Oh I see, OK, sounds like you need something that will do a PPP session which some 4G cards will let you do if you put them into serial mode like the Telit LE910 (which I have tried) or the Sierra modules. If you end up with a static or dynamic public IP you can cname the dynamic DNS Mikrotik provides in the router's ip->cloud settings and set the timeout to 60, so you could get at it like bighonchoclient1.elogik.net for example. I kicked the idea around but never tried buying a cheap VPS with a static IP and having the 4G based Mikrotik VPN into it, then on the VPS port forward any ports to services behind the 4G device.

Hi Jason,
OK, I didn't phrase my question very well, what I need is a dongle or card that doesn't provide an extra layer of NAT (as many do) and run an internal DHCP sever so that the routers cellular interface ends up with an IP address like 192.168.x.x but instead passes the public IP directly. This is so I don't end up with a double NAT situation (kind of the equivalent of bridge mode for a DSL modem) and I can access resources (like security systems etc) behind the public IP by configuring the main firewall / router accordingly.

What if you had those routers phone home to a VPN server in your office over 4G? They'd always be in easy reach on private subnet on your LAN and you wouldn't need to worry about public or static IPs for your 4G widget.
I noticed Duxtel configured devices I have bought have a PPTP client set up so if you activate it then Duxtel can peer into the device and assist with any issues.

Does anyone have any advice on a) a decent 4g service that provides a publicly accessible IP address that ports can be forwarded through as well as how to get hold of an unlocked USB dongle which will support the SIM / service?
Or even a provider that provides this on one of their business plans?
If it can be a prepaid plan even better.
I'm looking to use said device as 4G failover on a meraki mx64 security appliance and calling the usual suspects (Optus, telstra) is giving me a headache.
Any advice on what others have done in this scenario would be most appreciated.
