IPsec VPN Endpoint

[asterger]

Consult from home office, accessing clients via Cisco's VPN client and IPsec. Current router is E3000 running factory firmware. I want to access clients via a hardware IPsec endpoint.

Would like IPsec VPN to be enabled on demand, support GigE WAN/LAN, USB/Samba and Wi-Fi g/n. Pricing should be under $500. Considering Cisco, ZyWall or third-party firmware for E3000.

Thanks in advance for your suggestions,
