ping being lost between kernel and the ping program.

Greetings. This is my first post.

I'm having a weird intermittent problem with ping.

I'm pinging the WAN port of a cheap home DSL firewall (d-link di-604) and sometimes the ping program fails to get a response,

but if I run tcpdump I can see that the response is indeed coming back.

Solved.

The Dlink firewalls were responding with stale ICMP Identifier when pinged a second time, and the ping program was ignoring the responses which had a stale Identifier.

The windows box always works because it always uses the same number for Identifier. Ugh.

Thanks!
