UDP over DNS
Posted: Thu Aug 03, 2017 9:45 am
Greetings!
I have some few tools implementing UDP over DNS using OpenVPN under UDP protocol!
The OpenVPN client seems to pass --proto udp --remote 127.0.0.1 1026 --route dns_server_ip 255.255.255.255 net_gateway
The local server in here seems to intercept this OpenVPN request and sends to openvpn server through some DNS queries.
Then under DNS queries there seems to be some TXT DNS record request and Reply and in here Request and Reply originate from a Certain Local port as the Source and are destined to DNS server through Port 53.
And Ultimately the Openvpn connection is Connected.
My concerned is how Can I implement this type of method,Can anyone who has seen this try to Give me an algorithm used to accomplish this.
REGARDS
