Configuring NAT on FWSM in Transparent Mode

I'm having some trouble configuring NAT on FWSM on transparent mode. I think I have the NAT configuration right. but the firewall does not want to accept the packet from the upstream router.

I'm trying to nat 172.20.99.240 to 66.37.67.121

I have a route in my upstream router 66.37.67.121 to 172.20.99.4 (fwsm ip add)

Tracing route to natpool-0.citizenstv.coop [66.37.67.121]

over a maximum of 30 hops:

1 <1 ms <1 ms <1 ms ctclan1.citizens.local [10.10.10.1]

2 1 ms 1 ms 1 ms floyd-core2.swva.net [66.37.65.3]

3 <1 ms <1 ms <1 ms 66.37.64.130

4 1 ms 1 ms 1 ms 66.37.64.129

5 1 ms <1 ms <1 ms 66.37.64.130

6 1 ms 1 ms 1 ms 66.37.64.129

7 1 ms 1 ms 1 ms 66.37.64.130

Thank You

Re: Configuring NAT on FWSM in Transparent Mode

Could you post your configs?

I am interested is seeing that the transparent firewall let you enter them (I have not tried it). NAT is an unsupported feature in a transparent firewall.
