I have ACE 4710 which is connected at the center of the network and ACE connected to the LAN and outside connected to the Firewall where my DMZ is connected.
Whatever traffic is passing from inside to DMZ it is getting slow. When I pass the ACE things are started working fine.
My ACE is only redirecting the port 80 traffic towards the proxy server. I have bypass the Application Server located in DMZ (172.16.0.0 subbet) and inside Subnet 192.168.200.0 192.168.205.0 from redirection.
But when application server connected in DMZ (172.16.11.126) talks with SQL server 192.168.200.0 and 192.168.205.0 subnet it get stuck and taking too much time to fetch the data. But when directly connected it is working fine.
I have no access-list in ACE, only load balancing and redirection of port 80 is configured in the ACE.
I have checked the FTP setup, directly connected with Firewall FTP is excellent but when i introduce the ACE it is taking same slowness and very very low throughput.
Attached is configuration of the ACE. I have checked teh switching part of the network it is fine and firewall part also because only when ACE is coming in network I am facing slowness.
ACE has default route towards Firewall and static route towards teh core switch connected to the internal network.
Please let me know where i am missing and how to avoid this slowness. I m complete network from internal sever to dmz server are gigabit ethernet.
