Hi, welcome to the forum
the setup should be the same as with vanilla server, if you can run it and connect to it, then running MCServer instead of the vanilla server should work for you without any more changes.
You seem to know the IP address; just in case you wanted to verify it, in windows, press Win+R keys together, this will show the "Run" dialog box, enter "cmd" (without quotes) as the command, press ok, a black console window should open. Type in "ipconfig /all" and it should list all your network adapters together with their IP addresses. In linux, you should use the "ifconfig" command with similar results. If you have a home network that connects to the internet via a single point (router, cable modem etc.) you most probably have NAT enabled on that device and all the computers are in a single LAN network. IP you get this way from external sites, such as google.com or whatismyip.com is the outer IP address of the router, not the inner address of the computer. In such case, your IP should be something like 192.168.x.y or 172.16.x.y or 10.x.y.z ( http://en.wikipedia.org/wiki/IP_address#..._addresses )
To connect to the server, you should enter just this IP address in the "Server address" field in Minecraft. There's no need to specify the port, because it uses the 25565 port by default. If you set your server to a different port (you will know about this, the server lists the ports it's running on when it starts up), then you'll have to add the port number after the colon.
You do not need to modify any settings on your router unless you want to make the server visible from the outer internet. The router should automatically pass through local traffic between the LAN computers without any problems.
To use the webadmin interface, you need to configure the allowed users first. This is done by editing the "webadmin.ini" file next to the server. It should contain all the instructions you need; basically you need to add a section "[user:<username>]" containing a value "Password=<MyPassword>". Note that this file is whitespace-sensitive, you must not add any spaces or tabs in the values.
