Get to NAT'd address from inside

Aug 29, 2005 1 Replies

Hi folks,



forget security and all other stuff, I'm simplifying the network here to keep it simple to understand...



I have a PIX501, on the inside is 192.168.0.0, on the outside is



193.194.193.192 (public IP). I have 1 client on the inside 192.168.0.1 which is nat'd also with the address 193.194.193.193. I want to be able from the inside to connect to 193.194.193.193, can I do it? Or do I always have to use 192.168.0.1. You see the issue here is that I have software which is licensed to 193.194.193.193 and it won't let me use it if I connect to 192.168.0.1 so I always have to use an alternative route to the internet, like my broadband or something and this is quite a pain.

cheers Dave

Not without adding additional equipment. PIX 6.x never allows loopbacks on the same interface, and the PIX501 is only able to use the two interfaces with no possibility of using the work-arounds available on the other models.

Sorry, you'll have to add at least one more device into the mix. That device could be something like a Linksys BEFR11S4 or other simple NAT'ing ethernet-to-ethernet router.
