I'm trying to get an IPSec VPN set up on my Debian home server, so that I can access my home network and browse without having my internet filtered by my college network, and so that I can perform maintenance on my home network from college as needed. I set up my server by following this link, and when I try to connect to it via Mac OS X 10.7.4, it will say The L2TP-VPN server did not respond. Try reconnecting. If the problem continues, verify your settings and contact your Administrator. It prints the following to the console:8/11/12 7:11:11.532 PM configd: SCNC: start, triggered by SystemUIServer, type L2TP, status 08/11/12 7:11:11.669 PM pppd: pppd 2.4.2 (Apple version 560.13) started by Jon, uid 5018/11/12 7:11:11.687 PM pppd: L2TP connecting to server '10.0.1.100' (10.0.1.100)...8/11/12 7:11:11.688 PM pppd: IPSec connection started8/11/12 7:11:11.708 PM racoon: Connecting.8/11/12 7:11:11.709 PM racoon: IPSec Phase1 started (Initiated by me).8/11/12 7:11:11.709 PM racoon: IKE Packet: transmit success.

I'm thinking that the server for some reason isn't getting or recognizing the vpn connection attempt, as it prints the same thing to the logs when I try connecting to a server that doesn't exist. The server has the IP 10.0.1.100, which is the IP that I am trying to connect to, just in case there is something wrong with the port forwarding on the router. Here is my three configuration files, configured in accordance to the how-to guide listed above. (I replaced the secrets with asterisks)/etc/freeradius/clients.conf# -*- text -*-#### clients.conf -- client configuration directives####  $Id$#########################################################################  Define RADIUS clients (usually a NAS, Access Point, etc.).##  Defines a RADIUS client.##  '127.0.0.1' is another name for 'localhost'.  It is enabled by default,#  to allow testing of the server after an initial installation.  If you#  are not going to be permitting RADIUS queries from localhost, we suggest#  that you delete, or comment out, this entry.####  Each client has a short name that is used to distinguish it from#  other clients.##  In version 1.x, the string after the word client was the IP#  address of the client.  In 2.0, the IP address is configured via#  the ipaddr or ipv6addr fields.  For compatibility, the 1.x#  format is still accepted.#client localhost {    #  Allowed values are:    #   dotted quad (1.2.3.4)    #       hostname    (radius.example.com)    ipaddr = 127.0.0.1    #  OR, you can use an IPv6 address, but not both    #  at the same time.#   ipv6addr = ::   # any.  ::1 == localhost    #    #  A note on DNS:  We STRONGLY recommend using IP addresses    #  rather than host names.  Using host names means that the    #  server will do DNS lookups when it starts, making it    #  dependent on DNS.  i.e. If anything goes wrong with DNS,    #  the server won't start!    #    #  The server also looks up the IP address from DNS once, and    #  only once, when it starts.  If the DNS record is later    #  updated, the server WILL NOT see that update.    #    #  One client definition can be applied to an entire network.    #  e.g. 127/8 should be defined with ipaddr = 127.0.0.0 and    #  netmask = 8    #    #  If not specified, the default netmask is 32 (i.e. /32)    #    #  We do NOT recommend using anything other than 32.  There    #  are usually other, better ways to achieve the same goal.    #  Using netmasks of other than 32 can cause security issues.    #    #  You can specify overlapping networks (127/8 and 127.0/16)    #  In that case, the smallest possible network will be used    #  as the best match for the client.    #    #  Clients can also be defined dynamically at run time, based    #  on any criteria.  e.g. SQL lookups, keying off of NAS-Identifier,    #  etc.    #  See raddb/sites-available/dynamic-clients for details.    ##   netmask = 32    #    #  The shared secret use to encrypt and sign packets between    #  the NAS and FreeRADIUS.  You MUST change this secret from the    #  default, otherwise it's not a secret any more!    #    #  The secret can be any string, up to 8k characters in length.    #    #  Control codes can be entered vi octal encoding,    #   e.g. \101\102 == AB    #  Quotation marks can be entered by escaping them,    #   e.g. foo\bar    #    #  A note on security:  The security of the RADIUS protocol    #  depends COMPLETELY on this secret!  We recommend using a    #  shared secret that is composed of:    #    #   upper case letters    #   lower case letters    #   numbers    #    #  And is at LEAST 8 characters long, preferably 16 characters in    #  length.  The secret MUST be random, and should not be words,    #  phrase, or anything else that is recognizable.    #    #  The default secret below is only for testing, and should    #  not be used in any real environment.    #    secret      = ********    #    #  Old-style clients do not send a Message-Authenticator    #  in an Access-Request.  RFC 5080 suggests that all clients    #  SHOULD include it in an Access-Request.  The configuration    #  item below allows the server to require it.  If a client    #  is required to include a Message-Authenticator and it does    #  not, then the packet will be silently discarded.    #    #  allowed values: yes, no    require_message_authenticator = no    #    #  The short name is used as an alias for the fully qualified    #  domain name, or the IP address.    #    #  It is accepted for compatibility with 1.x, but it is no    #  longer necessary in 2.0    ##   shortname   = localhost    #    # the following three fields are optional, but may be used by    # checkrad.pl for simultaneous use checks    #    #    # The nastype tells 'checkrad.pl' which NAS-specific method to    #  use to query the NAS for simultaneous use.    #    #  Permitted NAS types are:    #    #   cisco    #   computone    #   livingston    #   max40xx    #   multitech    #   netserver    #   pathras    #   patton    #   portslave    #   tc    #   usrhiper    #   other       # for all other types    #    nastype     = other # localhost isn't usually a NAS...    #    #  The following two configurations are for future use.    #  The 'naspasswd' file is currently used to store the NAS    #  login name and password, which is used by checkrad.pl    #  when querying the NAS for simultaneous use.    ##   login       = !root#   password    = someadminpas    #    #  As of 2.0, clients can also be tied to a virtual server.    #  This is done by setting the virtual_server configuration    #  item, as in the example below.    ##   virtual_server = home1    #    #  A pointer to the home_server_pool OR a home_server    #  section that contains the CoA configuration for this    #  client.
