Low energy router supporting ssh, iptables and 2+ gigabit ports?

Hi all,

I am searching for a router which should have: - Low energy consumption (50W max) - Support a network with 5 normal computer users and one high traffic server (scrapping websites) - SSH support - iptables support - 1 input gigabit port - 2 output gigabit ports - 5GHz Wifi - Maximum cost of USD 250

No VPN/file transfers should be running on it so CPU speed is not that important.

What would you recommend me?

Thank you!
