The specs say it has one 10/100 Ethernet port, so surely it's just a modem. Perhaps that 10/100 port is the reason it only supports up to 100Mbps.

If using with Three I'm not sure it will work, doesn't Three use 800 Mhz frequency? Note, I could well be wrong on this.

They all use the following frequencies:

800mhz = Band 20
1800mhz = Band 3
2100mhz = Band 1

Vodafone and EE also have
2600mhz = Band 7

O2 also has
2300mhz = Band 40

To confirm check Ofcom. The networks have permission to run 4G (LTE) on any of the frequencies they own. Future spectrum auctions are due.

The Specs for the SXT LTE state the following.

In reference to mikrotik.com/product/RBSXTLTE3-7#fndtn-specifications:

LTE FDD bands 3 (1800MHz) / 7 (2600MHz)

So it appears not cover 800Mhz or 2300Mhz

That's the old model, Mikrotik naming of these seems rather odd, but that's the old one that had a single 100M port, only worked on 4G / LTE (couldn't fall down to 3G) only worked on bands 3 & 7 and was a category 3 device (100M down, 50M up).

The newer one https://mikrotik.com/product/sxt_lte_kit can fall all the way back to 2G, is an LTE category 4 device (150M down, 50M up) does POE pass through on it's 2nd 100M port (no, I have no idea why they didn't make it a gigabit port) and most importantly, works on LTE bands 1, 2, 3, 7, 8, 20 (800Mhz) 38 & 40 (2300Mhz).

Mikrotik do also make this beast, which the OP may want to consider: https://mikrotik.com/product/lhg_lte_kit

I've got the SXT LTE kit (the newer product), it is my understanding that it can't operate in bridge mode and that it will never be able to.

*this might be incorrect, check the following messages in the thread*

Bridging � spanning tree protocol (STP, RSTP), bridge firewall and MAC natting.

Am I misunderstanding that, copied from the OS Features on this page of the RouterOS software manual linked here?

CGNAT not an issue on Three if you use 3internet as the APN.

I am using HomeFi router with a DMZ connection to WAN port on my RT-AC87U router.

Port forwarding works fine although I've now moved to OpenVPN due to security issues on some of the IPcameras etc..

Using DDNS to get around Fixed IP issues as IP is refreshed sometime in the early hours every day.

RouterOS supports bridging, but only on some of their hardware.

They list the support here:

https://wiki.mikrotik.com/wiki/Manual:Peripherals#Ce...

However, reading it again it seems the R11e-LTE (which I believe is the LTE card they use in the SXT LTE kit) is listed as supporting passthru. So I need to do some more investigation as to whether it can be made to work with the SXT LTE kit or not.
