I think the most recomended solution is to make a BGP peers with your two-ISP Put A single LEAF box running BGP and 3 NICs, one nic facing your server-farm , and 2 others facing your 2 ISP.
Or .. if you realy realy can't get peer, in this condition i'll prefer using dyndns tricks. In case you want to try dyndns tricks : 1. Give all your server IP address from both IP-block 2. Make a Ping script to ping check some host (on the internet) using diferent IP-address source for every ping-check 3. If one ping check failed, trigger your dynDNS client to register it self using diferent IP address. Note: I never do it yet. Hope fully DynDns client can register using user-defined ip address. Using this tricks hopefully your user always "see" single FQDN Regards -bino- ----- Original Message ----- From: "Michael Mansour" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Sunday, August 14, 2005 7:00 PM Subject: [leaf-user] 2 gateways > Hi, > > First let me commend this group on making LEAF, I've recently been looking > for a solution (and trying my own different solutions) to make available my > Webmail system when the primary broadband link goes down, on the secondary > broadband link I installed for this.
