Here is my setup:
UTM 9.004034
In the internal network, I have a server running Windows 7 professional. The IP address of server is 192.168.200.14. On this server, I run VirtualBox. The VirtualBox network adapter is bridged to the NIC on the server.
Within VirtualBox, I have created a VM. This VM can be accessed via SSH on the internal network. The IP address of the VM is 192.168.200.42.
When I am connected via L2TP VPN (10.242.3.2), I cannot access this VM via SSH. I cannot even ping this VM. I can access the server using RDP without issues. But any VM hosted on the server is inaccessible.
The VPN connection is established on my Android phone and I use an app ConnectBot for SSH. When the phone is connected to internal network over WiFi, I can access the VM just fine using this app. So it is clear that something in firewall is blocking SSH. I checked the logs and nothing.
So I created two DNAT rules:
Traffic selector: VPN Pool (L2TP) : ping : VM IP address
Destination translation: Server IP address: ping
Automatic Firewall Rule: Yes
Traffic selector: VPN Pool (L2TP) : SSH : VM IP address
Destination translation: Server IP address: SSH
Automatic Firewall Rule: Yes
With the first DNAT rule enabled, I can now ping the VM. I still cannot SSH into it. Is there any other DNAT rule/firewall rule required? I have been struggling for several hours but cannot make this work.
VPN --->internet--->UTM9->Server->VM on server
Thanks...
