|Typically, within the router itself you can set it to allow "remote management"|
Personally, I wouldn't do that myself.
When I need to access my SOHO router's management interface remotely, I use RDC to connect to one of my Windows based computers inside my LAN (I have a port forward setup to allow this and RDC is enabled on the target PC) and once I'm connected to that PC, I open a web browser and then connect to the management interface of the router.
Yes, this is effectively the same thing, but more complicated. The reason I do it is security. If someone is port scanning the segment on the network you're on and they get a response from the management interface, they're one password away from breaking into your router and therefore, your LAN.
My Windows password is very complex and I have it set to only 2 failed attempts and you're locked out. This doesn't give a hacker a lot of time, or chances to hack your password and is overall, more secure.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
