FWSM - multiple context, transparent firewall issue

Hello,

I have configured admin context on my FWSM as transparent FW with vlan 911 being the outside and vlan 11 being the inside interface...

I have created both inside and outside ACLs to be permit icmp any any and ip any any but somehow hosts on the inside are not able to pass through anything that is on the outside... and I do not know where is the mistake that I am making? I have seen two other posts with the same problem , however, no one has actually replied with an answer.. I am attaching the config on my FWSM (ver 3.1.8).

Thanx in advance for help..

Are Vlans 11 & 911 created on MSFC?

Are these assigned to FWSM?

Are vlans 11 & 911 created on FWSM?

Re: FWSM - multiple context, transparent firewall issue

yes they are. when you issue show vlan on the swich you se the vlans 11 & 911

they are assigned to FWSM through firewall vlan-group 1, 11,911

and yes, they are created on FWSM and named as inside and outside..
