blocking vpn to in future ?

I'm not familiar with that form of proxy. Have you tested the script to see if it alerts to use of VPN? Are you referring to Virtual Private Networks? Like you don't want servers connecting?

yes i m talking about virtual private networks actually the script dosent block VPN'S

Never really had any problems with VPN's to my knowledge, but sure I will look into adding it.

is same as tor or proxy allready blocked by your addon alot of people use them to hack or damage websites

Do you have an example one I could use to see what ports or masks they use to hide their IP?

some of them:

Internet Protocol Security (IPSec) uses IP protocol 50 for Encapsulated Security Protocol (ESP), IP protocol 51 for Authentication Header (AH), and UDP port 500 for IKE Phase 1 negotiation and Phase 2 negotiations. UDP ports 500 and 4500 are used, if NAT-T is used for IKE Phase 1 negotiation and Phase 2 negotiations

Secure Sockets Layer (SSL) uses TCP port 443 and works by using a private key to encrypt data that is transferred over the SSL connection. SSL also uses 465 Secure SMTP, 993 Secure IMAP, and 995 Secure POP.

Layer Two Tunneling Protocol (L2TP) uses TCP port 1701 and is an extension of the Point-to-Point Tunneling Protocol. L2TP is often used with IPSec to establish a Virtual Private Network (VPN).

Point-to-Point Tunneling Protocol (PPTP) uses TCP port 1723 and IP port 47 Generic Routing Encapsulation (GRE). PPTP provides a low-cost, private connection to a corporate network through the Internet. PPTP works well for people who work from home or travel and need to access their corporate networks. It is often used to access a Microsoft Remote Access Server (RAS).

but also 843,80 are used for vpn's

will these mod support with using together with cdn like cloudflare and such , is it possible to whitelist by usergroup and userid and ip ?

Alright I'll look into it, but from the sound of things it's mainly used by corporations and by blocking those people, you may lose valuable members that may be legitimately at work wanting to view your website.

Something I am working on for future versions.

The problem is not tor or vpn but how people use them and in this case alot of them use vpn's for atacking or hacking.Your addon is a life saver in general :-)
