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
I've done this a couple of times with sunrays at home,
I am not sure if the solutions were correct by the books -
but they did work:
1) One router (DLink DIR-655) allowed to publish a "DMZ
host", so that all incoming packets from WAN were NATed
to the same ports of the designated LAN IP - SunRay DTU.
2) Later we played with SunRay2 VPNs and set that up.
I believe this way ALU is no longer dependant on NAT,
as long as the VPN channel works ok - ALU connects
servers to DTUs both ways.
HTH,
