Can other hosts ping this machine .25?


Can FWSM ping other hosts in the 172.17.10.x subnet?


Its most probably a routing issue.

hi frd..

172.17.10.25 is a source ip address..I am getting same response from 172.17.117.24 to 172.17.10.25.Those systems which are behind FWSM contex are experiencing this issue..

Hi ,Contex configuration is simple as inside & outside ,there is no shared interface.. for outside interface I have comman VLAN ,which is catering to five contex

How are you classifying packets then (mac-auto,static NAT etc)? because you are using a shared interface. From which zone are you initiating the ping?
