Description

Setup:
  1. WAN PPPoE WAN
  2. HE.NET tunnel on WAN
  3. Static IPv6 on LAN
Steps to reproduce:
  • Create a UDP6 TAP OpenVPN client
  • Create and enable an iface for the client [for example, OVPN_AMS]
  • Reboot router
Expected:
  • OVPN_AMS is up
Actual:
  • OVPN_AMS is down. There is an error in the log: "TCP/UDP: Socket bind failed on local address [AF_INET6]2001:470:<censored>::: Can't assign requested address"

pfSense 2.3.0 does not have such bug as far as I can recall. It appeared in 2.3.1 but I was too lazy to report.

Confirmed, doesn't need PPPoE. An OpenVPN instance on an assigned GIF interface is enough. It's acting as though the GIF interface is not configured when OpenVPN attempts to start.

It happened in cases where specific IPv6 is selected to bind and interface is in 'tentative' state, as happened in the past with dpinger. I've pushed a fix, what depends of php-pfSense-module 0.33

Updated a VM that had two UPD6 OpenVPN servers on a HE.net GIF WAN and they were both running after the update. On older snaps they would not start automatically.
