There are currently several Instant messaging services that support file transfer as well as pc to pc or pc to phone chat. WinRoute Pro has been tested successfully with the following configurations of AOL's instant messenger, Yahoo instant messenger, MSN Messenger, and ICQ.
AIM does not require any specific settings. Use the default connection settings and make sure that you do not specify that you are using a proxy server.
Yahoo IM users must change the login preferences -> connection to "No network detection". All Yahoo IM services should work properly behind NAT with this setting.
MSN Messenger works best using HTTP proxy. Enable WinRoute's proxy on the default port 3128 (In addition to Network Address Translation). The voice features do not work behind NAT.
ICQ works in most cases with the default settings of the latest version. If you have complications using file transfer we recommend using HTTPS proxy found in the preferences -> connections -> server and firewall. Enable WinRoute's proxy on the default port 3128 (In addition to Network Address Translation).
Note: You should not need to map any ports for any of these applications.
