http://serverfault.com – I am currently in the process of modifying how internet reaches my front end servers and I am having a strange issue with one of the existing stacks. There is one physical firewall which is above the server, if I use this, I start recieving packet loss across the entire subnet, if I use wireshark I can see arp requests but I still get packet loss. The second I take this firewall out, the problem dissapear. If I route around the firewall straight to the front end server, I still do not get any issue. All of this leads me to believe there must be something wrong with my config but I cannot see (HowTos)
