We placed a FWSM in our 6513 to replace our external PIX525. I'm able to session into the FWSM. We are not ready to switch over as yet. I just want to work with the FWSM a bit and get things ready. I created a VLAN15 on the 6513 and presented it to the FWSM. I created an interface and assigned an IP subnet on the 6513. I sessioned into the FWSM and assigned the presented VLAN an IP address. I named it inside and gave it a security level of 100. I setup a laptop on the VLAN and gave it an IP address on that subnet and added an icmp statement to allow the lpatop to ping the inside interface on the FWSM. Works. I added a telnet statement to the FWSM for the laptop. I can't telnet to the FWSM. I also tried enabling http for the laptop and that doesn't work as well. Not sure what I'm missing. I have not added any SVI outside interface to the FMSM as yet since we are not ready to switch over from the PIX. FWSM shows version 2.3(4). We are using only static NAT.
We have multiple VLANs on the 6513 that will all use the same outside interface on the FWSM. The VLANs route to each other inside the 6513. Some VLANs have more then one subnet defined as secondary on there interface.
