Package: network-manager-l2tp Version: 1.20.12-1 Severity: normal X-Debbugs-Cc: hob...@poukram.net
Dear Maintainer, since upgrading to 1.20.12-1, I cannot connect to my ipsec/l2tp vpn anymore. I tried many things, but the only thing that works is disabling mppe, or downgrading to 1.20.10-1 Here are the debug log for 1.20.12-1: fév 20 20:04:02 sphax pppd[88301]: CHAP authentication succeeded fév 20 20:04:02 sphax pppd[88301]: nm-l2tp[87948] <info> [helper-88301] phasechange: status 8 / phase 'network' fév 20 20:04:02 sphax pppd[88301]: sent [CCP ConfReq id=0x1 <mppe +H -M +S +L -D -C>] fév 20 20:04:02 sphax pppd[88301]: rcvd [IPCP ConfReq id=0x1 <addr 192.168.50.1>] fév 20 20:04:02 sphax pppd[88301]: sent [IPCP TermAck id=0x1] fév 20 20:04:02 sphax pppd[88301]: rcvd [proto=0x8281] 01 01 00 04 fév 20 20:04:02 sphax pppd[88301]: Unsupported protocol 'MPLSCP' (0x8281) received fév 20 20:04:02 sphax pppd[88301]: sent [LCP ProtRej id=0x3 82 81 01 01 00 04] fév 20 20:04:02 sphax pppd[88301]: rcvd [LCP ProtRej id=0x2 80 fd 01 01 00 0a 12 06 01 00 00 60] fév 20 20:04:02 sphax pppd[88301]: Protocol-Reject for 'Compression Control Protocol' (0x80fd) received fév 20 20:04:02 sphax pppd[88301]: MPPE required but peer negotiation failed fév 20 20:04:02 sphax pppd[88301]: nm-l2tp[87948] <info> [helper-88301] phasechange: status 10 / phase 'terminate' fév 20 20:04:02 sphax pppd[88301]: nm-l2tp[87948] <info> [helper-88301] phasechange: status 5 / phase 'establish' fév 20 20:04:02 sphax pppd[88301]: PPPoL2TP options: debugmask 0 fév 20 20:04:02 sphax pppd[88301]: sent [LCP TermReq id=0x4 "MPPE required but peer negotiation failed"] fév 20 20:04:02 sphax pppd[88301]: rcvd [LCP TermAck id=0x4] fév 20 20:04:02 sphax pppd[88301]: nm-l2tp[87948] <info> [helper-88301] phasechange: status 11 / phase 'disconnect' fév 20 20:04:02 sphax pppd[88301]: Connection terminated.
