HI,

Not finish with me :-)

I solve my problem whith adding a new translation rules from the VM
running the grid (using his private IP) to the VM running the region for
the port 9000. My first transaltion was from "everywhere" to the VM
running the region for the port 9000. But it seems to allow translation
from public IP, not private IP.

But :-)

I'm always not able to connect to my region... I have a message in the
log of Firestorm
doWork: Texture missing from server (404):
http://os-reg.open-dsi.net:9000/CAPS/0288b8e4-57cb-404e-a99d-f587539fa479//?texture_id=cce0f112-878f-4586-a2e2-a8f104bba271

and a few second after

INFO: llmessage/llcircuit.cpp(1193) : dumpResendCountAndReset: Circuit:
88.190.206.74:9000 resent 5 packets

Then a message saying theire is a problem for the connection...

I don't see any error on the region or the grid....

Any ideas ?

Thanks for your help...

Philippe
