A brief overview of my setup:
I have an ISP provided router which connects via Cat6a to my Mikrotik router via fiber, and then the Mikrotik switch serves as my LAN hub. I have 2 wireless routers connect to the switch, but they are not relevant for this.
I am trying to set up my PC to run servers for various multiplayer games for my friends and I. The issue is that I can get the server up and running perfectly on the LAN, but I am struggling to get it working with WAN addressing. Initially I thought I'd just put in a port-forward on the ISP router to my LAN IP and I'd be good, however, because the LAN IP space I use is not the same network as the ISP's LAN space, it tells me it's invalid. Okay, no big deal, I'll just create a static bidirectional NAT for my PC on the Mikrotik router giving my PC an IP on the ISP LAN space then point it at that.
However, when I do this, I lose connectivity to the router and general internet access - A ping initiated before the rule goes active remains going until I stop and restart it so I'm not totally down when this happens, but I'm not sure what's causing everything else to go haywire. What is the best way to set this up in the Mikrotik environment?
4 X chain=srcnat action=src-nat to-addresses=192.168.0.50 src-address=192.168.100.3 out-interface=bridge1 log=yes log-prefix=""
This is the rule (currently disabled) I am using to NAT
