RE: Static NAT entries timeout value?? [7:37910]
Exactly...I didn't think that a clear ip route trans * would do as you correctly say that it is for dynamic trans. Thank you for your help.

For deleting sub interfaces, you need to reload, but for nat translations use: clear ip nat trans * -Joe - Original Message - From: "s vermill" To: Sent: Monday, March 11, 2002 7:41 PM Subject: RE: Static NAT entries timeout value??

RE: Static NAT entries timeout value?? [7:37910]
'clear ip nat trans *' might have an effect but it is *supposed* to be just for dynamic translations. As for clearing the route cache, I think this is a process so I guess it wouldn't be cached anywhere. Thinking outloud.

I wonder what would happen if you cleared your route cache?

RE: Static NAT entries timeout value?? [7:37910]
If you can reload the router I would do that. Very strange but not uncommon. Someone here recently had a problem where a router was load balancing accross deleted subinterfaces.

Static NAT entries timeout value?? [7:37910]
Hello, Is there a timelimit on how long a router keeps the static nat entries in its buffer EVEN though you take out the entries from the router? I can still ping the ip's from other routers even though I took out the entries on the nat router. I would think that this would only be possible if the router keeps the entries in its buffer but am not sure?? Thank you. Regards.
