Hi all,
I seem to be having problems with a NAT config. Currently NAT is
configured on a 6506 which is running native IOS. I have 4,000 users
natted to 13 IPs and my processor utilization is not too happy about
this, its sitting at 80& util now.
I have tried tweaking timers and such on NAT but no dice. Is there any
thing else that i can do to aleviate the cpu utilization?
Here are my timers
ip nat translation timeout 180
ip nat translation tcp-timeout 300
ip nat translation udp-timeout 30
ip nat translation finrst-timeout 15
ip nat translation dns-timeout 15
------------
Here is my NAT config - some of it
ip nat pool Towson_U xx.xx.xx.11 xx.xx.xx.23 prefix-length 26
ip nat inside source list 99 pool nat_router overload
access-list 99 permit a.b.0.0 0.0.255.255
where a and b are private IPs :)
the xx.xx are publics :)
So i have 13 VLANs going to the pool nat_router.
Any thoughts?
Thanks
Imo
