pfBlockerNG doesn't include L2TP interface in outbound floating rules
pfBlockerNG needs an option on the General tab for "L2TP Interface" similar to the "OpenVPN Interface" and "IPSec Interface" options.
Without the option the auto outbound floating rules do not have the L2TP VPN interface selected.

I'm not sure what you mean by "interfaces available". The problem is that there are no options for the L2TP interface similar to the two check box options below:
Select to add auto-rules for OpenVPN. This is only required when the OpenVPN Interface is not listed above.
OpenVPN Server (Outbound auto-rules only), OpenVPN Client (Both In/Outbound auto-rules)
These will be added to 'Floating Rules' or OpenVPN rules tab.
Select to add 'Outbound' auto-rules for IPSec. These will be added to 'Floating Rules' or IPSec rules tab.
