[RESOLVED] WAN interface cycles UP and DOWN after DHCP PREINIT call

[the1corrupted]

Hello,

For some reason my WAN interface will cycle "UP" and "DOWN" after a dhclient PREINIT call on the interface

So far my only fix is to SSH into the firewall and run

ifconfig re1 up

This fixes it for the moment until it next occurs.


EDIT 2: If I run the command manually, I cannot replicate the problem.

Realtek brand interfaces are known to be problematic. Did you try to install the vendor driver?

Realtek brand interfaces are known to be problematic. Did you try to install the vendor driver?

I have not tried new drivers, is there something specific I need to load these drivers?

[Patrick M. Hausen]

System > Firmware > Plugins

Install os-realtek-re.

If that does not improve things I'd try to borrow better hardware for a test.

EDIT: OH WOW! The realtek driver cut down my reboot time by A LOT!

I have loaded the driver, I am noting this here as it only appeared during the install

I will give this some time to see what happens.

If you experience network hangs with IPv6 enabled,
you might need to disable the checksum offloading
by adding the following parameters to the related
ifconfig line in your /etc/rc.conf file:

-rxcsum -txcsum -rxcsum6 -txcsum6

[Patrick M. Hausen]

Checksum offloading is disabled in OPNsense by default. See here:

https://forum.opnsense.org/index.php?topic=43583.msg217965#msg217965

The messages shown when you install packages are not applicable in OPNsense as is clearly stated below that text box:

Output shown here for diagnostic purposes. There is no general need for manual system intervention.

After loading the realtek vendor drivers, the interface is still dropping the IP config but the pattern looks different

Somewhere in here is the smoking gun. I have removed connection-specific addresses for the moment

These are in reverse-time order as seen in the UI from most recent to oldest. At some point the link state changes DOWN during this process.

I use a WPA Supplicant to authenticate my connection, and I am still authenticated.

I have a temporary solution to auto reboot daily, and for the most part this is OK

The resolution on this was to load the realtek vendor driver. The new problem is not related to the previous instance, and is, in fact, the way the log off log on procedure with the WPA Supplicant is handled.
