Firewall broadcasting

guys,

i have configured a new 525 Firwall into my network recently, but something starnge happend to the internal network.

i noticed slowing down the entire network some times some of my application not responding and getting dissconneting (even the pinging inside the same network oscillate ).

does the firewall generate such aproblem (broadcasting) ??

i've attached the config

thanks in advance,

hasan

Re: Firewall broadcasting

Firstly you are running an obsolete code on the new FW (6.2.2)

Secondly does sh int shows up any error on interface ?....also what are the instantatenous values for sh conn count..sh xlate count (when the issue occurs)?
