After switching to Fios, name resolution not working anymore.
Posted: Fri Oct 06, 2017 1:17 pm
I have an OpenVPN server up in Azure. I've been connecting fine for months from home (Windows laptop). The Azure network is using a 10.x address space, and my OpenVPN TAP adapter is given a 172.x address. Ever since the switch to Fios from Xfinity a few days ago Ip address are resolving incorrectly (going over the Fios gateway and not the assigned DNS).
Here's all the pertinent info i could think of f:
So you can see I have my 172 address for xyz.com (i changed the domain name to xyz.com just for the forum post)
Ping test:
Obviously “92.242.140.21” is wrong, it should be a 10.x address since all the servers I have at xyz.com are 10.x
IPv4 route print:
Nslookup showing default server:
i can get to my servers by IP, so the VPN connection is working, but anything by name isn't using the DNS on the TAP adapter (10.6.221.4,10.6.221.5)
again, this has worked fine for months, no changes client or server side except my switch to Fios..
Any ideas?
