[WBEL-users] how to use two networks

[Bikerepairman -]

Hi all,

I'm fairly new to linux to start with. I encounter a small problem.
My computer has two networkcards.(1 on board and one PCI)
I reside on a privete wifi network wich provide internet for me. Call that net A
They granted me six fixed IP aresses  192.168.200.140-145 subnet 255.255.255.0
I have four adreses in use at the moment and everything functions fine.
gateway 192.168.200.2, dns 192.168.200.1 and .2

However, I want to put my two servers on the other network card (let's
say net B)
net B is in the IP range 192.168.210.x on subnet 255.255.255.0
still no problem here.

Now I want my servers to access the internet for updates. I can't get
them to connect to the internet.
the computer/workstation who is bridge, has the IP of
192.168.200.140+192.168.210.1
Who is able/willing to help me with this and if possible with a step
by step how to do.
thanks in advance.
