18.1 Legacy Series / WAN DHCP - Loss of IP no retry

« on: July 02, 2018, 04:44:11 pm »

Hello,

I recently set up a OPNSense system and everything worked great, but today the WAN interface lost its DHCP-IP.
The modem should give out a new IP as I have no static IP on the WAN interface. But for some reason this failed, I was able to solve the issue with reapplying the DHCP setting on the interface.

I also checked the log and will attach it below.
It seems as the WAN interface went down and came back up, but dhclient failed (error code 15) to gain a new IP.
I can understand that it could fail (nothing is perfect), but why does it not retry after some time instead of being stuck with no IP.

Is there a way to tell the dhclient to retry after one failure?

Thanks in advance
