+.TP
+\fBConnectIPv4\fR (boolean)
+Set this to no if you do not want ngIRCd to connect to other IRC servers using
+the IPv4 protocol. This allows the usage of ngIRCd in IPv6-only setups.
+Default: yes.
+.TP
+\fBConnectIPv6\fR (boolean)
+Set this to no if you do not want ngIRCd to connect to other IRC servers using
+the IPv6 protocol.
+Default: yes.
+.TP
+\fBDNS\fR (boolean)
+If set to false, ngIRCd will not make any DNS lookups when clients connect.
+If you configure the daemon to connect to other servers, ngIRCd may still
+perform a DNS lookup if required.
+Default: yes.
+.TP
+\fBIdent\fR (boolean)
+If ngIRCd is compiled with IDENT support this can be used to disable IDENT
+lookups at run time.
+Default: yes.
+.TP
+\fBNoticeAuth\fR (boolean)
+Normally ngIRCd doesn't send any messages to a client until it is registered.
+Enable this option to let the daemon send "NOTICE AUTH" messages to clients
+while connecting. Default: no.
+.TP
+\fBOperCanUseMode\fR (boolean)
+Should IRC Operators be allowed to use the MODE command even if they are
+not(!) channel-operators? Default: no.
+.TP
+\fBOperServerMode\fR (boolean)
+If \fBOperCanUseMode\fR is enabled, this may lead the compatibility problems
+with Servers that run the ircd-irc2 Software. This Option "masks" mode
+requests by non-chanops as if they were coming from the server. Default: no;
+only enable it if you have ircd-irc2 servers in your IRC network.
+.TP
+\fBPAM\fR (boolean)
+If ngIRCd is compiled with PAM support this can be used to disable all calls
+to the PAM library at runtime; all users connecting without password are
+allowed to connect, all passwords given will fail.
+Default: yes.
+.TP
+\fBPredefChannelsOnly\fR (boolean)
+If enabled, no new channels can be created. Useful if you do not want to have
+other channels than those defined in [Channel] sections in the configuration
+file on this server.
+Default: no.
+.TP
+\fBRequireAuthPing\fR (boolean)
+Let ngIRCd send an "authentication PING" when a new client connects, and
+register this client only after receiving the corresponding "PONG" reply.
+Default: no.
+.TP
+\fBSSLCertFile\fR (string)
+SSL Certificate file of the private server key.
+.TP
+\fBSSLDHFile\fR (string)
+Name of the Diffie-Hellman Parameter file. Can be created with GnuTLS
+"certtool \-\-generate-dh-params" or "openssl dhparam". If this file is not
+present, it will be generated on startup when ngIRCd was compiled with GnuTLS
+support (this may take some time). If ngIRCd was compiled with OpenSSL, then
+(Ephemeral)-Diffie-Hellman Key Exchanges and several Cipher Suites will not be
+available.
+.TP
+\fBSSLKeyFile\fR (string)
+Filename of SSL Server Key to be used for SSL connections. This is required
+for SSL/TLS support.
+.TP
+\fBSSLKeyFilePassword\fR (string)
+OpenSSL only: Password to decrypt the private key file.
+.TP
+\fBSSLPorts\fR (list of numbers)
+Same as \fBPorts\fR , except that ngIRCd will expect incoming connections
+to be SSL/TLS encrypted. Common port numbers for SSL-encrypted IRC are 6669
+and 6697. Default: none.
+.TP
+\fBSyslogFacility\fR (string)
+Syslog "facility" to which ngIRCd should send log messages. Possible
+values are system dependent, but most probably "auth", "daemon", "user"
+and "local1" through "local7" are possible values; see syslog(3).
+Default is "local5" for historical reasons, you probably want to
+change this to "daemon", for example.
+.TP
+\fBWebircPassword\fR (string)
+Password required for using the WEBIRC command used by some Web-to-IRC
+gateways. If not set or empty, the WEBIRC command can't be used.
+Default: not set.
