Connecting two routers
Posted on 2006-07-05
I struggling to understand what goes on when I connect two routers.
The first router (R1) is a non-wireless router, connected to a modem, then on to my ISP. It has four LAN connectors, and handles DHCP to whatever plugs into them. I connected one of these LAN ports to the the WAN port of a RangeMax router (R2), which will serve as an access point. The reason I'm using a router and not a switch for this is because this router was the only powerful transceiver I could get my hands on.
R2 will have a few wireless PCs connected to it from time to time.
R2 is getting an "Internet" IP address from the DHCP of R1 (192.168.0.6) Mysteriously, these appeared in the static ip address boxes, and the "Use Static IP address" is checked!
R2 is getting the gateway information from R1 (192.168.0.1). Again, this has appeared in the static ip address boxes.
SO, these two IP addresses, together with the subnet mask, have appeared automatically, even though I opted to use static addresses here. So here begins my confusion.
to go on....
R2 has fixed DNS server names (my ISP's)
R2 also has a fixed LAN IP address, 192.168.2.1, that I put in it.
R2 also has a fixed subnet mask that I put in it.
This I follow.
I requested that R2 does not do any DHCP - is this correct? I thought that R1 would deal out IP addresses to the clients connected to R2, but, when I check those R2 clients, the IP address range is clearly coming from R2! How can this be, and is this correct? (Remember, the R2 is instructed not to do DHCP).
Finally, I set RIP to "Both" and used RIP_1
Some advice / help appreciated. Please don't be too technical.
