Customized Block & Allow IP List for Auto Block.
Feature to manually add IP addresses to your Block and Allow lists to protect your network.

Feature will automatically block IPs that has made too many failed login attempts within a short period of time.
You will be informed by e-mail when this situation happens and see which IP address is trying to access your router being tried.
All blocked IP addresses will be stored on the “block list”.
But if your friend calls to say he forgot his password and was trying randomly to see if he can hit the jackpot. You can laugh and remove his IP address from the block list.
Friend's IP list for unlimited logons to: telnet, ssh and selected services will be good advantage.

[No more unauthorised access to your router, telnet, ssh and other services from blocked IP numbers or MAC Address numbers]
That should be a stardard for Draytek 2850Vn routers, don’t let hackers get the chance.
