Need router to accept traffic from two sources

I need my 3com router to accept traffic from the following: 1) addresses and 2) a single address on a network.  But here's the part that's throwing me off, the LAN side of the 3com router is ALREADY on the and the WAN side is ALREADY on the network.  As it is now, the router is handling traffic from the network just fine, but it's not allowing through traffic from the network (obviously, because the LAN side is on a different subnet than the traffic it's trying to allow).  I was told that I need to add a static route to allow the 68.255.169.x traffic to access the LAN side of the router (this router only has a web interface with the following fields: destination network, subnet mask, gateway address, and a drop down with the choices "LAN" or "WAN").  Could someone please tell me what to enter for each field?  Also, as plainly as possible, could someone explain what is meant by destination address, gateway address, and "LAN" and "WAN" as it applies here to static routes?  Thanks much.

You shouldn't need static routes as the two networks are on the same router.  Routing between the LAN and WAN interfaces should be automatic.  What are you trying to do and what is not working?

The router doesn't need a static route for a directly connected network. It already knows about those since it's directly connected to them.

As fas as adding a static route, the fields are:

Destination address - The IP address of the network/device you need to get to.
Subnet mask - The mask used with the address above.
Gateway address - The IP address of the next device (router) you would go through to get to the destination.
LAN/WAN - Which interface you will go out of while going to the destination.

But if a device is unable to get to a device I suggest verifying your end station IP addresses, masks and default gateways.
