Hello - Ubuntu Linux Newbie Here.

The situation: Building a Camera DVR system for my office.
Ubuntu 12.04 on a repurposed server running Ubiquity "Airvision" DVR system.

eth0 is connected to LAN network (10.0.0.0/24) and it all works fine with a couple of test cameras also on the 10.0.0.0/24 network.

I want to create a different network (192.168.0.0/24) that the cameras will live on to keep all the camera feeds off the regular LAN and to keep that network separate and private.

How can I setup the server (it has dual NICS) so that the "Airvision" server can see all the cameras on 192.168.0.0/24, and at the same time be accessible from the LAN side 10.0.0.0/24

The LAN connection to the server is via the eth0 NIC
The cameras will connect to the server via eth1 NIC

I assume it requires eth1 to be static with a 192.168.0.X address, and then some settings to allow routing across the two networks so that the Airvision software can see the cameras and be accessed from the LAN, but I don't want to make the camera network visible to all the 10.0.0.0/24 users.

Thanks for any help and advice!

I'm not an expert here, but have you tried it yet? I can't imagine you'd need to do anything more than assign each interface an IP on the respective network, configure your ip routes to default to the one with internet access, and go.

The server software listens on a port, not on an IP, so it should be able to accept incoming requests from either network.

I have several servers that are split onto two subnets, and I didn't have to do any more than what I described in my first paragraph. eth0 has a static IP on subnet 1, eth1 has a static IP on subnet 2, and ip route is configured to default to subnet 1 (subnet 2 has no internet access). I can access any server daemon on the machine (ssh, ftp, httpd, etc) from either subnet by using the proper address.

Thanks for the info suicidaleggroll.

Any chance you can provide more detail (real newbie here), such as the gateway settings for the second NIC, plus the "ip route" setup.

Appreciate the help!

The gateway settings are no different than on a single NIC setup

eth0:
eth1:
And for ip route I just made sure that the default was eth0 (for some reason it was defaulting to eth1 after I set up both interfaces)
