VPN goes down when interface is not up. Can I set an interface to always up?
I have a site-site network setup with 2 pfsense on pcengine apu
The VPN connects local LAN (VPN-Client) to remote LAN (VPN-Server).
192.168.32.0/24 (local net) ---> 192.168.5.0/24 (remote net)
I also configured the firewall so that I can access from 192.168.32.0/24 the webgui/ssh 192.168.5.1 for admin purposes.
I have noticed that, when I unplug the cable from LAN interface on the remote box, I can not ping anything through the VPN at all anymore from the local side, not even the interface at 192.1685.1 itself. When I put the cable from LAN into a switch, pinging 192.168.5.1 works again even if the switch is sitting in a complete different subnet. As long as the cable is plugged in somewhere, even on a complete unconfigured port, I can ping the interface IP.
Normally that wouldn't be a problem since normally you have a Switch or something on the LAN-side but I actually planned to have on the VPN server only one machine which is a NAS without a switch in between. Now when the NAS should go down, I have a problem since I can not access the pfsense on 192.168.5.1 via VIA.
Is there a way to set the interface to always up no matter if there's a cable plugged in or not so that it keeps reviving packets through VPN?
You should be able to access the remote side GUI always via the VPN tunnel network IP.
Can the tunnel network IP work as like a gateway?
Because I have another problem, that I can't reach the site-site vpn from another vpn.
