I have a router 2821 in IOS 12.4, configured with IP dynamic NAT (overloaded) with different VRF.
IP flows correctly, but after 1 hour on the VRF_FIRST and 4 hours on the VRF_SECOND, the users application hangs.
One solution founded was to create a STATIC IP NAT TRANSLATION for one user. In this casen the problem doesn't appear. But because we have a large number of users, this solution is impossible for all user.
The only solution (for the moment) is to clear the IP NAT translation table in the VRF.
Is there a solution to resolve this problem?
Please note that we DON'T want to route between the two VRF.
Thanks for your help.
The config is in the file attached to this post:
