Hello
There was a post by Brian Sommers (the PPP maintainer) about setting up a multi-link PPP server with PPP transported via UDP. This would be a cheap way to aggregate bandwidth.
Things to do :
- set up a PPP link over UDP between your two offices, one on each radio link
- aggregate the two links with MPD (must be in the ports ...)

Subject: Bandwidth aggregation (second try)
(the previous message was accidentaly sent before completion.. that's what
I get for using a different editor than the one I'm used to...)
Hello
I'm hoping that somebody else on this list has had the same problem as I
do, so here goes. We're an ISP with offices in two neighboring cities, one
is in the US, the other one in Mexico. We currently have a couple of
wireless bridges between the offices (breezecom), and the Mexico office
gets its net access from the US side (since Internet access in Mexico at
higher bandwidths is prohibitively expensive).
The problem is the wireless bridges aren't quite performing as good as I'd
like them too. One is a 3mbps model, running at two (because it's proven
to be more reliable at 2), the other is one of the newer 11mbps models.
Currently, each bridge handles a few of the subnets we have, in an attempt
to balance the load between them, however, they're not scaling particularly
well under the heavy traffic.
My question is, is there a way of doing some sort of bandwidth aggregation,
or something that would let me treat 2 or more wireless bridges as a single
"point to point" link? I was toying around with PPPoE, in hopes that I
would be able to do multilink PPPoE, however I don't think that's possible
(yet?) and the PPPoE documentation seems to be a work in progress.
I got a quote for a pair of 'tsunami' 100mbps (45 full-duplex) wireless
bridges and it was close to 30k so I'm hoping to find another solution
using FreeBSD.
Any suggestions welcome
