on bit comet
Im new to PEER to peer and i think i need to ublock this router below for a faster download or upload

this blocked by my firewall. How can

Listen Port of TCP:65534 (Blocked by Firewall/Router)FIRSTLY what firewall are you running? e.g. Windows Firewall on Windows 7 ...
What router do you have? e.g Netgear DG834G

Generally speaking the FIRST time you run a program such as bitcomet after installing it your firewall software will pop up asking if you want to allow it access to thee internet, and so long as you click yes the ports that are needed get allowed through the firewall on your PC and directed to the program.

Depending on who you are with for the internet, i.e. who is your ISP (BT, Talktalk), the ISP may themselves block traffic on ports known for peer2peer or other filesharing.

Very rarely do you have to add ports to the firewall in the router because;

Most routers are set that once a program runs such as Bitcomet
The program makes external internet activity on the need ports such as the LISTENING port '65534' the router allows this out and in turn directs traffic that comes back on that port back to the originating PC or laptop.

Either WAY give us a few more details and we should be able to help.
