Lỗi vigor 2925 dynamic dns wan1 is not năm 2024

I have setup OpnSense with Multi_WAN fail over, which is working great. I have two WANs setup with the first as the default gateway and the second as a tier 2 fail over gateway. Disconnecting WAN1 (5.6.7.8) fails over to

Now I'm trying to get Dynamic DNS updates to work seamlessly when OpnSense fails over from WAN1 to

1, which is cached by OpnSense, so it isn't going to actually make the Dynamic DNS update request. Not the desired result, but it makes sense what's happening.

Next idea is that maybe I should have only one Dynamic DNS entry under

6 interface for the HTTP request. The code sets the

curl_setopt($ch, CURLOPT_INTERFACE, $this->_dnsRequestIfIP);

0 interface like this:

$this->_dnsRequestIf \= get_failover_interface($dnsRequestIf); if ($this->_dnsVerboseLog) { log_error("Dynamic DNS ({$this->_dnsHost}): running get_failover_interface for {$dnsRequestIf}. found {$this->_dnsRequestIf}"); } $this->_dnsRequestIfIP \= get_interface_ip($dnsRequestIf);

} $this->_dnsRequestIfIP = get_interface_ip($dnsRequestIf);

curl_setopt($ch, CURLOPT_INTERFACE, $this->_dnsRequestIfIP);

curl_setopt($ch, CURLOPT_INTERFACE, $this->_dnsRequestIfIP);

Is

$this->_dnsRequestIf = get_failover_interface($dnsRequestIf); if ($this->_dnsVerboseLog) {

 log_error("Dynamic DNS ({$this->_dnsHost}): running get_failover_interface for {$dnsRequestIf}. found {$this->_dnsRequestIf}");

} $this->_dnsRequestIfIP = get_interface_ip($dnsRequestIf);

6 not a valid interface for

curl_setopt($ch, CURLOPT_INTERFACE, $this->_dnsRequestIfIP);

0?

Playing around some more, I tried setting

curl_setopt($ch, CURLOPT_INTERFACE, $this->_dnsRequestIfIP);

5 for Dynamic DNS, which gives you two options for the interface,

curl_setopt($ch, CURLOPT_INTERFACE, $this->_dnsRequestIfIP);

6 and

curl_setopt($ch, CURLOPT_INTERFACE, $this->_dnsRequestIfIP);
