So as I read this, you have a static IP from a provider, the link is down, and you want that static IP to work via another provider ? If that is the case, then as Tom has said, you CANNOT make it work<period>.* That IP is allocated to the ISP and will be routed as part of a larger block to that ISP. There is NOTHING* you can do to have that IP routed elsewhere. You may or may not be able to send packets out via the second provider with that IP as the source address, the second provider may or may not filter them out as forged - but you will never get any replies. * Actually that is not 100% - but to do anything else would require that your ISP do some tricks. The only trick likely to be supported, and only then by very, very few providers would be to provide you with two connections and run a routing protocol between you and the ISP to manage your traffic. Since this will normally involve having two links via the same technology, provider, and routing, there is likely to be little redundancy. I did also read about a provider that does it differently - you build two VPNs to them via whatever connections you have available, and they provide an IP from their range which is forwarded to you via the VPNs. I can't recall who it was, and it wasn't cheap, and I suspect it adds a certain amount of latency. ------------------------------------------------------------------------- SF.Net email is sponsored by: The Future of Linux Business White Paper from Novell.
