But the renewal and error happens every 2 and a half mins
You can check lease time via i.e.# cat /var/db/dhclient.leases.igb1
lease { interface "igc0"; fixed-address 67.###.##.35; option subnet-mask 255.255.252.0; option routers 67.###.##.1; option domain-name-servers 75.75.75.75,75.75.76.76; option host-name "scuros-fw"; option domain-name "##.##.comcast.net."; option broadcast-address 255.255.255.255; option dhcp-lease-time 3600; option dhcp-message-type 5; option dhcp-server-identifier 96.###.###.143; option dhcp-renewal-time 657; option dhcp-rebinding-time 2700; renew 1 2022/8/1 19:55:10; rebind 1 2022/8/1 20:03:21; expire 1 2022/8/1 20:44:13;}
@Scuro do you have DHCP for your WAN and it's on interface igc0?
