5b00273dfc move sessionfirewall into the tuntap. this needs testing. the name is also slightly wrong, since a crypto session can still be set up, packets are just accepted/rejected at the tun/tap level instead 2021-05-15 15:55:47 -05:00

Change DefaultIfName from "/dev/tun0" to "tun0" 
Specifying the full path to the interface in OpenBSD would result in:
panic: Interface name must be tun[0-9]*

Therefore, DefaultIfName should be changed to tun0 in order to make yggdrasil work out of the box.
