Can someone help me configure my new RB750GL to be accessed remote over the web? 
I’m new here and need help. Thanks!
ensure the service is active.
/ip service enable www
set your firewall to allow it, ether1 as an example in this case (tip: maybe restrict by source ip for extra security)
add chain=input comment="Allow Web" dst-port=80 in-interface=ether1 protocol=tcp
make sure you have a strong password !
In addition to strong password, etc. change the port to something else than 80 or it will be getting probed constantly by scumbags trying to get in.
If they don’t know where to look, they can’t find you.
i will try that, thank you!
Look at port knocking. I do a 3 knock combo. Basically you try to connect ipaddress:port1, ip:port2, ip:port3, ip:80, each attempt adds your source address to a list, port2 only listens to sec addresses on port1’s list etc etc. drop all other packets to port 80
