Hello,
I need help on this.
I've got a PIX 525 for testing. One of the interface leads to the
Internet, all the others are from the private ip space.
From a host located behing "internal1", I try to ping the ip of
www.openbsd.org and it does not get through. The access list applied
on the interfaces is permit icmp any any.
Can anybody tell me why show xlate does not show private ip being
nated to the external IP of the firewall?
How do I make sure all the private networks I have will be hide-nated
using the ip address of the external interface?
Thank you very much,
/alain
