Due to the limitations of the BPL devices we use in our ISP backbone, we have to handle Network Address Translations centrally. At our perimeter point, we need a router that can
1)Terminate MetroEthernet at outside FastEthernet interface (Easy)
2)Perform well in router-on-a-stick scenario for 32 VLANs at inside interface(**)
3)Handle Network Address Translations for about 1000+ clients(**)
4)Perform IPS and Firewall
** ->I detached a Cisco 2651XM with latest IOS, configured as router-on-a-stick, router from a location where 500+ NATs were occuring and CPU was hitting %100 and rendering the device unresponsive. This issue might be occuring because of these ** mentioned points above. I attached a simple device called Netasq that runs on FreeBSD platform, configured same, and it performs great with %4 CPU. Maybe it was a bug, I called TAC but it was EOL, opened a topic in NetPro but no solution.
Waiting for suggestions
