Hi @brwainer & @sphbecker
Thank you for your input, you both appear to have the same answer. While I do understand what you guys are saying, something just does not add up. Firstly, take note this is all home testing and SUPER small scale. One critical key point I missed is that my servers are all VMs. Both solutions you guys provided sounds like my servers need to be physical dedis, well apart from the NAT suggestion. Correct me if I am wrong, since they are VMs, I believe the best solution in this case would be the static NAT 1:1 setup, assuming my consumer router supports it.
But what puzzles me, is that with this approach, I would still need to set a LAN IP to my VM servers, and then use NAT. But when I look at an actual data centre VPS that I work with, and I do a ipconfig/ifconfig command, the IP address is literally the public IP and not the LAN IP. Soooo now this all makes no sense again? Would that imply a data centres VM is directly connected to a switch? Whaaat?
Also, a side question, Is it possible to get multiple IPs on a LTE connection to the router? I guess I would just need a router that supports static NAT?
