PfSense 2.4.2 - Config override

Guest

Since upgrading to the latest 2.4.2 snapshot from 2.4.0 RC I can no longer use a config override for dhcp on the WAN interface page

I see an error in the syslog showing

rc.bootup:Error:cannot open cf/conf/Orange_ipv4.conf in DHCP_Config_File_Override() for reading

I use the conf override to handle special parms for ORANGE FTTH so cant upgrade to 2.4.2 at the minute

Apologies if I'm suddenly making a school boy error but as I say its working at 2.4.0 RC version

I upgraded to take advantage of the bug fix in VLAN priority tags also needed for ORANGE FTTH :-) At least that bug has a work around with a Netgear switch

Well I did a fresh install and problem has gone

Note to anyone using VLANs which is what I’m using

At 2.4.0 and earlier a vlan of 832 for example defined on interface igb0
Resulted in an interface name of igb0_vlan832

Now it a 2.4.1 and later pfSense creates igb0.832

Caused me an additional bit of head scratching

Reading the changelog: https://doc.pfsense.org/index.php/2.4.1_New_Features_and_Changes helps in such cases.

Changed the VLAN interface names to use the 'dotted' format of FreeBSD, which is shorter and helps to keep the interface name smaller than the limit (16) This fixes the 4 digit VLAN issues when the NIC name is 6 bytes long.
