Firewall recommendation

Hello,

We are looking for a all-in-one firewall box with the following functions. Anyone have any recommendations:

- Good standard >100 mbit WAN firewall throughput
- SSL VPN portal style built in, support for mac and pc. a so called clientless solution, user logs in with AD account and should either be able to start a RDP session or a vpn tunnel
- support for pc and mac required for the above vpn function
- If possible the firewall should support two separate LANs on the inside, and support bandwithcontrol for each LAN (split the internet speed between two supported LANs behind the firewall with different ip subnets).

Any recommendations amongst the well known brands?

thanks,
joe
