You need to setup your firewall to Proxy ARP for the internally NAT'ted
addresses.  We do this quite extensively actually.  

On the Nokia boxes you go into Voyager and add a proxy arp entry under the
interfaces choice.
In FW-1 add two objects.  One os the actual internal object with a NAT
defined on it for the external rule.  Then add an object that is the
external address as a "placeholder" for the actual rule.

On Sun - I'd have to go look it up.... haven't done inbound NAT there
(somebody wanna enlighten us?)

On NT - shame on you - get a real box....

Example:

an internal mail server with address 192.168.1.5   it's valid external
address is 200.100.10.10.  named mail1 or something

then a placeholder object with just the address 200.100.10.10  i usally name
these the same as the first but with a -valid tag (such as mail1-valid).

In a rule say 

Any     mail1-valid      ftp, http, smtp (whatever)        target to install
and logging as you choose


Kapische?  Hope that's clear....

Subject: [FW1] How to setup ftp and htttp w/ FW-1 External Interface
Only



Does anybody knows how to redirect ftp and www  to internal servers with
only fw-1 external (valid ip) address. I also have interal users that
need access to http,ftp, and telnet. I have done NAT with internal users
going out via a NAT hiding translating rule and ftp and www are done
with static rules. I also have appropriate access rules in fw-1. I can
see packets entering the fw in the logs but it seems like they are not
routed (or getting out of the fw).

Thanks in advance
