SNATMAP server

-

rrac

The SNATMAP service on port 5678 is used to determine the external Internet address of hosts so that connections between iChat users can properly function behind network address translation (NAT). The SNATMAP service simply communicates to clients the Internet address that connected to it. This service runs on an Apple server, but does not send personal information to Apple. When certain iChat AV features are used, this service will be contacted. Blocking this service may cause issues with iChat AV connections with hosts on networks that use NAT.
