NAT problem

jopetik09 · ‎12-22-2010

Hi All,

I have a router 2951 and IOS 15.0(1)M1.
The below is the nat statements are configured in that and all are working fine except the one in red color is working for some time say 5 days and stopped working (not stable).
can someone tell me what is that cause and how it can be stable

ip nat Stateful id 1
ip nat pool nonat 206.180.114.x 206.180.114.x netmask 255.255.255.0

Thanks in advance.

It strikes me that the line you have problems with is the only one without the keyword "extended".

Perhaps your application needs extended translation?

Please adjust and check if it resloves the problem.

Hi Leo,

No luck with extended word added to that statement.
Actually statement was there with extended word and one guy from the same forum told to remove and check.
But it is not working stable in eigher ways (remove extended or keep extended)
