Basically we was the first who developed “Access Code” based firewall. Its actually most simple and easy firewall ever. The reason of this firewall is:
1. Many unwanted people scan ips and try for login in vos client, so for access code now its double layers. Without allowing access code nobody can login vos client. So they need to know both details.
2. Our Firewall block all chinese/russian/hacker ip database. So its completely updated automatically from our ip databse.
3. We changed SSH ports as well and without allowing “Access Code” you can’t even login ssh.
4. Firewall rules updated every month, version wise rules are not dame, because each version have each type loophole, so need to study and work accordingly. Otherwise firewall will be useless.
