I strongly disagree. There are many reasons for this. Two of which are increased throughoutput and redundancy. The primary problem is that you need to make sure outgoing data for a connection is using the same line as the incoming connection. If the majority to all connections are outgoing and both lines use NAT and have unique IP addresses, it's simpler to setup. If you have incoming connections as well, either only one of the two lines will be used or you'll need BGP or some kind of static route setup by the two ISPs. For an internet cafe, most connections will probably be outgoing so it won't be a problem. I have done this with a Linux router and using Comcast Cable and SpiritOne DSL. We had all incoming connections use DSL and outgoing connections use either line. We balanced them by internal IP addresses, but there might be more sophisticated methods. I do not know what support FreeBSD has for this kind of routing though. At the very minimum, you could get redundancy for outgoing connections by switching the route to use the other line when the first one fails. >=20 > Note that Steven's scenario below is for 2 circuits that > both start at a single entity, and both end at a single entity. >=20 > Ted >=20 >=20 > >-----Original Message----- > >From: owner-freebsd-questions@freebsd.org > >[mailto:owner-freebsd-questions@freebsd.org]On Behalf Of Yance Kowara > >Sent: Sunday, December 11, 2005 7:03 PM > >To: freebsd-questions@freebsd.org > >Subject: FreeBSD router two DSL connections > > > > > >Hi all, > > > >I am trying to figure out if *BSD can achieve this: > > > >I have two DSL connections to play with, and I would > >like to configure a *BSD router that can combine the > >two DSLs together. > > > >There is a howto at > >http://stevenfettig.com/mythoughts/archives/000173.php > > > >But it concerns OpenBSD and it was for a T1 connection > >using a dual T1 card.
