ipchains: unknown ICMP requests ...
Hi there,

we're using ipchains as firewall. Everything seems to be fine, but now and
then, we're getting ICMP requests (PROTO=1) from low ports (1-8) to our
webservers at ports 0 or 1. I can't figure out, what's the matter with this
requests, it doesn't seem to hurt anyone, that the requests are blocked by
our firewall. Is there any intelligent DENY-rule for this sort of requests ?

bye,
P.
