Applications Behind NAPT That Do Not Require Configuration

The following applications behind NAPT do require any user configuration with the built-in ALG or proxy server running within the 4-Port Router software image.

Protocol (Note 1) Type Port
FTP - File Transfer TCP 21
TALK UDP 517-518
H.323 TCP 1720
IRC TCP 6667
SNMP UDP 161-162
Window’s Media Player (Note 2) UDP 7000-7007
DirectX Game (Note 3) UDP 2300-2400
AOL Instant Messenger (Note 4) TCP 5190
MSN Messenger (Note 4) TCP 1863

  1. All protocols mentioned above are for clients behind the NAPT. If a hosting server is needed, use Port Forwarding.
  2. Window's Media Player uses TCP port 1755 from the player to connect to the server and uses UDP port 7000-7007 to perform the actual streaming of data.
  3. DirectX uses TCP port 47624 from the client behind NAPT to connect to the peer and expects peer to use the UDP port 2300-2400 thereafter.
  4. The AOL and MSN Messenger Proxy Server are required for user-user direct connection during file and image transfer.


Applications Behind NAPT Requiring Application Configuration Change ICQ

The following steps provide a workaround to a problem when using ICQ 's file transfer, Send/Start ICQ chat and PC2PC phone

  1. Under the Connections settings in Preferences, click the User tab, and change it to Using proxy and set the type as "SOCKS 4".
  2. Disconnect and reconnect.
  3. Set the type back to "Not using proxy" and change settings to use the ports you specify. You should now be able to make a permitted connection and have it actually listen. Be sure to disconnect/reconnect after you make every change.
  4. From the DSL modem, use port forwarding to forward the TCP port range chosen in Step 3 to your local machine.
