RE: [FW1] Outbound NAT problem



sounds like your missing the NAT rule for AS01.

Subject: [FW1] Outbound NAT problem



I am having an issue with outbound NAT and a particular host on my network.

I have a host on the internal network named AS01. It has a static NAT setup
for external IP address.
I have another host named AS02. It has a static NAT setup with an external
address similar to AS01.
I have a rule on the firewall that NAT's all hosts on our network to the
address of the Firewall.

My problem is as follows.

When packets leave AS01 to the Internet they should go out using AS02's
external address. What is happening is those packets are going out using
the firewall's external address as if it was a host on our LAN. Technically
it is a host, but it also has this static NAT.
If I try the same thing with AS02 it works fine. It goes out using AS02's
external address.

I know the NAT is working correctly because I can telnet from the outside
in, using the external address of AS01 as the destination.

Anyone have any suggestions?

Thanks,

-Brian
