Re: traceroute through firewalls

Hi Carl,

By default firewall interface does not respond to ping,traceroute(icmp pkts) being security device . However, you can configure its interfaces to respond to icmp .

enable following commands:

icmp permit any outside

icmp permit any inside

Re: traceroute through firewalls

is that part of an access list or seperate commands? and why do you need to do it on the inside , does the inside not respond to ping by default, i can normally ping the inside by default

Re: traceroute through firewalls

no they are just commands . Just input those commands when you are in config mode.

check your config , maybe its already enabled for inside interface.
