NAT on MSFC

Hi,

Has anyone gotten something like the "nat 0" command on a PIX to work on an MSFC? I'm trying to get specific traffic to pass from an inside interface to an outside interface without being natted.

Thanks in Advance,

Drew

Re: NAT on MSFC

the nat config on a pix is altogether different than nat in IOS.

First question, did you order the firewall feature set for the mfsc, I think

you need that first.

If you don't wish for your addresses to be NATed on IOS, just deny them from the access-list you use to define NAT.

ip nat inside source list 1 interface serial0 overload

access-list 1 deny 203.24.1.0 0.0.0.255

access-list 1 permit any

In this case, the network 203.24.1.0 will *not* be NATed, but will be routed. All other addresses will be NATed (PATed) to the IP address on serial 0.
