Dual WAN with DNS issue

RouterOS General
1

Have a working Dual WAN. Odd issue is I have a (2) Ping prompt’s running; one to google.com and the other to 8.8.8.8

when I disconnect either of the WAN’s one of the Ping’s stops and the other continues fine. The Ping’s switch back and forth and the symptom remains constant depending on which WAN I disconnect.

I suspect that it is a DNS setting. WAN1 is DHCP from Mikrotik router and WAN2 is Static from Mikrotik router. All works but I know if I am loosing the name or ip resolution that it will effect something sooner or later?

Question I have is; if WAN1 pulls a static IP address it creates a dynamic DNS gateway route. I did enter in my own static for both WAN’s with no change. How do I get the resolution to remain constant on both IP and name?

I don’t think it is a DNS issue because your client is going to resolve the name when you first start the ping. The name is then cached locally until the TTL is reached for the DNS entry.

What happens if you stop the ping when it’s failing and start it again?

WAN1 is dhcp client
WAN2 is Static

WAN1 disconneted; both google & 8.8.8.8 continue to ping. Failover works via WAN2 Speedtest happy.

WAN2 disconnected; google.com pings and 8.8.8.8 does not. Failover works. Speedtest Happy.

good call on closing cmd and reopening to retest. Just have to figure out why I get the issue with WAN2 disconnected.
