DNS Resolver has stopped working after 2.3.3
-
DNS resolution doesn't appear to be working for my iPhone, but only when I connect through my OpenVPN or IPSec tunnels.
Basic network layout is as follows:
192.168.1.0/24 LAN1
192.168.2.0/24 IPSEC
192.168.3.0/24 OPENVPN
192.168.5.0/24 LAN3Relevant IP Addresses
iPhone LAN1 IP - 192.168.1.67
iPhone IPSEC IP - 192.168.2.1
iPhone OPENVPN IP - 192.168.3.6
MachineA LAN1 IP - 192.168.1.16Problem
When I am connected to LAN1 via my WiFi, I can use the iPhone Prompt2 SSH client to connect to "MachineA" and have it properly resolve it's IP, 192.168.1.16.If I disconnect from my WiFi and connect to the Internet via my cellular connection on my iPhone, then connect to my home network via either OpenVPN or IPSEC, the Prompt2 client can't resolve "MachineA" but it can connect to it with just the IP, 192.168.1.16.
This seems to just have started after 2.3.3, but as far as I know, nothing in my configuration has changed.
Additional Facts
1. It seems to impact ONLY my OpenVPN connection and IPSec connection because I can resolve "MachineA" from LAN2.
2. Since I can connect with the IP via from my OpenVPN or IPSEC connections, it doesn't appear to be a firewall issue at least as far as connectivity and not DNS.![Screen Shot 2017-03-06 at 7.39.58 PM.png_thumb](/public/imported_attachments/1/Screen Shot 2017-03-06 at 7.39.58 PM.png_thumb)

Shortly after submitting this, I have checked the box "Provide a default domain name to clients" under Client Configuration in both my OpneVPN and IPSEC configuration settings and filled in my local domain and now everything appears to work.
Is this expected behavior?
