WAN Interface continuously cycles up and down
-
What do you suggest I do to further troubleshoot? I'd appreciate your help with this
-
If possible, first I'd try a different NIC to be sure it's not directly related to that one card/chip. It is not a general problem with that driver, so it's possible there is a hardware issue as well. It could also be related to the switch/cable/etc that it's plugged into.
-
Jimp, I've tested every cable on our network, including patch cables and the cabling in the walls…everything it wired as straight through no crossover which is good.
I'm running Verizon FIOS and have a straightthrough ethernet cable connecting the ONT box to the back of my pfsense box. Could it be that this cable should be a crossover and that's causing the problem? Any ideas anyone? If anyone is runnings FIOS with an ethernet connection directly from the ONT (Not COAX), plesae chime in. Thanks!

JIMP…What is the difference between setting the Speed and Duplex to "Default" rather than "autoselect" anyways?
-
In practice, very little. Default expresses no preference, leaving it up to the card/OS, which is almost every case will be autoselect.
Choosing autoselect will explicitly tell the card to do autoselect.

Jimp, I received a brand new NIC from Intel (same model I was running before) and it's also experiencing the same issue

Can you edit /etc/inc/interfaces.inc and make a change?
Change line 2639 from this:
if (!empty($wancfg['mtu']))to this:
if (!empty($wancfg['mtu']) && (get_interface_mtu($realhwif) != $wancfg['mtu']))If that works I can check that fix in as well.
-
I see the following:
if (!empty($wancfg['mtu']))
pfSense_interface_mtu($realhwif, $wancfg['mtu']);Am I changing this whole string to: if (!empty($wancfg['mtu']) && (get_interface_mtu($realhwif) != $wancfg['mtu']));
-
Just that first line, not the second line. No semicolon at the end since it's the opening of an if statement, just copy/paste my 'new' line over the existing single line.
-
Ok I replaced the line as mentioned and I'm still having the same problem. Once I change the setting from Default to autoselect, the WAN interface cycles up and down from obtaining an IP address, to dropping, to obtaining once again. Could it be a driver issue since this is a brand new NIC with the same problem?
-
that change would have only affected the MTU, not the link speed.
It could be a quirk with that specific chipset, yes. If it cycles the physical link when certain settings are applied, it can fall into a loop inside of the interface code because it does something like this:
Configuring the interface…
Set the link speed...
Interface speed causes link to go down/up
devd code sees the link go down/up and runs rc.newwanip
rc.newwanip configures the interface...
Which sets the link speed...
Which causes the link to go down/up
devd sees the link go down/up and runs rc.newwanipLather, rinse, repeat.

Sounds like this:
http://redmine.pfsense.org/issues/1572
It's been fixed in 2.0.1 (pending release) and 2.1.
https://github.com/bsdperimeter/pfsense/commit/0389f03498994dbdaf47543a325b58d14b1cdbabThanks for the heads up on this fix. I applied this fix manually and now I am able to spoof without it going into a loop. Thanks!!
