Pinging VPN pool users

[gavin77]

Hi,

I need to set my pix up so I can ping users connected to our VPN pool and also get a echo reply from them,

VPN pool - ip local pool vpnpool1 172.31.254.1-172.31.254.8

would access-list permit icmp any vpnpool1 echo reply work?

CHeers,

Gav

Try this:

access-list inside_access_in permit icmp any 172.31.254.0 255.255.255.240

Whats is the source IP you are ping from?

source ip will be on either 10.99.25 / 26 ranges, only a few servers / workstations on our LAN that have direct acces to the PIX anyway, which of the above commands recommended will work best??

cheers

 

[NetworkGhost]

This should work.

access-list inside_access_in permit icmp any 172.31.254.0 255.255.255.240

the fixup will help with ICMP error messages. You will need an ACL to allow the request outbound.
