Do you have a VPN on your open source router?
One of the best features of the various flavors of open source firmware available for NETGEAR routers is the ability to enable use with your personal VPN client.
Enabling a VPN client on your router can have a variety of benefits. Most notably it will mask your IP (Internet Protocol) address and encrypt your connection in order to protect your security and privacy. All connections to your router, guest or private, run through your encrypted connection.
