CCTV Router 2 Subnet of router 1?

Recommended Posts

I have installed a 4 Axis camera system with Aver DVR in an attorney's office, and have all connections working on my router. The office has a Linksys WRT54GS, with DHCP turned off. All in-house computers have fixed IP's.

 

The office network guy set it up this way. The 2 routers are set up on different subnets, Router 1 = 192.168.1.1, and the video router = 192.168.10.1 He assigned my router (Trendnet TEW652BRP V2.00.32) on his network to: 192.168.1.222 and said that should go into my routers WAN, He then did a DMZ on router 1 192.168.1.222 for my Routers WAN

This didn't work!

He doesn't want to just make the connection of my equipment directly and have my system enter his network as a switch, but keep my router "Separate" from his network.

 

How is it done so it works please, I appreciate your insight. I know this may not be as secure, but this is the only option for now according to this network guy. The client is upgrading their net services soon so I'll have my own IP in a month or so, but the boss wants to see his video on his iphone sooner. Thanks

I'm surprised that you're running your office on a WRT54 box, even with upgraded software like DD-WRT it's really still a cheap plastic box, one suggestion is to setup a small Atom based PC or grab an old box that isn't in use anymore so long as it has a working NIC and can have a 2nd NIC added to it and run Untangle as your firewall.

 

As for the actual situation you're attempting to do, it's best to setup the network using VLAN's (Virtual Lans) and bridge them over but in re-reading your setup, don't plug into the WAN port of your router, plug into an open LAN port or setup the WAN port (if you can manage the box) as a LAN port and make sure that DHCP is turned off as it's being assigned on the equipment or from another server.

 

My network is comparable to a corporate network to run a simple SoHo with a number of switches, access points and VLAN's and I'll be the first to admit it's overly complicated but I have a hunch that if you move the cable from the WAN port to a LAN port, you'll be up and running.

I'd just use a switch for the cameras... the office network guy doesn't know his stuff if he thinks this is going to be a problem.
