I have a Peplink Balance One Core running firmware version 7.0.0. I want to setup WAN1 to work with a local Fiber to the home 200/200 connection, and WAN2 is connected to a Comcast Business modem/router combo. WAN2 with the Comcast business connection works just fine, but setting up WAN1 gives me a “WAN failed DNS” test and the connection constantly disconnecting and reconnecting. I will note that I am using the ISP provided ONT/router combo in bridge mode with DHCP turned off, and manually configured the DNS to 126.96.36.199 and 188.8.131.52. This issue happens even with WAN2 not connected and WAN1 is the only ISP connected to the balance one core. Below are the settings I have used for WAN1:
Static IP: 192.168.1.2
Subnet mask: 255.255.255.0
Default Gateway: 192.168.1.1
DNS servers: 184.108.40.206 and 220.127.116.11
I have tried:
Health check set to “DNS lookup” using DNS servers listed above
Health check set to “PING” using DNS servers listed above
Health check disabled
Timeout: 5 seconds
Health Check Interval: 5 seconds
Health Retries: 3
Recovery Retries 3
When I use the above settings with health check enabled, I am able to load speedtest.net and usually run 1 speedtest before the “WAN failed DNS test” error occurs. Then it will disconnect, reconnect, and repeat. When Health check is disabled the disconnect and reconnect rate happens so quickly that I cannot even run a speedtest. I have tried locking the WAN1 port speed to 1000M full duplex, and setting the bandwidth to 1000M/1000M and 250M/250M all without any difference. Any advice on how to resolve this would be greatly appreciated.
Thanks in advance.
