Linksys Router

1. Yes. That's what routers do. :-) However, the "normal" Linksys can only link 2 networks. No more than that.

2. Not me.

how do u configure the router?

please elaborate ... i'm testing one out ...

Connect a PC to one of the LAN ports.
Open a web browser and enter the IP address of the router (usually 192.168.1.1).

Go to http://www.linksys.com for a user guide that has the details.

ya that i know ... but its the routing part i'm not sure how to configure ...

You don't have to do anything to enable routing. It's already configured.

what i mean is 2 networks connected via a linksys router ...

say one is 192.168.1.x and the other is 192.168.5.x ...they must be able to access each other ...

Most Linksys routers are designed to connect an internal network to the outside world with most communications being originated from the internal network.

Because all traffic from the inside to outside is NATed, they're really not meant to connect to internal networks together. Even though you can make certain traffic originate in both directions by using port forwarding, it's not very practical.

Some linksys routers can turn off NAT.  Look for it under advanced settings.  Then you can assign the LAN side one address on the first network like 192.168.1.1 and the WAN side another address on the second network like 192.168.5.1

to make a sure the machines on 192.168.1.x can get to 192.168.5.x you must install a route, like so:

on the 192.168.1.x machines:
   route add 192.168.5.0 mask 255.255.255.0 192.168.1.1
and then on the 192.168.5.x machines:
   route add 192.168.1.0 mask 255.255.255.0 192.168.5.1

those commands are for XP, under unix it is similar (mask is netmask)

I know the BEFSR series can do this, I'm sure others can.

@pattjin

i will try out the "route add" option... what about the WRT series? can it be done on the advance routing setting?
