; ; Sample l2tpd configuration file ; ; This example file should give you some idea of how the options for l2tpd ; should work. The best place to look for a list of all options is in ; the source code itself, until I have the time to write better documetation :) ; Specifically, the file "file.c" contains a list of commands at the end. ; ; You most definitely don't have to spell out everything as it is done here ; ; [global] ; Global parameters: ; port = 1701 ; * Bind to port 1701 ; auth file = /etc/l2tp/l2tp-secrets ; * Where our challenge secrets are ; access control = yes ; * Refuse connections without IP match ; rand source = dev ; Source for entropy for random ; ; numbers, options are: ; ; dev - reads of /dev/urandom ; ; sys - uses rand() ; ; egd - reads from egd socket ; ; egd is not yet implemented ; ; [lns default] ; Our fallthrough LNS definition ; exclusive = no ; * Only permit one tunnel per host ; ip range = 192.168.0.1-192.168.0.20 ; * Allocate from this IP range ; no ip range = 192.168.0.3-192.168.0.9 ; * Except these hosts ; ip range = 192.168.0.5 ; * But this one is okay ; ip range = lac1-lac2 ; * And anything from lac1 to lac2's IP ; lac = 192.168.1.4 - 192.168.1.8 ; * These can connect as LAC's ; no lac = untrusted.marko.net ; * This guy can't connect ; hidden bit = no ; * Use hidden AVP's? ; local ip = 192.168.1.2 ; * Our local IP to use ; length bit = yes ; * Use length bit in payload? ; require chap = yes ; * Require CHAP auth. by peer ; refuse pap = yes ; * Refuse PAP authentication ; refuse chap = no ; * Refuse CHAP authentication ; refuse authentication = no ; * Refuse authentication altogether ; require authentication = yes ; * Require peer to authenticate ; unix authentication = no ; * Use /etc/passwd for auth. ; name = myhostname ; * Report this as our hostname ; ppp debug = no ; * Turn on PPP debugging ; pppoptfile = /etc/ppp/options.l2tpd.lns ; * ppp options file ; call rws = 10 ; * RWS for call (-1 is valid) ; tunnel rws = 4 ; * RWS for tunnel (must be > 0) ; flow bit = yes ; * Include sequence numbers ; challenge = yes ; * Challenge authenticate peer ; ; ; [lac marko] ; Example VPN LAC definition ; lns = lns.marko.net ; * Who is our LNS? ; lns = lns2.marko.net ; * A backup LNS (not yet used) ; redial = yes ; * Redial if disconnected? ; redial timeout = 15 ; * Wait n seconds between redials ; max redials = 5 ; * Give up after n consecutive failures ; hidden bit = yes ; * User hidden AVP's? ; local ip = 192.168.1.1 ; * Force peer to use this IP for us ; remote ip = 192.168.1.2 ; * Force peer to use this as their IP ; length bit = no ; * Use length bit in payload? ; require pap = no ; * Require PAP auth. by peer ; require chap = yes ; * Require CHAP auth. by peer ; refuse pap = yes ; * Refuse PAP authentication ; refuse chap = no ; * Refuse CHAP authentication ; refuse authentication = no ; * Refuse authentication altogether ; require authentication = yes ; * Require peer to authenticate ; name = marko ; * Report this as our hostname ; ppp debug = no ; * Turn on PPP debugging ; pppoptfile = /etc/ppp/options.l2tpd.marko ; * ppp options file for this lac ; call rws = 10 ; * RWS for call (-1 is valid) ; tunnel rws = 4 ; * RWS for tunnel (must be > 0) ; flow bit = yes ; * Include sequence numbers ; challenge = yes ; * Challenge authenticate peer ; ; [lac cisco] ; Another quick LAC ; lns = cisco.marko.net ; * Required, but can take from default ; require authentication = yes
