Dear Sir,

I am using the latest firmware 10.05.4 on my A2004NS that has L2TP VPN server function.

However, problem is found when starting the L2TP VPN server.  When the router starts, it needs to download some plugin for L2TP VPN server function to be used, but after a while the error "Failed to download plugin" shows up in both the L2TP VPN server page and the system log page.  

After numerous trials in different environment, the problem happens when connected to a particular ISP.  It seems there is DNS resolve or routing problem to the site that contains the plugin for download that the router needs every time it boots.  Grateful if you would investigate the problem.

I suggest to rewrite the firmware to include the L2TP VPN server code in the firmware file so there is not need to download the plugin after every reboot / power-up, or provide a window to manually upload the plugin file (like the firmware file).
