After installing OpenVPN on the NAS4Free embedded and played around with routing and firewall, I have two requests / suggestions to the webGUI.
1)
The list of interfaces to choose from when creating a firewall rule, have only the "static" interfaces.
It would be nice if you could enter a dynamic interface as well e.g. "TUN0" which in my case is the dynamic vpn-tunnel interface.
The solution to my problem is to edit the config.xml and replace the hw interface name with the dynamic interface name.
But then you have to keep in mind NOT to change anything in this firewall rule through the webGUI, as it will automatically overwrite the interface name with "any" as the GUI does not know of the name "TUN0".
I know that the dynamic name will not be on the list as a drop down item because the interface does not exist at all time (dynamic). So a possibility to enter your own interface name as a text would be a help.
2)
Today the "lighttpd" (webGUI) is binded to the LAN interface IP address (automatically looked up by the initial script).
It would be nice to have the ability to choose which interface to listen on, if#1, if#2, All.
My issue was, that I didn't have remote access to the webGUI through the vpn-tunnel, as the only IP address I would know at the end of the tunnel, is the client tunnel ip address,- not the LAN ip address where the Lighttpd is binded.
The solution was a little script to modify the startup script to allow Lighttpd to listen on all interfaces (including the vpn-tunnel endpoint address), but a clean setting in the GUI would be prefered
Thanks for your great work making this NAS solution, all-in-a-box
Best regards
