Multiple tun loadbalancing question

If three different providers, then to my knowledge you are SOL - mlppp is not an option - unless someone here knows something I don't - which is 100% likely :)

Now, that said you can configure your routing to split the traffic amongst different connections - so traffic to/from certain hosts use connection A, other hosts use B, etc.  You can even get fancy and route based on application and host if you wish.  Ci$co calls this Policy Based Routing.  I'm not sure if FBSD or another package such as pf allows similar functionality.  My guess would be yes - but I don't know anything about that.

As for "bonding" or aggregating your connections to appear as a single one - not an option AFAIK.

Thank you

Also, may be obvious to point out, but all (3) connections "must" be from the same provider.  In the lab you could MAYBE get a stable/usable connection from multiple providers (with just ppp or 'x' encap) by splitting the requests on the egress side - but it's highly unlikely in the real world.  In most cases the traffic load is asymmetrical and heavily biased towards ingress traffic, so even if you could get it to "work" - it wouldn't provide much benefit.

Just curious, what provider are you using?
