I would really appreciate any help in understanding the below log entries of an unsuccessful PPTP VPN connection from an XP client to a m0n0wall PPTP server. The XP client used to test is on a lan behind a m0n0wall (same versions, 1.2). Looking at the log entries below, I see that "[pt0] LCP: SendConfigReq #" is sent 10 times before the connection attempt is terminated because "parameter negotiation failed". Is this SendConfigReq going from Server to Client? Does the repeating 10 times before failure indicate that something is getting blocked on its way back to the pptp client or a problem with the pptp server? On the client LAN, there is one and only one machine that can connect to this VPN. It is a single-nic W2k3/SBS machine connected to the m0n0wall which is set to fwd VPN requests to the w2k3/SBS machine. I've turned off the "Redirect VPN requests..." option but it doesn't change the outcome. I've compared these logs to a successful PPTP connection and notice that it only takes one "LCP: SendConfig" before a "rec'd configure request #0 link 0 (req-sent)" is received and the connection is negotiated successfully. Below are the complete log entries from the unsuccessful attempt of this PPTP client. Thanks very much - John These lines are in reverese chronological order with the newest at the top and the oldest at the bottom. ------------------------------------------- mpd: pptp0: killing connection with 71.39.xx.xx:57212 mpd: [pt0] LCP: Down event mpd: [pt0] link: DOWN event mpd: [pt0] device is now in state DOWN mpd: [pt0] device: DOWN event in state DOWN mpd: [pt0] LCP: phase shift ESTABLISH --> DEAD mpd: [pt0] LCP: state change Closed --> Initial mpd: [pt0] LCP: Down event mpd: [pt0] link: DOWN event mpd: [pt0] device is now in state DOWN mpd: [pt0] device: DOWN event in state CLOSING mpd: [pt0] LCP: state change Stopped --> Closed mpd: [pt0] LCP: Close event mpd: [pt0] link: CLOSE event mpd: [pt0] device is now in state CLOSING mpd: [pt0] device: CLOSE event in state CLOSING mpd: [pt0] closing link "pt0"... mpd: [pt0] bundle: CLOSE event in state OPENED mpd: [pt0] device is now in state CLOSING mpd: [pt0] IFACE: Close event mpd: pptp0: closing connection with 71.39.xx.xx:57212 mpd: [pt0] IFACE: Close event mpd: [pt0] IPCP: LayerFinish mpd: [pt0] IPCP: state change Starting --> Initial mpd: [pt0] IPCP: Close event mpd: [pt0] IFACE: Close event mpd: [pt0] PPTP call terminated mpd: pptp0-0: killing channel mpd: pptp0-0: clearing call mpd: [pt0] device: CLOSE event in state UP mpd: [pt0] LCP: LayerFinish mpd: [pt0] LCP: parameter negotiation failed mpd: [pt0] LCP: LayerFinish mpd: [pt0] LCP: state change Req-Sent --> Stopped mpd: ENDPOINTDISC [802.1] 00 09 5b 19 c8 a5 mpd: MP SHORTSEQ mpd: MP MRRU 1600 mpd: AUTHPROTO CHAP MSOFTv2 mpd: MAGICNUM 4b689978 mpd: MRU 1500 mpd: PROTOCOMP mpd: ACFCOMP mpd: [pt0] LCP: SendConfigReq #3 mpd: ENDPOINTDISC [802.1] 00 09 5b 19 c8 a5 mpd: MP SHORTSEQ mpd: MP MRRU 1600 mpd: AUTHPROTO CHAP MSOFTv2 mpd: MAGICNUM 4b689978 mpd: MRU 1500 mpd: PROTOCOMP mpd: ACFCOMP mpd: [pt0] LCP: SendConfigReq #2 mpd: ENDPOINTDISC [802.1] 00 09 5b 19 c8 a5 mpd: MP SHORTSEQ mpd: MP MRRU 1600 mpd: AUTHPROTO CHAP MSOFTv2 mpd: MAGICNUM 4b689978 mpd: MRU 1500 mpd: PROTOCOMP mpd: ACFCOMP mpd: [pt0] LCP: SendConfigReq #1 mpd: ENDPOINTDISC [802.1] 00 09 5b 19 c8 a5 mpd: MP SHORTSEQ mpd: MP MRRU 1600 mpd: AUTHPROTO CHAP MSOFTv2 mpd: MAGICNUM 4b689978 mpd: MRU 1500 mpd: PROTOCOMP mpd: ACFCOMP ------------------------ |
