I will tell you exactly the same as Daniel wrote to me when I asked for it: what for? shell scripts+pfctl is good enough ;-) anyway, if you find anything worthing look at it, please let me know ;) -- I think that's the route we're going to take. I'm thinking about writing a listener on all of the servers in the pool that report to a "server" on the pf-enabled load balancers. The server would then add/remove devices from the tables using pfctl. We're interested in having this work in a heterogeneous OS environment so we'll probably use PERL instead of a Shell. If anyone wants a copy of the scripts just let me know and I'll send them individually or as an announcement to the list if there's enough interest. Regards, Mike
