Can someone give me insight on how to setup UPNP on my RB450G? I need to set it up for Microsoft Server 2012 Essentials Anywhere Access.

This is how I'm doing it.

/ip upnp
set allow-disable-external-interface=no enabled=yes show-dummy-rule=yes
/ip upnp interfaces
add disabled=no forced-external-ip=xx.xx.xx.xx interface=WAN type=external
add disabled=no interface=LAN1 type=internal


Obviously, Replace x.x.x.x with your external static IP. and the interface values with your real interface names.

Once this is done, Devices can UPNP forward ports. Which you will see under IP>Firewall>NAT with a D next to them for dynamic.

Can't you just setup port-forwards instead of UPNP? Just forward the specific ports you need.
