Hints

Before the router went down today

erase nvram

followed by

reload

and

copying of a new configuration was done last week.Three differnt times.

Also ,one of the nat lines was edited today.Could this have caused the problem ?

I await your reply urgently.

Thanks

Re: Router down !Could not expand chunk pool for ipnat node. No

Something seems to make your router run out of memory.

Check if your router meets at least the minimum requirements for the IOS and if it is a real busy router I'd say double it.

With the type and version of IOS you can find on CCO what the requirments are.

You can also see if cisco has not withdrawn the image due to bugs.

show version on the router tells you what you have for IOS version, ram and flash.

Cheers,

Michel
