Good day,
This question is also posted at the oracle.com communities.
My Sun Ray 2 DTU sits behind a NAT agent. It is therefore pointless for my
Sun Ray Server 4.1 to do what it is currently doing, specifically: it is
trying to open the ALP UDP connection, rather than wait for the DTU to open
it. Can anyone tell me how to convince the server to wait for the UDP
connection - not initiate it? Another server that I manage does not pose the
same problem with the DTU - it waits for the connection. Both the servers
have the same authentication policy: -r card -z pseudo -k both
Below, I have posted the snoop output, for both the un-complying server
(posted first) and the complying server.
Cheers,
Etienne
