MRV + multiple subnets

[gbonawitz]

I have read the Tivo.com MRV documentation stating that all the TiVos have to be on the same subnet. Unfortunately, I have multiple subnets (using Linksys routers as pseudo-hubs).
Is there actually any way to use MRV across subnets (e.g. using NAT or something)?

Thanks

It's not clear to me that you need separate subnets. If at all possible, you should run a single subnet. Otherwise, you could try this (http://www.dealdatabase.com/forum/showthread.php?t=52151) tool to bridge the tivo protocol across subnets. You'd have to run it on your routers.

Thanks Jamie for the link. I'll take a look at it.
I don't really need separate subnets; I just spent $$$ on additional routers to both increase the number of available ethernet ports and also make sure I get wireless signal throughout the house.
I'm also trying to just turn off DHCP on all my downstream routers and jack the cable from the WAN ports into the LAN ports instead (and turn off DHCP on those routers).

You should be able to run them all on one subnet. I'm no expert on wireless, but you might need to bridge or relay the wireless access points together if they are all serving the same SSID.

I have two wireless routers.

The cable modem connects directly into the WAN port of the one which has IP x.x.x.1 and the only active DHCP server in the house. I have a 16-port powered switch which connects to one of that router's LAN ports.

Every wired connection in the house hangs off of that switch, including another wireless router in my basement, which is too far away from the first router to get a good signal.

The basement router has a static IP of x.x.x.2 and has DHCP turned off. It has nothing plugged into its WAN port.

Both routers have the same WEP and SSID. One subnet for the whole house, one SSID for the whole house. Works great.

I have basically the same setup as lenoxb locally (24 port cisco switch and an addional wireless router turned into a WAP).

I set up Linksys wrt-54g's (dd-wrt) at my house, dad's, and in-laws. Set my network as 192.168.0, dad as 192.168.1 and in-laws as 192.168.2, then set the subnet mask for all to /16 and did a vpn between them all. All Tivii see each other and mrv fine.

then set the subnet mask for all to /16 and did a vpn between them all.

Can you elaborate? What software are you using to provide the VPN, and what do you mean by "/16"?

[DocTauri]

A /16 is CIDR notation for a network that has the subnet mask of 255.255.0.0 (the first 16 bits are set, therefore, a /24 network has the first 24 bits set, which is 255.255.255.0), it just makes it easier to write the subnet mask. http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing

The VPN is built into the dd-wrt software that I loaded (http://www.dd-wrt.com). So, the Linksys WRT54G routers actually handle the tunnel themselves, no software to load/deal with on local machines. There are various builds of it, one has the vpn software installed. I haven't tried, but I'm sure it's probably a little easier to just use the built in pptp tunnelling capability of dd-wrt.

Also, dd-wrt runs on a lot more than just the WRT54G.

So you got a VPN to connect 3+ Tivos at remote locations and all can play recordings from the others? Thats very interesting. I wonder if this could work between regular Tivo and a DTV Tivo at remote locations.

One question, does the Now Showing list differenciate the recordings, and show which Tivo they are stored on? Or does it just show one large list?

[DocTauri]

I had mine set up as a hub (star topology), they could see me, I could see them, but they couldn't see each other, but it wouldn't be hard to configure a full mesh as you're interested in.

Each tivo appears in the Now Playing list of the others. Clicking that then shows the recordings on that tivo.

Yes, you can go between standard Tivo and DirecTivo as long as all are hacked.
