Routers on same network


Recommended Posts

Here is the question again, as requested, I may get some terminology slightly wrong.

 

So when R1 supports PPPoE in next patch and thus I will be able to connect it to my VDSL modem, here is the question.

 

Modem --> PPPoE --> R1 --> other router

 

If I setup as follows:

 

R1 IP address = 192.168.88.1

2nd Router IP = 192.168.88.2  (WAN port set via static IP; traditionally set to PPPoE protocol)

 

R1 DHCP 192.168.88.100 to 192.168.88.150

2nd DHCP 192.168.88.151 to 192.168.88.199

 

Thus both routers on same IP subnet? Will everything now see each other on the home network or is bridge mode still required? The only bridge mode available to me is via Wifi.

 

Thanks Sim

Hi simjc,

 

Thanks for purchasing the router.

 

Unfortunately you can never use a router to go from same subnet to same subnet. As routing literally means going from one network to another network. What you're proposing is having two different networks although they look similar. So with the proposed set up the LAN devices on the two different networks will not be able to speak to each other.

 

Is it possible to put the other router into bridge mode? If so then that would work ideally. Or you could get a simple switch and connect it to the R1 and achieve the same thing(unless you want wifi).

 

Please let me know what your goal is and I can try help.

My main router has a lot of advanced features on it with gigabit ports and dual band wifi. Unfortunately it doesn't have bridge mode, not for ethernet ports. Looks like it is available for wifi (not played with that yet).

 

So I have a NAS and wanted to stream to my consoles. BUT it also acts as a backup server for my main PC on the traditionaly home network. So it looks like I'll have to investigate the wifi bridge option.

 

However, i've disabled the wifi on the R1 at present because there is no option to stop it broadcasting the SSID. My wifi setup typically is SSID Broadcast off, WPA security, and mac filtering.

 

Prior to the R1 my setup was

 

Modem -> Router

 

Router

  - ethernet port -> Home PC

  - ethernet port -> NAS

  - ethernet port -> Switch -> consoles

 

So now that I have a R1, I've swapped out the switch for the R1 predominantly as PPPoE wasn't available at the time, and it was for my gaming consoles anyway.

 

So going back, predominantly I wanted access to my NAS from consoles. So I could investigate Wifi bridge mode.

 

Now another thought I just had. Is my NAS has a 2nd ethernet port; so either a really long ethernet cable to R1 (prefer not), or some sort of routing via my existing router to R1 using the other ip subnet (but gut is telling me that this is probably a no go without this bridge mode thing at ethernet level)

Right, its really quite a tough one. The only way you could achieve what you want is if one of the routers can be bridged(which they can't) OR you have access to the routing table.

 

What you need is a routing table feature on the R1. Please suggest it in our suggestion forum, if enough people want it, it will bubble up to the top of development list. In the meantime, if you can grab me when I have a spare 20 mins or so I can manually edit routing table for you to achieve what you want.

 

Best,

Iain

Cheers have added feature request.

 

I know you are a busy guy so the help via manually editing routing table is always appreciated. Would I need to connect this direct to modem for you to help?

I have a similar setup to what I think you're looking for, just not with my Netduma yet. In its place right now I have a Linux based router/firewall/NAS. My cable modem connects to the Linux box on its public network interface, and its LAN side interface connects to my switch in the garage. All of my wired devices, consoles, computers, etc. connect in some way to that switch, either directly or via wall jacks to the patch panel to the switch. I then have my Netgear wifi router connected to a port on that switch just on one of its LAN side network ports and all of its firewall/routing functions either disabled or unused. It acts as just a wireless access point that way, providing wifi connectivity to anything in the house that isn't wired. Its LAN ports acts as just another aggregation switch. But very, very important to make sure DHCP is disabled so you're not giving conflicting DHCP reservations! :)

 

I imagine the Netduma will behave the same in that picture as my Linux box, just with more awesome.

 

If you want I can put together a little network diagram, that might explain it better. Once the Netduma arrives I'll be able to test with more than just wild conjecture.

I agree that this is the ideal setup if you are needing more than Wireless N

Very good point about DHCP, also disable UPnP. One of our other users was having issues with opening NAT on his PS4 & Xbone because of two UPnP servers.

I am also interested in this. Right now I have a network down in the shop and one upstairs in the private area. I would like both networks to connect to different routers to different ISPs but I would like all PCs to be accessible. I have one Mac that is on both with two network cards but I don't have double wires in every room.

Please post this as a separate thread, I can go into detail on how you need to wire one to the other and then subnet your PC.

I found on my setup I had to leave UPnP enabled eitherwise I get a moderate NAT.

 

So this is my setup.

 

Modem

Existing Router

- Nat and upnp enabled

- dhcp reserved IP address for netduma r1, 192.168.0.254

Netduma R1

- pretty much default, dhcp enabled 192.168.88.x and upnp enabled

 

Works for me, console gaming wise.
