Host using static nat, but attempting to send all internet traffic out overload NAT

lcnorwood · ‎07-22-2010

I have a static nat for a video conferencing host (polycom) When I attempt to send out traffic, it appears as if it's coming from the overload nat address rather than the static nat it has.

IE

Static NAT 45.3.18.211

Overload NAT: 45.3.18.194 I have a /26 range on the outside.

What might cause this? Any rules I should check for?

It may help if you include the relevant nat configs...

( "show run | i ip nat" and any acl's or route-maps you have referenced in those statements).

You could potentially use an acl on the overload to deny the polycom source address, and permit everything else.

I would give this a try if you are sure that your traffic from that host is being overloaded.
