Things like Teamviewer will run because the connection is started from inside the network over ports 80 and 443. With this, you are actually communicating via the Teamviewer server.
Looking at the WAN settings, that suggests the ISP isn't allocating you an public IP address. That looks like they are using private IPs and then NATing them in their network. Or do you have another router or modem between this one and the ISP?
You might get some information by doing a traceroute from your PC to some external IP. How useful it will be depends on the devices along the way being configured to respond properly.

There is only the ISP modem connected to my router. After that is the cable out to their local switch location.
Maybe a call to tech support at Megacable would find that out for sure and get any port blocking unblocked. Here is a traceroute in Linux to Megacable.com.mx, 200.52.196.125:

Sure awfully busy there for the same domain traceroute to my ISP!
