Dhcp cant get Microsoft Classless Static Route (option 249)

ncat

Hello.
My ISP uses option 249 to send routes.
What i ve got (modified interfaces.inc)

Dec 27 23:20:41	dhclient[32765]: unknown dhcp option value 0xf9
Dec 27 23:20:41	dhclient[32765]: unknown dhcp option value 0xf9

unknown dhcp option value 0xf9: hex to dec means 249 which is "DHCP Option Code 249 (0xF9) - Microsoft Classless Static Route Option"
Is there any solution to "teach" pfsense work with them?
Thanks.

Here's how I deal with the incomplete implementation of DHCP Client.

Screen shots and old 2.0 patch here:
DHCP Client Additional Custom Options Patch

2.1 patch here:
Advanced DHCP Client Options & Config File Override
Protocol Timing
Send Options
Request Options
Require Options
Option Modifiers

Optional config override file example from 2.0.1.
