I have a problem with a fwsm on a 6509. I am on vlan1 and I want to ping a pc on vlan2. I find this error :
Deny inbound (No xlate) icmp src Vlan2:x.x.x.x dst Vlan2:y.y.y.y (type 8, code 0)
If I ping another pc on the vlan2 I don't have any problem. I know this error occurs because fwsm doesn't permit traffic when src and dst are on the same vlan. My question is: why does firewall see my pc on vlan2 even if my pc is on vlan1?
There is a NAT exemption rule from vlan1 to vlan2.
