Routing problem dual WAN

Wed Jan 12, 2022 3:00 pm

hi,

Hope you guys can help my with the following problem.
I have a CCR2004 router connected to 2 providers.
1. fiber Primary over PPPOE CLIENT
2. coax Secondary DHCP CLIENT

The fiber provider gives out a block of /29 addresses.
The coax provider gives out one IP address in a /24 subnet. for example 213.2.2.50.

Now a have a client that is using our Unifi controller that is available via a port forward on the fiber connection
He is not able to connect to the controller if the second provider is enabled.
He is using the same coax provider and gets an IP in the same range for example 213.2.2.160

I think that the Mikrotik gets the initial connection via the primary line and wants to answer the request over the second line.
Other clients that are using the same coax provider with a different /24 subnet don’t have this problem.

Is there a way to foce the mirkotik to awnser via the primary line?

Look at this post. Start reading it from the last paragraph, which links it to your context.
