Port keeps closed, speed slow

[bugmenot]

I have setup a static IP as described on this site.

I have setup port forwarding from portforwarding.com instructions.

Yet, port 2020 remains 'closed'. I have also tried disabling the firewall of the Zyxel D1A, and even my local PC Comodo 2.4 firewall. I'm using Windows 2000.

Could someone with a similar setup please assist in bursting it open? It's very annoying....

Recheck that http://forum.utorrent.com/viewtopic.php?pid=289822#p289822 for Comodo

and use an other port that 2020, best in the range of 49152 to 65535 acc. to http://www.iana.org/assignments/port-numbers

Thank you for your reply.

After:

- Changing Zyxel NAT port to 55555 and also entering 55555 in the 'Port Translation' fields,

- Swapping the Source-Destination ports in Comodo 2.4.18.184 using port 55555,

- Turning off the Zyxel firewall;

Speed is now up to par.
