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.
57 for authenticating tunnel request. Must be the same as the LAC, or
58 authentication will fail. Only actually be used if the LAC requests
61 .BR primary_dns , " secondary_dns"
62 Whenever a PPP connection is established, DNS servers will be sent to the
63 user, both a primary and a secondary. If either is set to 0.0.0.0, then that
66 .BR primary_radius , " secondary_radius"
67 Sets the RADIUS servers used for both authentication and accounting.
68 If the primary server does not respond, then the secondary RADIUS
71 .BR primary_radius_port , " secondary_radius_port"
72 Sets the authentication ports for the primary and secondary RADIUS
73 servers. The accounting port is one more than the authentication
74 port. If no ports are given, authentication defaults to 1645, and
78 If set to true, then RADIUS accounting packets will be sent. A
80 record will be sent when the session is successfully authenticated,
83 record when the session is closed.
86 Secret to be used in RADIUS packets.
89 When the tun interface is created, it is assigned the address
90 specified here. If no address is given, 1.1.1.1 is used. Packets
91 containing user traffic should be routed via this address if given,
92 otherwise the primary address of the machine.
95 Address to send to clients as the default gateway.
98 Determines whether or not to send a gratuitous ARP for the
100 when the server is ready to handle traffic (default: true). This
101 setting is ignored if BGP is configured.
104 Sets the default speed (in kbits/s) which sessions will be limited to.
107 Number of token buckets to allocate for throttling. Each throttled
108 session requires two buckets (in and out).
111 If set to a directory, then every 5 minutes the current usage for
112 every connected use will be dumped to a file in this directory.
115 After starting up and binding the interface, change UID to this. This
116 doesn't work properly.
119 If set to true, then the current bandwidth utilization will be logged
120 every second. Even if this is disabled, you can see this information
127 Interval between regular cleanups (in seconds).
130 Number of packets to read off each of the UDP and TUN fds when
131 returned as readable by select (default: 10). Avoids incurring the
132 unnecessary system call overhead of select on busy servers.
135 Sets the scheduling policy for the
139 This causes the kernel to immediately preempt any currently running
141 (normal) process in favour of
143 when it becomes runnable.
145 Ignored on uniprocessor systems.
148 Keep all pages mapped by the
153 Maximum number of host unreachable ICMP packets to send per second.
156 Maximum number of packets of downstream traffic to be handled each
157 tenth of a second per session. If zero, no limit is applied (default:
158 0). Intended as a DoS prevention mechanism and not a general
159 throttling control (packets are dropped, not queued).
162 Multicast cluster address (default: 239.192.13.13).
165 Interface for cluster packets (default: eth0).
167 .B cluster_hb_interval
168 Interval in tenths of a second between cluster heartbeat/pings.
170 .B cluster_hb_timeout
171 Cluster heartbeat timeout in tenths of a second. A new master will be
172 elected when this interval has been passed without seeing a heartbeat
176 The routing configuration section is entered by the command

185 .BI "neighbour " peer
186 define the attributes of BGP neighhbours. Valid commands are:
188 .BI "neighbour " peer " remote-as " as
190 .BI "neighbour " peer " timers " "keepalive hold"
194 specifies the BGP neighbour as either a hostname or IP address,
196 is the remote AS number and
199 are the timer values in seconds.
200 .SS NAMED ACCESS LISTS
201 Named access lists may be defined with either of
203 .BI "ip access\-list standard " name

211 define the body of the access\-list.
213 .B Standard Access Lists
215 Standard access lists are defined with:
217 .RB { permit | deny }
218 .IR source " [" dest ]
224 specify IP matches using one of:
237 are in dotted-quad notation, bits in the
239 indicate which address bits in
241 are relevant to the match (0 = exact match; 1 = don't care).
252 .BR 255.255.255.255 '.
255 .B Extended Access Lists
257 Extended access lists are defined with:
259 .RB { permit | deny }
261 .IR source " [" ports "] " dest " [" ports "] [" flags ]
274 are as described above for standard lists.
276 For TCP and UDP matches, source and destination may be optionally
281 .RB { eq | neq | gt | lt }
292 .RB { match\-any | match\-all }
293 .RB { + | - }{ fin | syn | rst | psh | ack | urg }
