Why did vr0 link went down all of a sudden?
I haven't changed anything in vr0. I have been playing around with Firewall rule for WAN though. And all of a sudden my clients lost their ip. Here is what I have from Status:
LAN interface (vr0) Status no carrier MAC address 00:0d:b9:19:f8:50 IP address 192.168.1.1 Subnet mask 255.255.255.0 Media none In/out packets 41505/48873 (8.50 MB/23.31 MB) In/out errors 0/0 Collisions 3476
And here is what I have from the log:
Jul 29 21:06:24 last message repeated 7 times Jul 29 21:16:32 last message repeated 3 times Jul 29 21:22:10 last message repeated 2 times [b]Jul 29 21:29:53 kernel: vr0: link state changed to DOWN[/b] Jul 29 21:36:00 check_reload_status: reloading filter Jul 29 21:37:24 check_reload_status: reloading filter Jul 29 21:39:58 check_reload_status: reloading filter Jul 29 21:42:25 last message repeated 2 times Jul 29 21:54:07 dhcpd: Internet Systems Consortium DHCP Server V3.0.7 Jul 29 21:54:07 dhcpd: Copyright 2004-2008 Internet Systems Consortium.

This is not really cool. Can someone please shed light as to where I can check for this problem before I bulldozer over pfsense as an unstable DHCP router.
Thanks a lot
This turned out to be due to a loose cable on the router vr0 port end. I don't think it was any service down fault. However, would the logs anywhere indicate if a cable is un-plugged rather than service went down?
Link down means the NIC can't see the signal from the station at the other end of the cable - broken cable is the most likely cause but could include broken socket, broken NIC, loose connection etc.
