| Summary | 0007891: Wrong IP may update on MultiWAN | ||||||||||||
| Description | If a multiWAN system with a preference selected for a particular interface is assigned private IP's, Dynamic DNS ip referrer may use any route to fetch the address, and not end up using the preferred interface. A proposed fix would be to modify the following files: /usr/clearos/apps/clearcenter/libraries/Web_Service.php public function request($action, $postfields = "") to public function request($action, $postfields = "", $bind = NULL) add to "Set main curl options" section: if ($bind != NULL) curl_setopt($ch, CURLOPT_INTERFACE, $bind); /usr/clearos/apps/dynamic_dns/libraries/DNS_Update.php Line 229 $ip = $ip_referrer->get(); to $ip = $ip_referrer->get($ip); /usr/clearos/apps/dynamic_dns/libraries/IP_Referrer.php public function get() { $payload = $this->request('getip', NULL); return $payload; } to public function get($bind_ip) { $payload = $this->request('getip', NULL, $bind_ip); return $payload; } | ||||||||||||

Note: IP referrer lookups are not supported in Multi-WAN. Syswatch doesn't track IP referrers in MultiWAN, so it will never detect a changed IP. In syswatch: if ($numwans >= 2) { $config{is_multiwan} = $STATE_ENABLED; $config{use_get_ip} = $STATE_DISABLED; LogMsg("info", "config", "IP referrer disabled in multi-WAN\n"); } Keep in mind, Dynamic DNS updates still happen on boot and manually. If we want to add support for IP referrers in MultiWAN mode, this policy would need to change. I can't think of a good reason why this policy was put in place (?) ... but it's definitely intentional. |
