dual gateway with routing issues and tinc-up and host-up scripts for windows clients?

[Jelle de Jong]

Hello everybody,

I am doing some test with TINC and Windows 7 and I am having some issues
with routing. (see attachment for the client configuration)

The set-up I configured uses DHCP over the TINC tunnel and the Windows
guests ends up with two gateways (one from its own network and one from
the TINC network).

The problem is that traffic when browsing the internet should go over
the TINC tunnel as well and now it is currently split.

I thought I would change the TINC gateways metric to be lower then the
gateway from the standard Windows client, but this does not provide a
stable solution as the clients internet stops working completely from
time to time.

How can I execute a dynamic script under Windows when the TINC tunnel
comes up? To say execute the following command: route ADD 0.0.0.0 MASK
255.255.252.0 192.168.200.1 METRIC 5 IF 24

Any advice would be much appreciated.

Kind regards,

Jelle de Jong
