Thanks Jan

I didn't see the link to the repository the first time. I guess i got distracted by the argument going on towards the end of the thread!

I managed to get it connecting to our Microsoft VPN. It looked like it was attempting to authenticate over EAP even with require-mppe-128. I added the following:

refuse-pap
refuse-eap
refuse-chap
refuse-mschap

To guarantee it only used the correct method of authentication.

I also managed to create a tunnel to Giganews VyprVPN service using a slightly different setup.

Now to tackle iproute. Hopefully this will go smoothly!
