oh i guess you are. I can almost promise it the routing. Need to open some ports, specifically the PINGing ports IIRC. i don't know, Im the DMZ host on my router so i never mess with it.
Something I don't understand about DSL.

Two Factor Authentication is now available on BeyondUnreal Forums. To configure it, visit your Profile and look for the "Two Step Verification" option on the left side. We can send codes via email (may be slower) or you can set up any TOTP Authenticator app on your phone (Authy, Google Authenticator, etc) to deliver codes. It is highly recommended that you configure this to keep your account safe.

You offered only one word of assistance. That will get you one pence. You'll have to earn the other pence.

FYI, ping is at the IP layer. It never reaches the application layer, thus it dosn't have a port.

TCP/IP doesn't exactly follow the OSI model and the layers are rather loosely defined. The network layer in TCP/IP would be roughly the network/datalink/physical layers in OSI. These layers basically figure out how to send data over the physical medium. The IP layer handles IP packets (who would have thought?). This is where the network stack handles ping packets. Above this is the application layer (TCP/UDP sockets). Ports associate packets with a socket. Ping packets never reach this point.

Ahh, that's right... I remember now. Heh, I didn't study the TCP/IP model as well as I should have during CISCO Academy 
Thanks for the refresher :tup:
