Yes, you are right, these are just echo requests and replies: ppp phase changed[1]: phase=10 pppol2tp: input packet, len=0, tunnel=21944, session=8324, ns=0, nr=0 rcvd [LCP EchoReq id=0x1 magic=0x5e33e1ff] sent [LCP EchoRep id=0x1 magic=0xb4b7bbcf] pppol2tp: input packet, len=0, tunnel=21944, session=8324, ns=0, nr=0 rcvd [LCP EchoReq id=0x2 magic=0x5e33e1ff] sent [LCP EchoRep id=0x2 magic=0xb4b7bbcf] pppol2tp: input packet, len=0, tunnel=21944, session=8324, ns=0, nr=0 rcvd [LCP EchoReq id=0x3 magic=0x5e33e1ff] sent [LCP EchoRep id=0x3 magic=0xb4b7bbcf] pppol2tp: input packet, len=0, tunnel=21944, session=8324, ns=0, nr=0 rcvd [LCP EchoReq id=0x4 magic=0x5e33e1ff] sent [LCP EchoRep id=0x4 magic=0xb4b7bbcf] ..... pppol2tp: input packet, len=20, tunnel=21944, session=0, ns=2, nr=4 pppol2tp: input packet, len=20, tunnel=21944, session=0, ns=2, nr=4 ..... pppol2tp: input packet, len=0, tunnel=21944, session=8324, ns=0, nr=0 rcvd [LCP EchoReq id=0x1c magic=0x5e33e1ff] sent [LCP EchoRep id=0x1c magic=0xb4b7bbcf] pppol2tp: input packet, len=45, tunnel=21944, session=0, ns=3, nr=4 pppol2tp: input packet, len=0, tunnel=21944, session=8324, ns=0, nr=0 rcvd [LCP TermReq id=0x3 "User request"] LCP terminated by peer (User request)
May be the problem is in that timeout message: pppol2tp: input packet, len=0, tunnel=47089, session=35933, ns=0, nr=0 rcvd [LCP ConfReq id=0x2 <auth chap MS-v2> <magic 0xd9bb4bcc>] sent [LCP ConfAck id=0x2 <auth chap MS-v2> <magic 0xd9bb4bcc>] pppol2tp: timeout sent [LCP ConfReq id=0x5 <mru 1450> <magic 0xdadcdfcd>] pppol2tp: input packet, len=0, tunnel=47089, session=35933, ns=0, nr=0 rcvd [LCP ConfAck id=0x5 <mru 1450> <magic 0xdadcdfcd>] netif_set_mtu[1]: mtu=1450 ppp_send_config[1] ppp_recv_config[1] But if LwIP reached running phase, doesn't it mean l2tp initialisation was clear (even with that timeout)? May be this is wrong configure on VPN-server? But that is a quite simple, I connected to it successfully using Windows VPN-client.
