No guides that I've seen, but some Users have reported successful connections.

Though it's accepted the initial contact, the Vigor2600 doesn't like something
about how we have either presented ourselves; our identification or
authentication credentials likely aren't correct, according to the Vigor2600.
You need to check its logs, and find out why it rejected the FreeS/WAN
connection.

If this doesn't help, perhaps you can provide more details in your next post.
Your configuration files, a network diagram representing the machines
you're trying to connect, and any info from the Vigor your can provide.
