Hey,
Been battling a weird network glitch all afternoon and I'm ready to pull my hair out over this.
Sometime through the night i lost connection to the outside world on most of my systems. Desktops, phones, servers just stopped working and responding. After some trial and error I realized that it was something related to my Ad-Guard servers. So, I logged into my OC200 and tried to change the DNS servers over to Google just to get around the issue for now. For some reason, the new DNS server settings will not take, and no device on my network will get the new server settings only the old ones. Only way for me to get around it is for me to manually set up a DNS server on any device on my network.
I'm not sure what is wrong or what I am doing wrong. I've tried changing the DNS server under the LAN/Port configuration as well as the DNSProxy settings but neither works. What could I be doing wrong?
Hardware:
OC200 v2 latest Firmware
SG2008P v 3.2
2x EAP653 V1 (Custom)
