I have implemented a network where 2 sites are connected through 1 router 3660 on each by 2 mbps leased line. Pix 515 firewall is placed at LAN on both ends. Intervlan routing is done by PIX. Pix inside, outside & router Ethernet interfaces is getting connected to Cisco 2950 Layer 2 switch. The same configuration is happen on end point. 2 vlans(user & server) has made on pix & advertised over 2950 switches. Server security zone is 75 & user’s is 50. Every end requires access to server vlan of another end & user vlan is only user for accessing local resources. Currently for accessing any server, I open IP to IP permission on PIX at both ends. Now all required servers & applications are accessing through both point apart from ‘Hummingbird Exceed’ Application That’s run on SUN server. We can ping Sun server IP address & access it. If I remove PIX at any end & place intervlan routing through router, then I get access to exceed application. Pls. give me resolution whether it’s a network or application problem.
