25 Settings are specified with
27 .BI "set " "variable value"
35 Set the level of debugging messages written to the log file. The
36 value should be between 0 and 5, with 0 being no debugging, and 5
40 This will be where all logging and debugging information is written
41 to. This may be either a filename, such as
44 .BR syslog : \fIfacility\fR ,
47 is any one of the syslog logging facilities, such as
51 If set, the process id will be written to the specified file. The
52 value must be an absolute path.
55 Path to random data source (default
57 Use "" to use the rand() library function.
62 for authenticating tunnel request. Must be the same as the LAC, or
63 authentication will fail. Only actually be used if the LAC requests
66 .BR primary_dns , " secondary_dns"
67 Whenever a PPP connection is established, DNS servers will be sent to the
68 user, both a primary and a secondary. If either is set to 0.0.0.0, then that
71 .BR primary_radius , " secondary_radius"
72 Sets the RADIUS servers used for both authentication and accounting.
73 If the primary server does not respond, then the secondary RADIUS
76 .BR primary_radius_port , " secondary_radius_port"
77 Sets the authentication ports for the primary and secondary RADIUS
78 servers. The accounting port is one more than the authentication
79 port. If no ports are given, authentication defaults to 1645, and
83 If set to true, then RADIUS accounting packets will be sent. A
85 record will be sent when the session is successfully authenticated,
88 record when the session is closed.
93 is on, defines the interval between sending of RADIUS interim
94 accounting records (in seconds).
97 Secret to be used in RADIUS packets.
100 A comma separated list of supported RADIUS authentication methods
101 ("pap" or "chap"), in order of preference (default "pap").
103 .B allow_duplicate_users
104 Allow multiple logins with the same username. If false (the default),
105 any prior session with the same username will be dropped when a new
106 session is established.
109 When the tun interface is created, it is assigned the address
110 specified here. If no address is given, 1.1.1.1 is used. Packets
111 containing user traffic should be routed via this address if given,
112 otherwise the primary address of the machine.
115 Address to send to clients as the default gateway.
118 Determines whether or not to send a gratuitous ARP for the
120 when the server is ready to handle traffic (default: true). This
121 setting is ignored if BGP is configured.
124 Sets the default speed (in kbits/s) which sessions will be limited to.
127 Number of token buckets to allocate for throttling. Each throttled
128 session requires two buckets (in and out).
131 If set to a directory, then every 5 minutes the current usage for
132 every connected use will be dumped to a file in this directory.
135 After starting up and binding the interface, change UID to this. This
136 doesn't work properly.
139 If set to true, then the current bandwidth utilization will be logged
140 every second. Even if this is disabled, you can see this information
146 Number of packets to read off each of the UDP and TUN fds when
147 returned as readable by select (default: 10). Avoids incurring the
148 unnecessary system call overhead of select on busy servers.
151 Sets the scheduling policy for the
155 This causes the kernel to immediately preempt any currently running
157 (normal) process in favour of
159 when it becomes runnable.
161 Ignored on uniprocessor systems.
164 Keep all pages mapped by the
169 Maximum number of host unreachable ICMP packets to send per second.
172 Maximum number of packets of downstream traffic to be handled each
173 tenth of a second per session. If zero, no limit is applied (default:
174 0). Intended as a DoS prevention mechanism and not a general
175 throttling control (packets are dropped, not queued).
178 Multicast cluster address (default: 239.192.13.13).
181 Interface for cluster packets (default: eth0).
183 .B cluster_hb_interval
184 Interval in tenths of a second between cluster heartbeat/pings.
186 .B cluster_hb_timeout
187 Cluster heartbeat timeout in tenths of a second. A new master will be
188 elected when this interval has been passed without seeing a heartbeat
191 .B cluster_master_min_adv
192 Determines the minumum number of up to date slaves required before the
193 master will drop routes (default: 1).
196 Enable negotiation of IPv6. This forms the the first 64 bits of the
197 client allocated address. The remaining 64 come from the allocated
198 IPv4 address and 4 bytes of 0s.
201 The routing configuration section is entered by the command

210 .BI "neighbour " peer
211 define the attributes of BGP neighhbours. Valid commands are:
213 .BI "neighbour " peer " remote-as " as
215 .BI "neighbour " peer " timers " "keepalive hold"
219 specifies the BGP neighbour as either a hostname or IP address,
221 is the remote AS number and
224 are the timer values in seconds.
225 .SS NAMED ACCESS LISTS
226 Named access lists may be defined with either of

282 Extended access lists are defined with:
284 .RB { permit | deny }

301 For TCP and UDP matches, source and destination may be optionally
