more than one tunnel on a gnatbox?

[Stuart Birchall]

Hi,
several people have been asking whether or not it's possible to use several
gnatboxes to inter-connect remote sites via Internet VPN. I'm familiar in
configuring Gnatboxes on a site-to-site, point-to-point basis, but I'm not
sure about multiple connections. How easy is this to set up?
Thanks for any advice.
Stu
