Re: [Guide] Router Mode Setup
This is timely for me - because I need to set something like this up.
Let me see if I've got it right.
Router 1: DHCP from ISP
Static LAN side address of 192.168.3.1/255.255.255.0
Set LAN DHCP to serve addresses only in a small range, say 192.168.3.50 - 59
Set a static IP of 192.168.3.25 (example) for a VOIP ATA.
Router 2: Static WAN IP of 192.168.3.254 (the last available address for router 1), mask of 255.255.255.0
Question: in specifying the WAN side, do the DNS server entries need to be set ? And the DEFAULT GATEWAY should be the LAN side address of ROUTER 1?
Static LAN side address of 192.168.2.2/255.255.255.0
Serving DHCP addresses in 192.168.2.50-99, possible static IPs for connected devices in the 192.168.2.200 range.
Connect LAN port Router 1 to WAN port router 2.
Specify STATIC ROUTE in Router 1 setup
DESTINATION LAN IP - would be the LAN side of Router 2 - in my list above it would be 192.168.2.2/255.255.255.0
DEFAULT GATEWAY would be the WAN side address of Router 2 - in my list above it would be 192.168.3.254
Thanks in advance for any corrections !

quote:
Specify STATIC ROUTE in Router 1 setup
DESTINATION LAN IP - would be the LAN side of Router 2 - in my list above it would be 192.168.2.2/255.255.255.0
DEFAULT GATEWAY would be the WAN side address of Router 2 - in my list above it would be 192.168.3.254
Static routes are specified as: destination mask gateway.
For the destination, you want to use the network address not the IP address of the router. The network address for 192.168.2.2 / 255.255.255.0 is 192.168.2.0/24 (192.168.2.0 / 255.255.255.0)
.
.
With 192.168.2.0/24 you have:
192.168.2.0 = network address
192.168.2.1 = first usable IP address
192.168.2.254 = last usable IP address
192.168.2.255 = broadcast address
Network and broadcast address are not usable.
So static route for router 1 to router 2 = 192.168.2.0 255.255.255.0 192.168.3.254 |

If you just want it to use whatever DNS is set on the router connected to the modem then set it to the LAN IP of the first router and it will just use those. If the DNS on the first router changes, you don't have to make any changes on the other routers DNS settings as long as the LAN IP of the first router doesn't change. You don't have to do it this way though, you could use whatever DNS you like on the routers after the first just like you can on each individual computer connected to either router.  |
