FSWM Routed Context Issue

Muhammad Zubair — Mon, 11 Mar 2019 14:02:09 GMT

I have configured routed context in FWSM but it's not communication event with outside and inside directly connect router (MSFC). When I try to ping outside router IP address it show error in debug.

Denied ICMP type=0, code=0 from 192.168.15.5 on interface outside

I have configured IP any any and ICMP any any on both interfaces.

Hi,

Can you configure "icmp permit any outside" and then try pinging again and see if you get a response.

Regards,

Arul

Are you pinging from the FWSM or from a host connected to inside interface?

If you are pinging from the FWSM and not "through" the fwsm the ping is permitted or denied based on the icmp command.

Use

icmp permit 0 0 outside

If it were a ping through the FWSM it would

be controlled via an ACL.

I am Ping it from FWSM and ACL configured for ICMP on both intface (inside, outside).

As I said earlier in order to ensure that the Ping reply reaches FWSM you need to use "icmp permit any outside" command.

ACLs are only used for traffic through the FWSM .
