RBM11G NL952 Modem, passthrough and admin access

Hardware MikroTik hardware general

Hi all.

Hoping one of you lovely people might be able to assist with an issue I’m facing.
I have LTE internet, currently served by a VN007+ router in passthrough mode in an IP rated enclosure outside hooked up to a pair of parabolics.

I’m upgrading from that router because it doesn’t aggregate all the band’s I need and so purchased an RBM11G and NL952 modem (also got RM500Q) but I’ve only got a single ethernet cable going to the box outside.

Obviously, I need to keep the passthrough mode as my provider serves me a public IP (no cgnat) but would also like to retain access to the admin interface.

I know the modem can do passthrough, I’ve tested it straight through to the ethernet port and it was fine.

I’ve tried various methods, including VLAN APN to ethernet, VLAN APN to bridge and port to ethernet, VLAN APN to ethernet 2 ports and bridge the ports.

Nothing has worked to get passthrough and access to interface on the same ethernet port. I’m really struggling now, I’ve read every piece of material I can find online but most are specific to other routers or specific Mikrotik modem/routers.

Any pointers would really help

TIA

sorry to drag up an old post daz but any chance you can explain in a bit of detail how you managed to do this please?i have the same setup as you including the firmware you posted on another site for the modem, upgrade/downgrade was successful.
i posted here my config…
http://forum.mikrotik.com/t/help-with-lte-passthrough-and-vlan/180460/1
but my issue is every time i set it up and reboot, in quick set the modem doesnt show an internet ip, as soon as i disable the passthrough option the ip shows. ive tried using your above code and editing it to how i think it should be for me but i get an error when importing.

many thanks in advance
