RE: RADWare Linkproof? (or better ways to multihome)

have you considered getting 2 ranges (1 from each provider) and then getting
agreements from each where they cross advertise your allocated ranges out,


ISP 1 advertises its own /19 + /23 allocated to you from ISP2
ISP 2 advertises its own /19 + /23 allocated to you from ISP1

Some ISP's will not do this but I do know some of the big boys in the UK
will do it and the US is where we first saw this idea in us.

Then load each server across an address out of each range

This then gives you full redundancy of running BGP without the expense or
without requiring the in house expertise

I know exactly what you're talking about.  How much does the Linkproof
cost?  It could come down to a cost issue.  Looking at the Linkproof
documentation, it looks like you MAY still need a router.  It sounds like
the Linkproof is just a smart NAT box with some QOS features.  Are you
going to be advertising your IP block to both providers?  If one goes down,
will you still be routable globally?  If not, how could the Linkproof
possibly handle that?
