pfSense - Add Static Routes to pfSense DHCP Clients

• use OPTION 121 (OPTION 249 is deprecated)
• format = string
• convert subnet to hexadecimal (ex -> 255.255.255.0 -> /24 = 18)
• convert network to hexadecimal (ex -> 192.168.144.0 = c0:a8:90:00)
• convert gateway to hexadecimal (ex -> 192.168.144.253 = c0:a8:90:fd)
• concatenate string -> | Mask | Network | Gateway | = 18:c0:a8:90:c0:a8:90:fd

if you need multiple Routes added this way, simply concatenate all Routes
(as my personal experience goes, do not add the same option number more then once)

• Route 1 -> 18:c0:a8:90:c0:a8:90:fd
• Route 2 -> 18:aa:bb:cc:dd:ee:ff:00
• Result -> Route1:Route2:RouteN = 18:c0:a8:90:c0:a8:90:fd:18:aa:bb:cc:dd:ee:ff:00
