OpenVPN: can't connect to one specific device...

[BrinkGG]

I have a VPN tunnel set up so I can access my home network from anywhere else. Simple setup through PFsense.

I have 4 devices (Proxmox server, FreeNAS, Plex, Nextcloud) that I need to reach through the VPN. All of their IPs are static and saved by the DHCP server on PFsense. 

3 of them I can reach no problem through the tunnel, but I cannot ping, ssh, or access the WebUI for Proxmox. All of them are in the same IP range 192.168.0.0/24, and the tunnel connects to this same address range. 

Things I have tried:
Changing the IP (was originally 0.3, changed to 0.103 and 0.203 with no luck)

wireshark pcap said network traffic (No useable data as it's encrypted in the VPN)

recreating the VPN over a different port (no change) 

 

Any ideas what I'm doing wrong? I'm happy to take any assistance or ideas you may have.

Check the firewall configuration on the Proxmox, it probably drops traffic coming from your tunnel's IP address.

Will check that and update this post.

Cleared the Host firewall so it will accept any incoming connections from 192.168.*.* 

Still no change.

Try monitoring trafic on the Proxmox server by using tcpdump on its LAN interface, just to confirm that at least the traffic is reaching its interface.
