Weird behaviour between Windows Vista & Windows 7 VPN - can anyone help?

[Alan S. Lawee]

Windows 7 & Vista did not allow me to assign the same IP address to both the
LAN & TAP adapters - even if I try to force it, the TAP adapter is set to a
blank IP address.  That is why I used .207 & .208;  the question I had is
whether the 'Home' PC should be on 192.168.1.208 or 192.168.2.208;  I'm
thinking now that it should be 1.208, so that it will see the network at the
office.

All I really need to do is to have the two PCs see each other.  For the Home
PC to see the rest of the office LAN would be a bonus, but not really
necessary.

I will try to regenerate the security keys - hopefully that will resolve the
'Bogus data' message.

I'll let you know tomorrow how things go.

Thanks again & best regards,
Alan

You can use 192.168.1.7 on the TAP adapter at Office and 192.168.2.8 at
Home, there is no need to have a different address than on the LAN
interface.

That means something is wrong with the public/private keys. To be sure, just
remove them completely, both from the host config files, and delete
rsa_key.priv, and then create them again.

If you use a firewall, you have to ensure that it allows access from the TAP
adapter as well.

It was not clear from your first mail, but if you want the computer at Home
to be able to see all the other machines at the Office, then you need to
have a completely different setup.
