Firewall Appliance Suggestions

["Blake T. Pfankuch" <blake () pfankuch me>]

Howdy,
                I am looking for something a little unique in a bit of a tough situation with some sticky requirements. 
 First off, my requirements are a little weird and I can't bend them a whole lot due to stipulations being put on me.  
I am in need a firewall appliance which can be run on VMware vSphere, with IPSEC support for multiple Phase 2 
negotiations within a single Phase 1.  I am also in need of something that can support VLAN interfaces on the LAN side, 
and ideally something with multi zoning so I can keep LAN side networks separate from each without ridiculous firewall 
rules.  Meaning build a zone for "Customer network 1" and it displays separately (ease of management and firewall 
config hopefully).  I need a minimum of 10 "zones" on LAN side (/29 or /30), and NAT support for LAN to WAN (to 
dedicate all outbound connections to a single IP from a specific zone), ideally something extremely scalable (100-200 
zones).  And here is the super fun part!  I need something that is going to be web managed primarily as minions will be 
doing most of the day to day maintenance, or very simple CLI config.  Willing to pay for something if need be, but 
looking for something that can easily handly 50-100mbit of throughput.

Any Ideas?

Thanks!
