Has anyone had issues with O2 Boost boxes (UK mobile provider for those not familiar) not connecting via a mikrotik router?
we’ve had issues on and off for a long time and cannot seem to get a stable connection.
our Vodafone Suresignal box however has been working fine on the same network. We have swapped out the O2 hardware and the new box is the latest one
Cables have been checked and rechecked
We can see that the boost box has an ip connection and is reaching O2 on port 4500
Quick googling returns link to O2 Boostbox support page where they clearly state:
Most routers are UPnP, but if yours isn’t, you might need to set up port-forwarding on the router’s firewall. The Boostbox needs to access ports:
50 (TCP/IP)
123 (UDP)
500 (UDP)
4500 (UDP)
Depending on complexity of your WAN2LAN setup some of those ports might be used already … 123/udp is a likely candidate (NTP), 4500/udp (IPsec NAT-Traversal [RFC3947]) another one … so when you do set-up dst-nat, you better use src-address (or src-address-list) so that the same ports can be forwarded to some other internal host if needed. But you have to find out correct IP address on the O2 side (perhaps their support can give you a list).
