Requirement

  1. For FTP-1 traffic, both Inbound & outbound traffic via ISP A
  2. For FTP-2 traffic, both inbound & outbound traffic via ISP B
  3. Achieve failover during ISP downtime.

I got no problem with configuring the outbound for both FTP-1 & FTP-2.
The complication comes-in on the inbound for FTP-2.
How can I influence the inbound of FTP-2 traffic coming back via ISP B.

I using an external DNS server delegating sub-domains to the Link Balancer, illustrated in this URL: Peplink | Pepwave - Forum

I know there’s a priority setting for DNS Server propagation. However this is a global setting, I can’t specified it for specific Domain Names in the Peplink.

Hi Anthony,

It is possible by setting connection priority for A record. Please go Network -> DNS Settings -> Click your Domain Name -> New A Record.

Please find the attached for the ftp1 and ftp2 settings.

By the way, WAN 1 and WAN 2 should have different public IP subnet.
