InterVLAN Routing
I am using Cisco Packet Tracer 5.2 for study, it seem to be good.

I have configure Intervaln routing on 3 coreswitches which is workign fine with vast topology. I tried to place one router 2811 as a firewall between my wan and lan. But i am not able to ping from router to core switch

Please suggest configuration for either i want to connect router directly to coreswitch i.e. wan to lan network configuration.



Software/Hardware used:
router 2811 and Cisco 3560 switch

Thanks. We'll let you know when a new response is added.

There are a few simple things you may try.
1. Run a tracert with both the IP address and DNS name to see where its being blocked at.
2. Make sure your firewall is not defaulting to block ICMP packets.
3. Open up the firewall to see if its the cause of the blockage.
4. Are there any other connection problems through the firewall?
5. Since you are trying to ping I would imagine that you are trying to verify your connectivity. So double check your wiring and intermediate connections. In a new set up thats the major cause of problems.

Good Luck!
