Additional options for PTPP and LT2P VPN

[Metathiax]

Is there any way to get the advanced options in the OVPN client available in the PTPP and L2TP clients for the merlin firmware?

Specifically I'm looking for the kill switch, ability to specify which devices are going though the tunnel, start on WAN, and to attempt to reconnect if it goes down.

Thanks.

EDIT: mis-entered L2TP everywhere, Can't fix the title or the tag.

If a PPTP/L2TP connection is defined and ACTIVE when the router is rebooted, then the PPTP/L2TP connection is automatically restarted @boot.
(NOTE: This may not be a desired effect, but you can use this technique and (crude) script

to delay the actual start.)

For a (dumb) kill switch, then you will probably need rules such as this for each device or subnet that must be blocked from using the WAN:

wan-start

iptables -I FORWARD -i br0 -s xxx.xxx.xxx.xxx -o $(nvram get wan0_ifname) -j DROP

If you want to use selective routing, then this script may help:
