Hello! I'd like to log syslog messages received via broadcast on UPD:514. In the logger PC there are multiple NICs, but I'm interested only to syslog messages received from these local interfaces: `10.200.255.254` and `127.0.0.1`. I've tried with the configuration posted below, but it doesn't always work (especially at system boot) because of the following error by the NXLog Windows Service. ``` ERROR failed to start im_udp; couldn't bind udp socket to 10.200.255.254:514; The requested address is not valid in its context. ``` This is my actual configuration ``` ... define LOGS_FILE ... ... Module xm_syslog Module xm_exec Module im_udp Host 10.200.255.254 Port 514 Exec parse_syslog(); Module im_udp Host 127.0.0.1 Port 514 Exec parse_syslog(); Module om_file CreateDir TRUE Sync TRUE File '%LOGS_FILE%' Path udp_lan, udp_host => file_syslog ``` The NIC has a static IP address, but I'm not sure it is already up when the nxlog service is executed at system boot by Windows. How can I perform this sort of filtering without using the firewall? I know I can listen to anything and `drop()` received messages with an `Exec` statement, but I don't know which variable to use (e.g. like `$MessageSourceAddress`) to specify the interface the message was received by. I was thinking to something like that: ``` Module im_udp Host 0.0.0.0 #
