Hi I am back
Let me explain my design again, with some extra explanations.
An L2 switch with the network 10.250.249.0/24
is connected to the 3550 switch.The Websense server for the PIX is connected to this L2 switch .All ports in the L2 switch is in VLAN 1.
The other 2 connections on the 3550 switch has to be as routing ports.
One comes from an ATM router (which has an ATM interface with many point to point ATM subinterfaces from the company branches).The router interface is 192.168.249.1/24 and the 3550 switch interface is 192.168.249.254/24. EIGRP 200 has to run between the 3550 switch and the router.
10.250.x.0/24 (please do not confuse it with the 10.250.249.0 network on the L2 switch connected to the 3550 switch ) is the network at the company branches at different location which is connected to the ATM router at the main branch as subinterfaces through the ATM subinterface IP addresses 10.29.x.x/30 .My aim is to connect the 10.250.x.0/24 network in the branch locations to the internet through the ATM router, 3550 switch and the PIX firewall in the main office.
Static routes have been set on the ATM router towards the store routers and route-map has been set on the routers at the branch sites for the routes in the opposite direction to the ATM routers corresponding ATM subinterface .
The other routing port on the 3550 switch is to be connected to the PIX.The PIX inside interface is 192.168.248.1/24 and the 3550 switch interface is 192.168.248.254/24.
The PIX is connected to the internet through the default gateway 18.104.22.168/24.
The outside interface of the PIX is 22.214.171.124/24.
What else should be done to complete this configuration.
What should be configured between the 3550 switch and the PIX. If I need a default route on the switch where should I point it to?. Or should I configure static routes on the 3550 switch.
Is there anything left on the ATM router to do other than setting static route towards the branch location router and an EIGRP between the ATM router and the 3550 switch.
