Hello,
I have a problem here and it's driving me mad. I have a persistent
tunnel with one session configured. And while the tunnel comes up again
after a connection loss the session remains in the WAITREPLY state. All
I can see is the following debug output:
Sep 9 08:23:02 OpenWrt daemon.debug openl2tpd[2017]: XPRT: tunl 44123:
zlb ack received: ns/nr=5/17
Sep 9 08:23:02 OpenWrt daemon.debug openl2tpd[2017]: XPRT: tunl 44123:
peer ns/nr is 5/17
Sep 9 08:23:02 OpenWrt daemon.debug openl2tpd[2017]: XPRT: tunl 44123:
pkt 16/5 is acked by nr 17
Sep 9 08:23:06 OpenWrt daemon.info openl2tpd[2017]: 9668/56219:

Sep 9 08:23:16 OpenWrt daemon.info openl2tpd[2017]: 9668/56219:
creating UNIX pppd context
Sep 9 08:23:27 OpenWrt daemon.info openl2tpd[2017]: 9668/56219:

Does anyone have an idea what I'm doing wrong here?
