NAT rule missing from a running-config

volkovvalery · ‎05-16-2008

Hello.

We have Cisco 2851 (c2800nm-adventerprisek9_ivs-mz.124-15.T4).

Periodically the nat rule:

ip nat inside source static ip1 ip2

missing from config.

Why this happens?

Can anybody help me?

does it happen after a reboot ?

No, uptime on my router more than 1 week.

If i replace my rule on

ip nat inside source static tcp ip1 80 ip2 80

It also missing after some hour's of working (frequently this happens in night hour's).
