Hi All,

We are using a RoBox ver 3.3.2 at the office, and I am trying to connect via
Remote VPN to the network and the W2000 network behind it.

At home I have an adsl connection which is asymmetrical, dload 128 Kb,
upload 32 Kb. Using the adsl connection, I can connect to the remote robox,
and get authenticated. I can ping various hosts on the protected side, I can
open a host giving the local IP. I can start to download or upload an item
from either direction, when I monitor the robox via Gbadmin or web interface
remotely the VPN works. But the connection dies after a few minutes. The
dload or upload does not finish. I can start to connect to the servers at
the office via RDP(Remote Desktop-XP) of windows (The servers are w2000 and
have terminal server on them), the frame opens, but the desktop does not
come and the RDP hangs.

I tried to connect to the VPN not using the adsl connection but use the
modem and dial-up (56K bothways). In that case I could use the RDP fully. I
tried uload&dload, they were better, but they did not went all the way
through and the connection was eventually lost without being able to upload
a 3 MB file.

I have Kerio installed in the remote computer, all the filters for the VPN
client is open to the 10 network (office), to the real IP of the remote
connection, and disabling Kerio does not also help.

When I check the logs of the VPN client, I see that Phase I is OK, Phase II
starts, Loads IPSec SA, but after a few minutes of inactivity IPSec is
deleted.

Another user has a cable connection at his home, and he says he has no
problem. So I believe this has a lot to do with connection quality,
timeouts, keep alives, MTU's whatever.

Can you think of a way that we can tweak the client or the robox and have
solid production quality connection?

Regards,
Veli Cigirgan
