Hi.

I have just connected to a new Spark ADSL connection and use a Windows VPN connection to connect to a remote office (using PPTP connection).

Whenever I attempt to copy a file across the network (VPN) more than about 500kb in size, the copy stops about 30% of the way in and the connection becomes "dead" (though the VPN connection itself remains connected). The connection doesn't accept data again until I disconnect and reconnect.

I am using a Huawei HG630b and the other end has a Mako Networks box. I don't think it's the Mako end that is the problem as I have not had this issue before from numerous other internet connections.

I have read that it could be a setting within my router that is causing this, though there's nothing obvious that I can change within my HG630b.

Any help is much appreciated.

Thanks.
