I find a problem thatunable to ping internet(for example 8.8.8.8) form
FWSM(I have been ssh to FWSM) recently.But any business is worked fine
through FWSMtraffic.
and I can ping direct interface with FWSM outside interface.
If FWSM have local security conceptand the local security zone unable
ping outside?or other cause.
