 Subject:  Re: [m0n0wall] Traffic shaping in IPSec - alternatives?

Wow..the devil's in the details.  I just bought four wrap boxes and am
configuring m0n0wall this week with the hopes of using trafficshaping for VOIP

Guess i'll get a head start in working on one problem. :)

First question, is it possible to sidestep the problem by using OpenVPN?  I've
read that performance takes a hit with OpenVPN, but i'm not sure by how much.

Second question, probably more lame, is would it be possible to setup two tunnel
endpoints and have a 'high priority' tunnel and a 'low priority' tunnel? 
Routing is a problem here, of course...and it doesn't help if you're
downloading a file from the same box you're RDPing to, but it might at least
give you an option. (This would potentially work in our VoIP situation)

Third question...do you have enough control over the remote end to implement
some form of qos/traffic shaping after the fact?  Presumably anything that does
a reasonable job at the remote end would benefit you at your end...
