There's really not that much difference. I have it setup right now with our passive device across town using a Metro Ethernet link. I have HA1 and HA2 on separate VLANs. You can setup HA2 as a L3 interface, but I haven't had a problem using it in L2 for nearly five years.
You just have to watch your timers and STP setup. The attached document should help there.
I am looking at the doc again and it says the control link if on separate broadcast domains you need to specify the gateway only . The two sites are on separate domains as each has a router . So the IP of the gateway is the public address of each unit . So on both the control and data link all we need to setup are the gateway ips and on the data link select IP for transport . Am I correct ?
