am not too sure why it disconnects but you may want to try l2tpd as I fixed the packet echo problem (W2K complaining about loopback detected).

I'm using rp-l2tp with the road-warrior support (downloaded from CVS server this morning). I'm experiencing a disconnection problem from rp-l2tp : 1 or 2 minutes after connection has been established, it outputs an error and starts closing down the tunnel... 338.636 xmit_queued(32947/91): rws=8 cwnd=2 ssthresh=1 outstanding=0 338.636 dgram_send_to_wire() -> type=HELLO, tid=91, sid=0, Nr=5, Ns=6 338.636 loop in xmit_queued(32947/91): rws=8 cwnd=2 ssthresh=1 outstanding=1 339.646 xmit_queued(32947/91): rws=8 cwnd=1 ssthresh=1 outstanding=0 339.646 dgram_send_to_wire() -> type=HELLO, tid=91, sid=0, Nr=5, Ns=6 339.646 loop in xmit_queued(32947/91): rws=8 cwnd=1 ssthresh=1 outstanding=1 341.655 xmit_queued(32947/91): rws=8 cwnd=1 ssthresh=1 outstanding=0 341.655 dgram_send_to_wire() -> type=HELLO, tid=91, sid=0, Nr=5, Ns=6 341.656 loop in xmit_queued(32947/91): rws=8 cwnd=1 ssthresh=1 outstanding=1 345.665 xmit_queued(32947/91): rws=8 cwnd=1 ssthresh=1 outstanding=0 345.665 dgram_send_to_wire() -> type=HELLO, tid=91, sid=0, Nr=5, Ns=6 345.666 loop in xmit_queued(32947/91): rws=8 cwnd=1 ssthresh=1 outstanding=1 353.675 xmit_queued(32947/91): rws=8 cwnd=1 ssthresh=1 outstanding=0 353.675 dgram_send_to_wire() -> type=HELLO, tid=91, sid=0, Nr=5, Ns=6 353.675 loop in xmit_queued(32947/91): rws=8 cwnd=1 ssthresh=1 outstanding=1 Error: Too many retransmissions on tunnel (32947/91); closing down 361.685 tunnel_free(32947/91) 361.685 session((32947/91, 1319/1)) state established -> idle 361.685 session_free((32947/91, 1319/1)) Tunnel closing down 370.402 dgram_take_from_wire() -> type=HELLO, tid=32947, sid=0, Nr=6, Ns=5 Error: Invalid control message - unknown tunnel ID 32947 Error: Unknown tunnel 32947 Error: Unknown tunnel 32947 Error: Unknown tunnel 32947 Error: Unknown tunnel 32947 380.409 dgram_take_from_wire() -> type=HELLO, tid=32947, sid=0, Nr=6, Ns=5 Error: Invalid control message - unknown tunnel ID 32947 Error: Unknown tunnel 32947 390.413 dgram_take_from_wire() -> type=HELLO, tid=32947, sid=0, Nr=6, Ns=5 Error: Invalid control message - unknown tunnel ID 32947 400.416 dgram_take_from_wire() -> type=HELLO, tid=32947, sid=0, Nr=6, Ns=5 Error: Invalid control message - unknown tunnel ID 32947 Error: Unknown tunnel 32947 Error: Unknown tunnel 32947 410.419 dgram_take_from_wire() -> type=HELLO, tid=32947, sid=0, Nr=6, Ns=5 Error: Invalid control message - unknown tunnel ID 32947 Error: Unknown tunnel 32947 Error: Unknown tunnel 32947 Error: Unknown tunnel 32947 Error: Unknown tunnel 32947 Error: Unknown tunnel 32947 Error: Unknown tunnel 32947 420.424 dgram_take_from_wire() -> type=HELLO, tid=32947, sid=0, Nr=6, Ns=5 Error: Invalid control message - unknown tunnel ID 32947 My config is the following : VPN server is Linux Freeswan 1.99, rp-l2tp. VPN client is W2K, Service Pack 3. The VPN client is accessing the Internet through an ADSL router (using NAT) so nat_traversal has been enabled on server side. The VPN client is a road-warrior so I'm not supposed to know its IP in advance. /etc/l2tp/l2tp.conf : -------------------------- # Global section (by default, we start in global mode) global # Load handlers load-handler "/usr/lib/l2tp/plugins/sync-pppd.so" load-handler "/usr/lib/l2tp/plugins/cmd.so" # Bind address listen-port 1701 # Configure the sync-pppd handler.
