OpenVPN on port 53
- by TossUser
I have an openvpn server setup on UDP port 53 on a public IP.
All the connecting clients gets pushed external DNS servers such as 8.8.8.8 and opendns.
Sometimes the resolution stops working on the connected vpn clients and I get strange packets in the openvpn log. Now my question is why is that?
When a VPN client, let's say 192.168.1.22 does a DNS query that query should go to 8.8.8.8:53 and then an UDP response packet should be sent back to 192.168.1.22 on a high UDP port.
Any ideas?
Thanks
