How to open ports for eMule and BitTorrent on a Cisco ASA 5505

If you want to use BitTorrent or eMule on pc protected by a Cisco ASA 5505, you have to open some ports on your Cisco firewall in order to download at full speed.

To do this, try these rules in your firewall configuration:

access-list outside_access_in extended permit tcp any interface outside eq XXXX
static (inside,outside) tcp interface XXXX 192.168.1.4 XXXX netmask 255.255.255.255

Replace XXXX with the port number you need to open (e.g. 4662 TCP and 4672 UDP for eMule)

Replace 192.168.1.4 with your pc private lan IP.
