Mikrotik 4G LTE bridge mode?

Will new Mikrotik SXT LTE work in bridge mode?
In my place, it is possible to get excess of 100Mb DL speed.
That's why I wondered as an alternative to something such issues with a combination of:
RB912UAG-5HPnD, (with pci-e and SIM slot)
Huawei ME909s-120 (mini pci-e, CAT4, 150/50 Mb)
Is a good combination? Will it work bridge mode?
Or is this also the PPP mode, the speed is lower?
Or maybe something else?

I am interested to know this too.
If the SXT LTE can bridge the LTE interface to ether1, we would be able to connect it to a RouterBoard inside the building and have all the IP configuration on the indoors RB. All the SXT LTE units could be sent out with an identical config, and it would simplify installs for us significantly.

Yes i hope to see this feature as soon as possible or any create work-around. Maybe somebody will be motivated doing this -->

Nope, you can't. Bridging LTE is an upcoming feature of 6.41 but SXT LTE is not going to be supported:

so what kind of sense does this have then?
i am having a constellation at home of
1x SXT LTE
1x RB922UAGS-5HPacD
config. of the SXTLTE:
[SXTWLTE-border] /ip firewall> ex
# feb/23/2018 17:23:16 by RouterOS 6.41.1
# software id = xxxx-xxxx
#
# model = RouterBOARD SXT LTE 3-7
# serial number = 7xxxxxxxxxxx
/ip firewall filter
add action=accept chain=input connection-state=established,related in-interface=lte01
add action=drop chain=input connection-state=new in-interface=lte01
add action=drop chain=input connection-state=untracked disabled=yes in-interface=lte01
add action=accept chain=input in-interface=ether1
add action=fasttrack-connection chain=forward connection-state=established,related
add action=accept chain=forward connection-state=established,related
add action=accept chain=forward in-interface=ether1 out-interface=lte01
/ip firewall nat
add action=dst-nat chain=dstnat in-interface=lte01 to-addresses=10.254.0.2
add action=masquerade chain=srcnat out-interface=lte01 src-address=192.168.1.0/24
add action=masquerade chain=srcnat out-interface=lte01 src-address=10.20.30.0/24
add action=masquerade chain=srcnat out-interface=lte01 src-address=10.254.0.2
/ip firewall service-port
set ftp disabled=yes
set tftp disabled=yes
set irc disabled=yes
set h323 disabled=yes
set sip disabled=yes
set pptp disabled=yes
set udplite disabled=yes
set sctp disabled=yes
rOS 6.41.2 ...
still not able to bridge ether1 with lte1 on SXTLTE!
i would love to handle all kind of stuff again on the RB and rather have the SXT
only for LTE connection (plan is to install the SXT outside pointing to the LTE Cell Tower)

I've been trying to get hold of a wAP LTE Kit, but no luck yet. I believe it can do bridging, but I can't find a reference now.
Here is the current list:
https://wiki.mikrotik.com/wiki/Manual:P ... lar_modems Look for the Passthrough Support: Y
SXT LTE is not going to be supported. I believe the reason is the chipset it is based on.

but why? is it a software limitation or is it because of hardware boundaries?? this is a pitty, because the SXT LTE would be THE perfect device for that!
so you think this is a hardware issue?

I don't know, but I believe there is some good reason.
Yeah, I like the SXT LTE as well. However, wAP LTE Kit looks like an equally good device at a comparable price. If I only get my hands on one, I may switch my favorite. My plan is to attach an external, directional antenna to it.

Just posted the SAME question today. This is going on for years with no resolution? That's just nuts.

That will not work for the SXTLTE3-7 which is what this discussion is about, the original SXTLTE
