[SOLVED] Internet goes down every 5 or so minutes, recoverable only on reboot.
-
It would be helpful to me to see an extract of the pfsense log from a bit before the WAN link goes "down" to a couple of minutes afterwards.
Find attached the curtailed filter.log (renamed to filterDOTlog.txt)
FYI, upgraded to 20130622 build of pfSense 2.1-RC0. My network looks like this:
WAN (wan) -> bge0 -> v4: 192.168.1.50/24
LAN (lan) -> em0 -> v4: 192.168.27.1/24
DMZ (opt1) -> em1 -> v4: 10.10.27.1/24Appreciate for any inputs to overcome this problem. Thanks!

clog /var/log/system.logYou didn't miss anything, but that was my misunderstanding.
Find attached the system.log (systemDOTlog.txt, just of today else too large) for your perusal.

What I meant was both LAN and WAN interfaces remain 'green' (or say 'ifconfig bge0 up'), but internet connection drops. The WAN gets IP from the modem. The leased IP remains active, but internet fails every couple of minutes.

I saw this in your logs :
Jun 23 15:00:39 pfSense0 kernel: arp: 00:0e:08:cb:33:c0 is using my IP address 192.168.1.50 on bge0!
To mee, it's seems like same ip is use twice on the same network, leading to your problem.

Thanks for the pointer. The ARP table

UPDATE0: Maybe this could be the reason WAN connection frequently drops. Just a while ago I noticed in the dashboard that there is a crash report (several times within half an hour) reportedly due to a bug in pfSense. It first shows the first screenshot and then the details are found in the second screenshot as follows:Diagnostics: Crash reporter help
Unfortunately we have detected a programming bug.
Would you like to submit the programming debug logs to the pfSense developers for inspection?

Looks to be a Cisco/Linksys box from the first 3 mac numbers.

Indeed, Cicso-Linksys.
Do you have a router/wifi access point that's still trying to route?Edit: In fact looking at the MAC and using Google I would say there's a high likelihood it's one of these:

Yes, I have SPA3201 ATA, but not behind the pfsense box, ahead of it. The network is:
One of the ports of the ADSL router is connected to the pfSense box and another port to the Linksys SPA3210 which connects to a voip server located in another locatioon. And everything behind the pfSense has a different subnet addresses. So why does SPA 3201 try to register to pfSense box which has nothing to do with Linksys/Cisco/Sipura ATA?
After checking out the adsl router, I figured out that the IP I assigned to pfSense is within the DHCP range of the ADSL modem. I changed it and hopefully, it works! Thanks for the pointer.

That is probably not the issue. At some stage the modem will notice MAC address 00:0e:08:cb:33:c0 has IP address 192.168.1.50. Then data from the Internet that should go to to 192.168.1.50 goes to the SPA rather than the pfSense WAN interface and then systems downstream of pfSense appear to have lost contact with the Internet because they don't get responses to their requests.

Thanks to all for the pointer. pfSense community is awesome! :D
