Im not trying to discourage anything, but im not trying to lead someone down
the wrong path telling them that they can load balance two lines either.
First of all, we are both speculating about what they actually want to do...
You assumptions are that they are trying to do outbound load balancing
(connections originating from the inside of the router), which I never said
was not possible or bad, I just said that they were non-standard hacks,
which they are.
Second, I made the assumption that they are not trying to do outbound
balancing because very rarely do people have multiple 10Mb lines when they
are not doing hosting or something of that variety where the connections are
originating from the internet, not the local network. In this case, load
balancing on the router is not useful unless you use BGP. That was my whole
And as for throwing money around, I was trying to be useful and state that
there are free options available. And I would say that most providers which
will sell you a 10Mb link will provide BGP services, theres really no money
involved unless you buy cisco stuff... You just have to have justification
to get an AS number, and a trivial application fee.
