I am in the process of adding a second firewall at one of my sites. The intent is to configure two firewalls in active/passive HA mode. The issue is that the ISP at this location is providing a "static" IP based on the MAC address registered in their systems. The MAC address presented to the ISP will change once the two firewalls are running in HA mode. In order to maintain our current IP so that we can maintain VPN tunnels between several offices, I need to ensure the MAC address is registered with the ISP. My question: Is it possible to define (hard code) the virtual MAC address used on the interface? This would allow me to pre-register the new MAC and ensure I don't lose my "static" IP address provide by the ISP. I understand it's possible calculate what it would be. If you can't define the MAC, how do you determine what it will be? Thanks, Dan Nadon
