Solved Using 2nd WRT54GL router to create segregated network with internet ac

[msalton1]

Hello

I have 2 WRT54GL v 1.1 routers. I wish to have router 2 using the same internet connection as Router 1.
I also wish Router 2’s LAN and wireless segregated from Router 1’s LAN and wireless (i.e., Router 2 to share Router 1's internet access only).

I have one cable business account (static IP, if it matters) with one modem (plugged into Router 1's WAN port).

Router #1 (main router running DD-WRT v24-sp2 (07/22/09) mini - build 12548M NEWD Eko):

1. WAN port connected to cable modem
2. Accommodates existing wired NW and an existing wireless NW.
3. Working configuration as expected.
4. LAN Port 4 is configured as a VLAN with an IP of 192.168.2.1, unbridged to LAN

Router #2 (running Linksys stock 4.30.14 Build 5):

Goal: Provide internet access (from Router 1's port 4 vlan) to segregated guest NW for wireless and wired using vlan port (mentioned in point #4 above).


I know I will need to set Router 2's local IP address to 192.168.2.1

I will provide any additional info required.

Thanks for any help,

Salt

Followup:

I was making this a bit too complicated.

The solution:

1. Set router #2's local IP to an out of range IP (i.e., Router #1 LAN port 4 vlan set to 192.168.2.1, set Router #2 local IP to 192.168.3.1)

2. Connect the cable from Router #2 WAN port to Router #1 LAN port 4.

Now works like a champ, and includes a 2nd wireless network.

It also provides a 2nd firewall, creating a greater degree of protection for this 2nd network.

You are simply creating two different subnets here although in most cases it will work better if you connect these two routers LAN port to LAN port rather than LAN to WAN.

Thanks for your comment. How would that work better? Wouldn't LAN to LAN function as an access point or switch (requiring disabling the DHCP server), whereas LAN to WAN would function as a 2nd router?

You can still have DHCP when connected LAN to LAN for the second router and generally speaking you would only use the WAN port to connect a modem.

As long as it works LAN to WAN then lucky you because this normally causes problems.

Sorry, just getting back. Thanks for your input. But I'm not sure lucky is the correct conclusion here, given that it's not an uncommon configuration (LAN to WAN), as a google search will reveal. It isolates the networks and even provides a 2nd firewall for computers connected to the 2nd router. No conflicts, consistent bandwidth, internet access, increased security. A "shield router" of sorts.

I am even able to have a 2nd wireless network in a 200 sq ft space. And the best part is that it's isolated from my main network. I can provide links if you'd like to look into it.
