Hello All,

I am currently having a ping issue with my FWSM and was wondering if anyone could provide some insight. So, I have a 6500 along with an FWSM running in transparent mode. This is a test environment so I can make changes at any time. Below is the show run for the FWSM. I can ping the SVI interface along with the HSRP interface from the FWSM, and vice versa. However I cannot ping any outside addresses from the FWSM and the FWSM produces no long output when I try to do so. I can also not ping from the 6500 or the FWSM to the test host. The test host has full internet connectivity and can ping both the 6500 and the FWSM however from the 6500 or the FWSM I cannot ping the host. I get the following error in the ASDM when I try tio ping from the 6500 to the Host. is the SVI and is the host. Thanks in advance for all the advice.

I've noticed that I am able to ping the Natted IP of this host from the 6500. So, it seems as if the FWSM is seeing pings from the 6500 as Outside traffic so I will change the soruce these packets come from and give a reply back. However I still cannot ping outside from the FWSM.
