I have an FWSM context that we use to secure our Network Management vlan. Vlan 900 is level 100 and vlan 200 is level 0. We use static NAT translations for all devices behind the FWSM. The outside of the FWSM via VLAN 200 connectes to the the rest of our Internetwork. I am able to access everything on our network just fine including all of our Intranet web servers.
Our main firewall is a PIX 515E. THis PIX is the main egress point to the Internet.
My problem is that when I try to get to certain web sites from devices behind the FWSM I have problems getting all of the content and other times I don't get there at all. If I wait a little while I can try again and will usually get the site up. It seems to be worse on highly dynamic websites almost like things are timing out.
Does anyone have any experience running through two firewalls and possible issues?
