1720 stops translating outbound NAT

We have just started having a problem with a 1720 stopping outbound
traffic due to not translating NAT any more.

Is this a known issue with this router? Thanks.

Jon

 

Nope. Out of memory maybe? Sometimes a spam infected machine behind the
translator which is spewing connections to all over everwhere chews up all
available RAM in a router.

 

Well, this problem has been occuring with less than 20 or so
translations active, so I would hope that this wouldn't be an out of
memory thing. But, we stopped some people from using P2P software
that shouldn't have been on their machines in the first place to cut
down on un-necessary connections.

Has anyone else seen this problem before?

Thanks again,

Jon

 

This appears to be happening with very few or very many connections.
I wouldn't think that a memory problem would be causing it, though.

Would there be something to look at in regard to what is consuming
memory?

Thanks again.

 

What's your IOS version? We ran into some IOS bugs that stopped NAT
translations (on 7200 VXR series)

We have 12.2(7c) running atm.

You may want to do a bug scrub. Our version was 12.1(19)E3. I can't
remember what Cisco gave us for the fix, but 12.2.7 may not have it.
