CPU Load Bcoz of NATing ?

[Bejoy C Alias]

We are planning to connect one of the server in our branch office to the internet for remote access . This branch office is connected to our main office through leased line and we have fixed internet line with 15 public IPs in our main office , one of which we will use for NATing to this branch office server . Anybody can tell me whether there will be any impact on the load of the machine which we will use for NATing ?

Normally, NATing does not generates considerable load on the server, we have have a minimal load on our Internet server. But you should not connect to the Internet a server that is used for storing user data or application data.

Hi Bejoy,

NATing built into Linux Kernel and it wont hog-up your CPU(s). You can go ahead and use NATing.Also make sure you have latest kernel with all patches installed and running properly.

I had a PC (Pentium 3-800 Mhz with 512 MB memory) in my network. It acted as nat server and firewall simultaneously. I had 300 users and about 4 Mb/s bandwidth. There was no any problem and everything was perfect.Nating does not need a fast CPU. However be aware of among od memory on your server.
