LTE passthrough + management on one interface - sanity check

Mon Apr 29, 2024 11:48 pm

Hi

I'm trying to configure my Chateau LTE12 so it passes through lte1 to ether1 and so that I have a VLAN interface (ID 1128 in my case) for management, also on ether1.
The following config seems to work just fine, I just wanted to have it sanity checked whether there are any obvious mistakes or no-gos.

This is literally /export of the whole config:
[admin@MikroTik] > export
# 2024-04-29 22:38:41 by RouterOS 7.14.2
# software id = 6RNW-4179
#
# model = RBD53G-5HacD2HnD
# serial number = 
/interface wireless
set [ find default-name=wlan1 ] ssid=MikroTik
set [ find default-name=wlan2 ] ssid=MikroTik
/interface lte
set [ find default-name=lte1 ] allow-roaming=no band="" sms-read=no
/interface vlan
add interface=ether1 name=VLAN1128-MGMT vlan-id=1128
/interface list
add name=MGMT
/interface lte apn
set [ find default=yes ] passthrough-interface=ether1 passthrough-mac=auto
/interface wireless security-profiles
set [ find default=yes ] supplicant-identity=MikroTik
/ip hotspot profile
set [ find default=yes ] html-directory=hotspot
/ipv6 settings
set disable-ipv6=yes
/interface list member
add interface=VLAN1128-MGMT list=MGMT
/ip dhcp-client
add interface=VLAN1128-MGMT
/system clock
set time-zone-name=Europe/Vienna
/system note
set show-at-login=no
/system routerboard settings
set auto-upgrade=yes
/tool mac-server
set allowed-interface-list=MGMT
/tool mac-server mac-winbox
set allowed-interface-list=MGMT
/tool sms
set port=lte1 receive-enabled=yes
Can it be done like this?
Thanks!

I'm using a similar setup and it works just fine. However with some differences:
- Management is for me the plain Ethernet link, data is on VLAN. If something goes wrong it must be possible to plug in a computer and access the LTE router. I don't think that would work on a pass-through interface, even for MAC-telnet.
- I have a static /30 IPv4 prefix assigned on the link, no DHCP. Management of the LTE device must be possible what I do to the LAN configuration.
- The LTE pass-through router has a default gateway pointing to the main router of the network, so that the LTE device can get firmware updates and be managed from any device in any of LAN subnets. I suppose you using DHCP have it too, but again: no DHCP for me, so I've configured it explicitly.
