Hi!
I have a very strange problem with our firewall using ipfw2. Below is
my configuration file. The firewall is a briding firewall (em2,em3).
After a few seconds (7-12 seconds) of ICMP pings to a machine behind the
firewall suddenly starts blocking all traffic to that specific host.
This is also true for networks that I have permitted at the top of the
config. It rejects everything regardless of any rules I have made.
Any ideas anyone ?
# Trusted networks
add permit ip from XXXX/28 to any
add permit ip from XXXX/26 to any
add permit ip from XXXX/25 to any
add permit ip from any to any established
# DNS
add permit ip from any to any 53
# ICMP
add permit icmp from any to any
# HTTP
add permit ip from any to any 80
add permit ip from any to any 443
# SSH
add permit ip from any to any 22
# Deny everything else
add deny ip from any to any
