Solved: Cisco 2901 + PAT

FrodoWearinTheRing · ‎06-15-2010

I've been trying to determine what the performance would be like using a Cisco 2901 using PAT. I don't plan on doing anything too fancy (Forwarding a couple of ports and such). I'm looking for something that can do a minimum of 50 Mbps both directions. Does anyone have a suggestion on where I can go and find information on performance under these conditions?

I found the SMARTnet info. It is CON-SNT-2901. --- Many Thanks.

Hi Jonathan,

Performance depends on several factors:

The type of application and its type of traffic
Whether IP addresses are embedded
Exchange and inspection of multiple messages
Source port required
The number of translations
Other applications running at the time
The type of hardware and processor
WAN/LAN Speed and congestion on any of the lines.

You can find the performance numbers from the 2901 without running any services at this URL

You can take these numbers and calculate around 85% to 95% if you were to just run NAT with forwarding a couple of ports.

Regards

Edison
