Hi,

i have a firewall configured on my 1700 series router.

Cisco.com and few other sites are really slow but when I disable ip inspect and ACL from the interface it works great.

I disabled NetFlow too because it slowed down our internet traffic.

1700 is not a powerful box (depends on model), so maybe if you have to many feature enables the CPU is overutilized.
Check "show proc cpu" when all of required features are enabled.

CPU utilization is fine.

Is there a way to exclude cisco.com from ip inspect?
