Problem with remote media gateway

[alexeik]

Hi guys

i have a problem with a remote media gateway. i want to put a mg with gd 3 in service within a customers vpn at a site where ipphone are working. nothing is blocked in the firewall. the gd3 starts to load its binarys but fails with binmg3. within the normal lan at the mainsite the shelf works fine. we traced with wireshark an it seems that a datapacket is sent but the acknowledgement is not received. is there any way to trace within the oxe why?

i put the wireshark screenshots as attachement, cs has 192.168.0.50, gd3 has 192.168 17.103

1st of all check for incidents on CS.

Seems a poor network connection. Maybe a timeout. You are showing only tftp logs

Not really informative.
GD receives 3 or 4 files by tftp. Check in the trace which file's transfer is stopped.
As tftp is very unsafe could be problem in a router configuration. It is clear that on one side ACK is send but not received on the opposite side.
Finding where this packet lost could give a clue who's to blame.

Thats what i thought... but to test we tried to put the mg in severeal lactions of the customer in service. even a location only 10 km away... but the issue is the same... seems that its something with the vpn itself...

... seems that its something with the vpn itself...

But why 41 blocks were sent OK and 42nd failed? May be file size matters?
By the way why such a big file is loaded? If GD is already loaded with the latest binaries it just checks binaries versions on CS and never tries to load them.

Also I would install PC with TFTP-server SW on CS site and try different size file receiving with TFTP-client on a remote site.

yeah i tried the local site after the remote sides so the gd has to load the binarys. But in case of patch or update to another release it should work...
