Traffic behavior on 3750

Unanswered Question
Jan 11th, 2011

Please see the attached for diagram.

My issue is that when we perform an IPerf test between two servers, somehow the traffic traverses via the firewall LAN interface ( I see the traffic on the firewall LAN interface spiking during the test)

Why isn't it that the two servers are talking to each other directly local on the switch versus going via the firewall gateway.

Am I missing anything?

I have this problem too.

Yes, - It is based on S.MAC and D.MAC of two servers (layer 2)  such that if server 1 want to communicate with server 2, it send  ARP request for the MAC address of server 2  then the server 2 will receive the ARP request and respond to it, and then both servers will communicate directly without going to Gateway.

Not sure if the firewall has proxy arp enabled for that LAN??
