cisco 2801 nat problems

[kalderini]

I have cisco 2801 with  ios ipbase-mz.124-1c.bin   .

All my lan used the cisco 2801 for nat and go to internet.

but when

over time and the number of translations increases all lan internet runs out. to solve the problem we must reboot the router.

We believe the problem is that the 2801 can not handle many translations, might improve the performance by changing the IOS for advance service? or some other solution using the same HW

hi,

try configuring a NAT timeout, perform a "clear ip nat translation *" and monitor again.

ip nat translation tcp-timeout

ip nat translation udp-timeout
