Conclusion: The Cisco RV215W Wireless-N VPN Router offers security-conscious small businesses a VPN server, wired and wireless networking, and firewall in one compact router. It falls short of being a great business-class router because of limited features and incremental improvements.
Pros: USB port for 3G/4G failover. Snappy interface. Improved firewall rules. IPv6 support. Easy to set up VPN.
Cons: No gigabit Ethernet. Only single-band (2.4 GHz) available. Only 5 concurrent VPN sessions supported.
