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:

    Even if you plug multiple ports into multiple switches to achieve fail-over for one (or more) PC's connected to the switch(es), your switches will need Spanning tree or they will suffer a broadcast storm.
    It's simply not possible with unmanaged "dumb" switches to connect them to each other with multiple connections.

    Alright would a Dell PowerConnect 2724 managed switch do the trick then?

    From what I quickly read it supports link aggregation and VLAN's, so it will probably also support spanning tree.
    I think however that link aggregation (LAG) is the choice you want; it effectively bundles multiple physical connections to 1 logical connection.

    Looking around the forums for "Link Aggregation" seem to come up with needing the switch to feature VLANs - is that correct? If so then I would still need a managed switch in order to pull what I want to pull off. If not then please do explain. [:)]

    No, you don't need both. Link aggregation simply bundles multiple interfaces. UTM supports it and if your switch also supports it, I think it is what you want. VLANS are totally different in that they segregate multiple broadcast domains. Hosts in one VLAN cannot communicate with hosts in another unless a router routes traffic between the VLAN's.
