pfSense

works now

I don't know why but $route_vpn_gateway is always empty here. I've added some debug info to the /usr/local/sbin/ovpn-linkup script:

/bin/echo "ifconfig_local=$ifconfig_local; route_vpn_gateway=$route_vpn_gateway; route_net_gateway=$route_net_gateway; dev_type=$dev_type;" > /tmp/${1}_router_dbg

Here is an output:

ifconfig_local=172.22.0.2; route_vpn_gateway=; route_net_gateway=; dev_type=tap;

Somehow OpenVPN doesn't initialize it's variables before calling "up" script. Also, I've attached ovpn log;

Here is a config file. Nothing fancy is there.

OpenVPN only has route_vpn_gateway in its environment variables if a route is pushed, even when you push route_vpn_gateway it's not in the env unless there is a route to use with it. That tripped me up at first when working on this. It really ought to be there any time it's pushed, but that'd be something to pursue upstream with OpenVPN.

this works now.
