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
67 Restart timer for PPP protocol negotiation in seconds (default: 3).
70 Number of configure requests to send before giving up (default: 10).
73 Number of Configure-Nak requests to send before sending a
74 Configure-Reject (default: 5).
76 .BR primary_dns , " secondary_dns"
77 Whenever a PPP connection is established, DNS servers will be sent to the
78 user, both a primary and a secondary. If either is set to 0.0.0.0, then that
81 .BR primary_radius , " secondary_radius"
82 Sets the RADIUS servers used for both authentication and accounting.
83 If the primary server does not respond, then the secondary RADIUS
86 .BR primary_radius_port , " secondary_radius_port"
87 Sets the authentication ports for the primary and secondary RADIUS
88 servers. The accounting port is one more than the authentication
89 port. If no ports are given, authentication defaults to 1645, and
93 If set to true, then RADIUS accounting packets will be sent. A
95 record will be sent when the session is successfully authenticated,
98 record when the session is closed.
103 is on, defines the interval between sending of RADIUS interim
104 accounting records (in seconds).
107 Secret to be used in RADIUS packets.
110 A comma separated list of supported RADIUS authentication methods
111 ("pap" or "chap"), in order of preference (default "pap").
114 Port for DAE RADIUS (Packet of Death/Disconnect, Change of Authorization)
115 requests (default: 3799).
117 .B allow_duplicate_users
118 Allow multiple logins with the same username. If false (the default),
119 any prior session with the same username will be dropped when a new
120 session is established.
123 When the tun interface is created, it is assigned the address
124 specified here. If no address is given, 1.1.1.1 is used. Packets
125 containing user traffic should be routed via this address if given,
126 otherwise the primary address of the machine.
129 Address to send to clients as the default gateway.
132 Determines whether or not to send a gratuitous ARP for the
134 when the server is ready to handle traffic (default: true). This
135 setting is ignored if BGP is configured.
138 Sets the default speed (in kbits/s) which sessions will be limited to.
141 Number of token buckets to allocate for throttling. Each throttled
142 session requires two buckets (in and out).
145 If set to a directory, then every 5 minutes the current usage for
146 every connected use will be dumped to a file in this directory.
149 After starting up and binding the interface, change UID to this. This
150 doesn't work properly.
153 If set to true, then the current bandwidth utilization will be logged
154 every second. Even if this is disabled, you can see this information
160 Number of packets to read off each of the UDP and TUN fds when
161 returned as readable by select (default: 10). Avoids incurring the
162 unnecessary system call overhead of select on busy servers.
165 Sets the scheduling policy for the
169 This causes the kernel to immediately preempt any currently running
171 (normal) process in favour of
173 when it becomes runnable.
175 Ignored on uniprocessor systems.
178 Keep all pages mapped by the
183 Maximum number of host unreachable ICMP packets to send per second.
186 Maximum number of packets of downstream traffic to be handled each
187 tenth of a second per session. If zero, no limit is applied (default:
188 0). Intended as a DoS prevention mechanism and not a general
189 throttling control (packets are dropped, not queued).
192 Multicast cluster address (default: 239.192.13.13).
195 Interface for cluster packets (default: eth0).
197 .B cluster_hb_interval
198 Interval in tenths of a second between cluster heartbeat/pings.
200 .B cluster_hb_timeout
201 Cluster heartbeat timeout in tenths of a second. A new master will be
202 elected when this interval has been passed without seeing a heartbeat
205 .B cluster_master_min_adv
206 Determines the minumum number of up to date slaves required before the
207 master will drop routes (default: 1).
210 Enable negotiation of IPv6. This forms the the first 64 bits of the
211 client allocated address. The remaining 64 come from the allocated
212 IPv4 address and 4 bytes of 0s.
215 The routing configuration section is entered by the command
221 specifies the local AS number.
223 Subsequent lines prefixed with
224 .BI "neighbour " peer
225 define the attributes of BGP neighhbours. Valid commands are:
227 .BI "neighbour " peer " remote-as " as
229 .BI "neighbour " peer " timers " "keepalive hold"
233 specifies the BGP neighbour as either a hostname or IP address,
235 is the remote AS number and
238 are the timer values in seconds.
239 .SS NAMED ACCESS LISTS
240 Named access lists may be defined with either of
242 .BI "ip access\-list standard " name
244 .BI "ip access\-list extended " name
246 Subsequent lines starting with
250 define the body of the access\-list.
252 .B Standard Access Lists
254 Standard access lists are defined with:
256 .RB { permit | deny }
257 .IR source " [" dest ]
263 specify IP matches using one of:
276 are in dotted-quad notation, bits in the
278 indicate which address bits in
280 are relevant to the match (0 = exact match; 1 = don't care).
291 .BR 255.255.255.255 '.
294 .B Extended Access Lists
296 Extended access lists are defined with:
298 .RB { permit | deny }
300 .IR source " [" ports "] " dest " [" ports "] [" flags ]
313 are as described above for standard lists.
315 For TCP and UDP matches, source and destination may be optionally
320 .RB { eq | neq | gt | lt }
331 .RB { match\-any | match\-all }
332 .RB { + | - }{ fin | syn | rst | psh | ack | urg }
