FWSM w/ Multiple CXT understanding..

I am trying to get my config working with 6500 and Virtual FWs with an FWSM.

My first issue is that I cannot even ping from my VLAN5 outside interface which was created in the MSFC and has been allocated to the FWSM admin cxt 'outside' interface. I'm not sure if I need to setup static(inside,outside) mappings on the admin context? Vlans 10 & 20 have also been allocated to the FWSM module but I'm stuck. Can someone please advise on how I can get ip connectivity through VLAN 5 (admin cxt) down to vlan 10 inside (customer-a) cxt?

Re: FWSM w/ Multiple CXT understanding..


Please add 'icmp permit any outside' in FWSM configuration.
