[c-nsp] basic nat question

[Church, Charles]

What's the purpose of having those additional addresses bound as
secondaries?  It's not needed for NAT.

I really did *not* want my first post to cisco-nsp to be this lame,
but...

if you have second-

got an 1841 out there, with x.x.x.161/29 bound on the internet facing
port, and .163, .164, .165 also bound as secondaries.  

need to do some static nat, but only the entries for the primary IP work

eg

ip nat inside source static tcp 192.168.1.103 110 x.x.x.161 110 vrf ISP2
extendable

works just fine

ip nat inside source static tcp 192.168.1.156 443 x.x.x.163 110 vrf ISP2
extendable

does not work

a clue that I'm unable to make use of is the traffic that I send to the
secondary, comes back from the primary according to the nat trans table,
and as verified by packet capture

any help you could provide would be hugely appreciated

running 12.4.24T..

Thanks-
Ryan
