VPN over DNS protocol
An option to allow VPN connexion over DNS protocol & ICMP protocol
Please add this! It would allow people to use VPN securely over networks that block or monitor traffic over stand ports, proxies or captive portals.
That would be interesting.
Something like this already exists for the DNS protocol: Iodine (http://code.kryo.se/iodine/), which uses the OpenVPN TAP to connect using UDP via the DNS ports.
It would be good to see for VyprVPN, as another option is always useful in places like China.
