Bonding means you must connect two devices and from this second device receive internet. Like: SXTR + hAP ac2

You must

• disable PoE on Ether2
• connect via mac address, enable romon.
• delete bridge port like ether1,ether2 and bridge itself
• create bonding
• Add IP + DHCP Server + NAT …. OR Passthrough

My experience:

• Install routerOS on VM on my laptop
• get temporary 24 hour license
• enable romon on 4G device
• connect to routerOS on vm, romon onto 4G devie, make changes as detailed above
• bonding by round robin works best as it alternates packets

https://wiki.mikrotik.com/wiki/Manual:Interface/LTE#Passthrough_Example

To configure the Passthrough on ether1:

[admin@MikroTik] > /interface lte apn add apn=apn1 passthrough-interface=ether1
[admin@MikroTik] > /interface lte set lte1 apn-profiles=apn1

To configure the Passthrough on ether1 host 00:0C:42:03:06:AB:

[admin@MikroTik] > /interface lte apn add apn=apn1 passthrough-interface=ether1 passthrough-mac=00:0C:42:03:06:AB
[admin@MikroTik] > /interface lte set lte1 apn-profiles=apn1

To configure multiple APNs on ether1 and ether2:

[admin@MikroTik] > /interface lte apn add apn=apn1 passthrough-interface=ether1
[admin@MikroTik] > /interface lte apn add apn=apn2 passthrough-interface=ether2
[admin@MikroTik] > /interface lte set lte1 apn-profiles=apn1,apn2

To configure multiple APNs with the same APN for different interfaces:

[admin@MikroTik] > /interface lte apn add name=interface1 apn=apn1
[admin@MikroTik] > /interface lte apn add name=interface2 apn=apn1 passthrough-interface=ether1
[admin@MikroTik] > /interface lte set lte1 apn-profiles=interface1
[admin@MikroTik] > /interface lte set lte2 apn-profiles=interface2
