My Firewall has 5 Interfaces:
  • 3 Interfaces for WAN (External IPs)
  • 1 Interface for LAN (10.0.0.10)
  • 1 Interface for DMZ (192.168.0.10)
The OpenVPN Server is listening on tcp Port 443 and udp Port 1194 (WAN Interface)

My proxmox Server hast two Interfaces:
  • 1 Interface for LAN (10.0.0.3)
  • 1 Interface for DMZ (192.168.0.3)

When I now try to access the GUI via VPN, I get the message "Request timeout", ping does not work either, however the VMs are accessible.
The GUI of the firewall is also accessible.


Any ideas?

Can you please post the following output from the proxmox

1. netstat -rn
2. cat /etc/network/interfaces


From the openvpn

1. Go to firewall>rules>openvpn

Check whether rules are existing ( share the screenshot)

The OpenVPN Server is located on the Firewall.

Traffic:

Client PC connects via OpenVPN client to the OpenVPN Server (Firewall), All Traffic which comes to specifc VPN port is forwarded to the OpenVPN Server. From there you can connect to the whole internal Network

I asked for rules in openvpn tab not wan, openvpn is connecting then no issues in wan side , just show what is there in firewall rules of openvpn tab

The OpenVPN Connection works. I have a rule for each Connection (UDP 1194 and TCP 443)

I Can access the Hardware Firewall through the OpenVPN and all VMs on Proxmox Host. The only thing that does not work is the access to the Proxmox Node.
(Ping, GUI,... not working)

Check whether Proxmox IP is published in the routing table advertised by OpenvPN
