Re: [FW-1] Redirect trafic on FW1-4.1?



Depending on your platform it is pretty straight forward. ProxyARP the
external address then add a route between the 2 addresses with a rule
allowing specific traffic.
As for the second part, Why? Surely it would be aVPN to the internal
Address.

Subject: [FW-1] Redirect trafic on FW1-4.1?


Hi.
Im wondering if it's possible to have an internal host, let's call it
192.168.1.50, running some service, say a webserver or ftp server, and
have FW-1 redirect requests sent to a public address? Say you have one
box, 192.168.1.50, and you need to let people in to it from the outside,
but getting another box to do proxying, or putting this host on a public
address is out of the question. Is there a way to work this out with
FW-1 4.1?

I've done this with OpenBSD/PF, where the rule would look something
like: rdr on if1 proto tcp from any to 150.160.170.180 port x ->
192.168.1.50

Anything similar one can do with FW-1?

Oh and to expand on that a bit, a more hypothetical question, could one
create a VPN connection to this "fake" host(150.160....) and have that
reach the internal host as well? Something like this(sorry my graphical
abilities are...lacking, I know ( VPN_West - VPN-GW-W - Internet -
VPN-GW-E - VPN-East(fake host) ) rdr-> 192.168.1.50

If anyone can help me out here you'll make my day, a few days in fact :9

Regards
Johan
