I’m based in the UK and using a mobile telco called EE who are generally regarded as having the best 4G LTE service. Using a wAP LTE kit I have LTE pass-through working to a downstream RB2011 over a VLAN and all is good. Here’s the relevant config:
[admin@ACS-LTE1] /interface lte> export
jun/05/2018 09:01:11 by RouterOS 6.42.3
software id = VPGL-JN8Z
model = RouterBOARD wAP R-2nD
serial number = 86C6071C1396
/interface lte
set [ find ] mac-address=AC:FF:FF:00:00:00 name=lte1 pin=1111
/interface lte apn
set [ find default=yes ] apn=everywhere authentication=chap name=EE passthrough-interface=
vlan-LTE passthrough-mac=auto password=secure user=eesecure
EE are using CGNAT and so my public IP is shared and I can’t publish services from inside the LAN. When I attempt to enable IPv6 on the APN…
set [ find default=yes ] apn=everywhere authentication=chap ip-type=ipv4-ipv6 name=EE passthrough-interface=vlan-LTE passthrough-mac=auto
password=secure user=eesecure
… the lte1 interface flaps up and down, and in Winbox, the window for the lte1 interface keeps closing itself, almost as if the whole interface was crashing and being re-added every ten seconds or so.
What am I doing wrong?
