I have a Pix 501 running software ver 6.3 that is used to allow vpn connections to a network. One day it stopped letting anyone connect, the vpn client says the remote peer is no longer responding.
I would like to test port 0 on the pix to see if it has gone bad but not sure how. Should it respond to a ping request?
This is my first experience with a Pix device so any advice is appreciated.
