    OK,

    I put the solution in place and had great results. The ONLY issue that
    I had, is with some routing. In order for the rest of the network to
    communicate with the hosts at the maintainence shed, I had to set a
    'static route'. I did so using DHCP, no problems there.

    However, I have a problem on the PPP server in its routing table:

    * I cannot add the static route to 'rc.conf':

    static_routes="theshed"
    route_theshed="192.168.1.234 192.168.1.233"

    because it creates the table entry pointing to the wrong interface -
    fxp0 instead of tun0

    * I tried the same thing in the 'ppp.conf' file. I tried several
    variations with no success:

    server:
       add 192.168.1.234 192.168.1.233
       add 192.168.1.234/30 192.168.1.233

    * I tried placing a shell script to be run in 'ppp.linkup' on the server
    server:
      bg /etc/ppp/setroute.sh

    and then setroute.sh:

    #!/bin/sh
    route delete 192.168.1.234
    route add 192.168.1.234 192.168.1.233

    STILL FAILS!

    But once the PPP link is established, if I add the route manually or
    run the shell script, it works fine thereafter. So the problem is that
    the routing table gets updated with the WRONG interface. The FreeBSD
    man page for 'route' is unclear about how to specify the interface on
    the command line. Any additional advice?
