TsgcWebSocketFirewall › Properties › Blacklist
Deny list of IP addresses and CIDR ranges whose connections are rejected before any other check.
property Blacklist: TsgcFirewallIPList read FBlacklist write SetBlacklist;—
Enable Blacklist.Enabled and populate the IPs string list with exact addresses (for example 192.168.1.100) or CIDR ranges (for example 10.0.0.0/8, 172.16.0.0/16). When a connection arrives from an IP that matches any entry in the list the firewall rejects it immediately and raises OnViolation with violation type fvBlacklist. Whitelist entries take precedence over the blacklist, so a whitelisted IP is never rejected by this check.
sgcWebSocketFirewall1.Blacklist.Enabled := True;
sgcWebSocketFirewall1.Blacklist.IPs.Add('10.0.0.0/8');
sgcWebSocketFirewall1.Blacklist.IPs.Add('192.168.1.100');
