[nsp] IP NAT question

[Eric Helm]

I have an odd situation that requires an inside host (192.168.110.2) on 
the Ethernet0 port be NATed to a public address on Ethernet1 port for 
internet access, but no NAT for other specific networks that reside on 
the E1 side of the router. Any good suggestions on how to accomplish this?

NAT to the internet is easy enough, but how do I prevent the host from 
being NATed if the source or destination is one of the networks I 
specify on the E1 side?

Thanks,
/Eric
