[Opensim-users] Opensim 0.6.6 release standalone hangs at 'Waiting for Region Handshake'

[clive gould]

The main problem we have encountered with internal and external access
relates to the region handshake failing. It appears that the client
initially uses the address associated with the client Login URI box
(FQDN accepted here) to connect to the server and exchange
authentication information using the TCP protocol.

During login, when the client reaches the point of the region
handshake it suddenly switches from using TCP to UDP. It also switches
to using a return IP address supplied by the server (which the server
has derived from Regions.ini - FQDN NOT accepted here).

This change of address for the server can easily result in the region
handshake failing if the client cannot reach the server on the new
address. The client initiates the region handshake by sending the UDP
packet(s) and times out if these packets are undeliverable.
