Re: VPN Devices

[Patrick Darden <darden () armc org>]

Nortel's Contivity Extranet Switches are fantastic.  Great
interoperability with other VPN devices, especially wrt IPSEC.  Stable
like a rock.  Reliable.  Excellent Client that has caused us No problems
whatsoever.  We are very happy in every way.

Throughput is middle of the road.  We have 3 T-1s so we are not pushing
our switch at all.  IPSEC 3DES Md5, 1000 simultaneous tunnels, 22 branch
offices, 350 doctors, and miscellaneous other mobile employees.

There are other great solutions out there, expecially if you want to roll
your own, but I haven't run into any other packages so well thought out
and that cause so little administrative overhead.
