PPTP VPN connections fail if "Use default gateway on remote network" is set.

Anybody else experiencing this?

I have one or two PPTP VPN connections which have the "use default gateway"
enabled, as there are multiple networks on the other side. When establishing
these connections, they connect and then disconnect after about 15 to 20
seconds. During this time I can see that the default gateway has not been
set on the interface, and is still showing as 0.0.0.0.

I try the connection many times and it still fails. I then unset the "use
default gateway on remote network" and all is well. I can add a network
route manually and no problems. I have not tried adding a default route to
the network to see if something fails. I should try that I suppose.

Anybody seeing anything similar? This is happening with both networks which
have "use default gateway on remote network" set. One is an Astaro Security
Linux 4 box, the other is a Draytek Vigor 2800 DSL router.

cheers,
Carl

You may want to disable IPv6. Please post back with the result.

De-selecting IPv6 from the connections Networking tab seems to have fixed
it, thanks. I actually have IPv6 disabled through the registry (somewhere..)
already. Strangely, I still see 0.0.0.0 as the default gateway for the
interface when I run ipconfig, but the routing table looks fine when I do
route print.

That doesn't sound quite right, does it Bob? Although it's working, so thank
you!
