Using two routers

BlindApex · 03-15-2004, 04:09 PM

Hey, I'm having a LAN party this weekend and there will be about 7 computers. I have a router with 4 ports, but of course we still need 3 more ports. Is it possible to use a second 4-port router (different company) as a hub without any problems?

As long as they are connected with the correct cable you should be ok.

(You don't want to use a crossover cable on both router's uplink port.....)

well....the brand of the router does not matter

if this is a true LAN party....you should only need a hub, not a router, and is a no brainer to configure

better to spend $20 than $50

...just hook up the hub's uplink port into one of the regular ports on the router you already have

there is something you need to know if using two routers. you will be on TWO SEPARATE NETWORKS. Routers do not pass broadcasts (hubs do), so configuration of "routing" is necessary

for example:

routerA = router already established on network
networkA = logical network under routerA (192.168.0.x/24)
routerB = router you are bringing
networkB = logical network under routerB (10.10.10.x/24)

routerA is uplinked to internet
routerB is uplinked to routerA

in order to get networkA to recognize networkB, you need to either update each PC's routing table (cmdline /route add) to tell it which networkA LAN IP (routerB's WAN IP) to go to to get to the networkB network (other PC's)....or

routerA may have it in its management console to add subnetworks...hopefully this is the case

bottom line is to define to networkA how to reach networkB...and that would be routerB's WAN IP (and make sure networkB machines all have routerB's LAN IP as default gateway)...

routerB will then use it's NAT to manage communication with networkA's IP addresses for the networkB computers

...harder to explain in text than it is to show it on a whiteboard =)
