The router have actived services below:
-USB Storage
-ProFTPD
-Samba
-VPN (PPTP)
-DDNS (xxxx.mynetgear.com)
From LAN PC(or phone), the shares on router's FTP and Samba can be visited successfully, via the router's IP address(192.168.1.2).
From WAN+VPN PC(or phone), the shares on router's FTP can be visitied successfully, via IP (192.168.1.2). Otherwise, shares of Samba can not be visited, neither \\DD-Wrt nor \\192.168.1.2.
After Win+R and input \\192.168.1.2, windows below jump out:
I noticed the mention "DO NOT USE THE ROUTER DATABASE", and I downloaded ver.r47581 and the latest ver.r47656.
Unfortunatly, both of them have problem, even worse..
Whith them, the FTP service don't work properly, and the VPN drops connection while FTP transfering.
So, I go back to the router database's latest version.r44715-2022.11.03. At least, FTP and VPN works fine on it, only the samba dosen't work.
Thank you all. I think waiting for new version would be wise.
