Multiple Nat in PIX

hbartz · ‎11-17-2001

How are different networks inside a PIX 515 natted? We have a frame-relay cloud consisting of 3 remote Networks(192.168.1.0, 192.168.2.0, 192.168.3.0)with currently no DMZs. On the same Network as the 1720 frame-relay router and PIX is a IBM Whistlejet router that does DHCP, mail relaying and other functions. This was our previous gateway to the Internet. It also contains the routes to the x.x.2.x and x.x.3.x networks. The first network is natted with a public IP address. Can the other networks be set up the same way with remaining global IP addresses I have left in my pool? How would that be configured in the PIX?

Thanks

All of your networks can be natted with a single NAT command:

Global (outside) 1 x.x.x.x-x.x.x.x netmask x.x.x.x

nat (inside) 1 0.0.0.0 0.0.0.0

This will allow all your internal networks to be translated. You do need some static routes for your remote networks.
