i have upgraded my network and i have 3 routers 7609,3660,3745 and 2 4500 switches in HSRP mode all in EIGRP routing for my 500 wan locations and then i have my netscreen firewall 208 which allows the traffic to the server farm and the internet .The problem i am facing is that there is session time out at the server when the users are running a broad query say a sql query which is quite lengthy the wan locations are through static routing to the main router that is 7609 which is agian in EIGRP routing along with the 2 other routers i mentioned earlier.
moreover i am not getting the desired through put from my network upgradation which is becoming a nightmare for me.I have serious doubt on the compatibility issue between the cisco 4500 switches and the etscreen firewall pls help me out with the solution.moreover after network upgaradtion there is lot of delay at the local area network .on the 4500 switches i have made 4 VLANS of user series the othr for router and then for server farm.
