ACL question

Our internet router is open to all traffic until it hits our PIX. I want to apply ACLs on the router as well.

As far as router performance, does it matter if I block by IP or specific ports? does it matter??

thanks

Re: ACL question

Depends on the router, the amount of traffic, and the size of the acl. Try and test, but just keep an eye on the CPU and Mem utilization. If it is too much, adjust acordingly. Hope this helps.

Re: ACL question

it's a 3825 with almost a 1GB of memory. I want to block specific IPs or ports. nothing major...

Re: ACL question

Hi,

That should not be a problem provided the memory or CPU resources aren't stretched too thin at this time. If it's not already enabled enable CEF to lessen the impact on CPU usage.
