My biggest struggle with my Mikrotik was discovering how much consumer grade routers do behind the scenes automagically that commercial grade routers will not.

My biggest struggle with my Mikrotik was discovering how much consumer grade routers do behind the scenes automagically that commercial grade routers will not. For instance, I wanted working NAT reflection and since my external IPv4 address is dynamic I wanted to construct a static ruleset that didn't specifically reference it. The solution there required me to exclude traffic destined for my LAN address range in my dnat forwarding rules to get it working properly. Fun stuff.
