I'm not sure why you would do any of this.
Most (all?) off the shelf 4G capable routers will accept most (all?) USB 4G dongles. Plug it in, configure the router to use it.
Your router should have all the required NAT and firewalling and so on built in, so you just plug all your ethernet devices into the downstream ports.
Why would you bother with a separate firewall machine? If you want better control of your firewall rules then run openwrt or some such on the router.
It sounds like you're over-complicating the problem.
First, thanks for the replies from both Cory and Mark, as usual though simply writing about the problem gave me a better understanding, and I have a path to follow, a couple of points from the posts................ Cory said, "It sounds like you're over-complicating the problem" Lindsay replies, I understand the setup I now have, all I am effectively doing is removing the 2G usb dongle from the my firewall machine and substituting a 4G modem/router on an ethernet connection to the same box. I am quite happy with how my current firewall works and do not wish to have to take the time to workout how the fire wall rules work on the 4G modem/router, from experience this will likely to take a good deal of time. The current problem is well understood and should not be to difficult to work out. Comment from Marks post, I do not have to worry to much about the NBN, I am currently with Bendigo Telco XL plan, 50gig a month for $60 dollars, Its reliable and fast (on Windows XP anyway, I downloaded Debian 8.9.0 DVD disk 1 in 18 minutes). This is much CHEAPER than my previous mobile broadband plan with 10 times the data. The NBN satelite was $50 for 50gig, so the current setup compares well, support for NBN satellite for both technical and admin was pathetic, where as Bendigo is quite reasonable and readily availible.
