Turning extra 6 LANS into "router" like links (UPDATE disconnects in 13-15 minutes loops)

DavidG1

Hey all I just finished up setting up the UTM 9 Home edition and I currently have it up and running with eth0 as the WAN and eth1 as the LAN. However, my motherboard has a total of 8 Ethernet ports (though 2 are being used for WAN and LAN out of the 8 - so 6 Ethernet ports open).

What I would like to do is be able to use those Ethernet ports (eth1-eth7) as a type of "router" switch. In other words, make them like a router has on the back of it where you can hook up more devices to it. I will be hooking them all into a 24 port switch (non-manage) and I would like to be able to unplug one of those eth1-7 plugs and still be able to get onto the internet with the other Ethernet ports as "backup" if possible.

So as an example of the above:

I have eth1 as the LAN and eth2. Both are plugged into the 24 port switch. I also have a PC hooked to that same 24 port switch. The PC has access to the internet and can surf the internet. However, lets say I need to unplug eth1 for a reason but still want the PC to have internet. I am wanting eth2 to take over to continue to feed the PC the internet while eth1 is unplugged.

Hopefully this can be done so I don't waste money buying a motherboard with a lot of extra Ethernet ports! [:)]

Thanks for your time.

David

UPDATE:

Hey all I have decided to track when and how long my current UTM 9 setup is messing up. Here is the flow:

Disconnects internet access (LAN and WIFI) every 13-15 minutes -> Takes about 25-30 seconds to come back -> repeats

It seems to be a constant 13-15min intervals when it disconnects and also a constant 25-30 seconds of nothing before it comes back online.

What setting(s) should I look for in my control panel in order to make sure I don't have a setting disabled or set up incorrectly for this type of issue to happen? Since I am using LAG and the netgear, how can I test to make sure its not the Netgear doing this? Is it the issue with this causing a broadcast storm?

And during the downtown this is what it shows now for the ping:

    Looking around the forums for "Link Aggregation" seem to come up with needing the switch to feature VLANs - is that correct
    Negative.  VLANs and Link Aggregation are two very different things.  You need a managed switch that supports IEEE 802.1aq LAG.  As mentioned it'll also need Spanning Tree functionality to avoid routing loops and broadcast storms.  The NICs in your UTM box would also need to support LAG/Teaming.  To be honest, I think you're making things more complicated than they need to be.  If you want to plug  changes needed.your switch into a different port, just log into WebAdmin, edit your interface, change the Hardware assignment, then switch the cable over.  Failing that, as Andrew mentioned, bridge two or more interfaces together.  As long as only one is plugged into the switch at a time, you can switch between them with no other changes needed.
