Normal argument "We don't know anything else, so use what we know". After
using FreeS/Wan for a few weeks, you can set it up in 15 minutes too.
FreeS/Wan -> Nortel is iffy... It worked at one point using the older code
(both on Contivity head end and FreeS/Wan) but I don't know about recent.
I'm using Netlock's Contivity client for Linux remote users, but it's not
designed to run as a remote office. I've been debating on testing more
recent stuff, but it's low on my priority list, as I don't ever plan to do
it for any reason other than "see if it works". If someone was really
keen on this, I can do the contivity side easily enough, but I'm not setup
to do the FreeS/Wan side.

I use FreeS/Wan, Nortel and Cisco VPN tech. @ work. The one I have the
least amount of trouble with is the FreeS/Wan. Setup, and forget it.
I've got 4 Contivity 2600's, but I only use them for remote workers, not
remote sites. The Cisco's are used for business partners with the same
attitude as yours... "Cisco or nothing", so I jam them into a little 1720
and then run all the traffic through a firewall.

        Depending on the # of tunnels, probably. See docs/performance for
details.

You've got the main ones... if *you* are stuck supporting it, you'd want
something you know, and don't wanna spend additional $, since you have the
equipment in place already.
