Now if you go to the status page showing your gateway groups, you’ll see that your primary service (tier 1) is active (in use), and your secondary (tier 2) is ready to take over if there is package loss on the “tier 1” service. I’ve set it to fail-over in the event of packet loss.īack at the routing configuration settings page, set the default gateway to the new fail-over gateway group. Basically the primary service is the “tier 1” service (it will be the default). The following shows the details/settings for the Gateway Group. All settings below what can be seen in this screenshot are empty/unset.Ĭreate a Gateway Group to allow for the fail-over capability. This screenshot shows the Interface settings for the OPT1 (the interface connecting the TP-Link 4G/5G device to the Netgate). This is an explanation, not a walk-through.
The following describes the settings that I’ve used in this test. Use a 4G/5G router that connects via Ethernet for a more reliable outcome. So I’ve concluded that the gamble and time to troubleshoot by trying a USB device is simply not worth it. While I recommend enterprise grade equipment for fail-over gear, this test was purely to examine the difficulty of device configuration required to have the fail-over in place. However, there’s still work to be done to get the fail-over working. No configuration change at all on the Netgate or the TP-LINK at all. I inserted the Optus SIM into the TP-Link 4G/5G device, connected that device to the OPT1 interface on the Netgate 3100 using Ethernet, configured OPT1 on the Netgate for DHCP, and it worked – the OPT1 interface came up. I ended up purchasing a “TP-LINK TL-MR6400 v5 4G/5G router”. However, the “E3372” model is on that list, but the “E3372h” is not. TIP: Netgate have a page listing “known to work” 4G devices. There are ways to deal with this but it’s seriously far more hassle than it’s worth.
The device I received was the E3372h model and that is the “wrong” mode model. That’s because the USB stick can come in two different “modes” determined by the firmware they’re running. I went to my local Optus store and purchased a Huawei E3372 LTE USB sitck and had no luck. The question is, which 4G/5G USB stick will work. If you’re using a USB device for the 4G/5G, then it’s the pfSense drivers that matter.
The model of the Netgate firewall appliance isn’t important. This article discusses my recent experiences with 4G/5G fail-over for a small business running a Netgate 3100 pfSense firewall appliance.
