pptpd vpn trouble

Discussion in 'Linux Networking' started by Elliot English, Sep 22, 2003.

  1. Ok so here's my situation. I have a network which has a linux box as
    the router and firewall. On that box I want to run a vpn to which I
    can connect from anywhere on the net. I have setup poptop on the
    server and can connect to it succesfully from anywhere on the net,
    however, I can't access any of the computers on the network and they
    cannot access my comp elsewhere on the net. What do I have to do in
    order to make this link? pptpd appears to create a route when I
    connect but obviously it is not work. Reasons? Solutions? Anything
    would be helpful. PS. The firewall is not of concern at this moment so
    please disregard its existence. Thanks a lot in advance.

  3. I have gotten it so that pinging from either end shows up in
    /var/log/messages even though no response is recieved. Here are the
    entries from either end:

    Sep 22 21:26:47 server kernel: IN=eth1 OUT=ppp0 SRC=
    DST= LEN=60 TOS=0x00 PREC=0x00 TTL=127 ID=65209
    PROTO=ICMP TYPE=8 CODE=0 ID=512 SEQ=44800

    Sep 22 21:29:11 server kernel: IN=ppp0 OUT=eth1 SRC=
    DST= LEN=60 TOS=0x00 PREC=0x00 TTL=127 ID=10266 PROTO=ICMP
    TYPE=8 CODE=0 ID=1024 SEQ=2304

    Here is a copy of my routing table:

    Kernel IP routing table
    Destination Gateway Genmask Flags Metric Ref
    Use Iface * UH 0 0
    0 ppp0 * U 0 0
    0 eth1 * U 0 0
    0 eth0
    default UG 0 0
    0 eth0

    Hope this might shed some light as to what my problem is. Thanks.
