    Hello! I have a problem trying to connect zs to my PPPOE ISP. Then wan interface lights up and the tunnel process starts but i can not connect. I allso have a cupple of Clavister firewals and they connect hapily with my isp. I have called my isp to check if there are any mac address or other lockups in there system but no. The log looks like this:

    23:58:02 pppd 2.4.3 started by root, uid 0
    23:58:02 Using interface ppp0
    23:58:02 Connect: ppp0 <--> /dev/pts/0
    23:58:33 LCP: timeout sending Config-Requests
    23:58:33 Connection terminated.
    23:58:33 Using interface ppp0
    23:58:33 Connect: ppp0 <--> /dev/pts/1
    23:58:38 tcflush failed: Bad file descriptor
    23:58:38 Exit.
    23:58:43 pppd 2.4.3 started by root, uid 0
    23:58:43 Using interface ppp0
    23:58:43 Connect: ppp0 <--> /dev/pts/0
    23:59:14 LCP: timeout sending Config-Requests
    23:59:14 Connection terminated.
    23:59:14 Using interface ppp0
    23:59:14 Connect: ppp0 <--> /dev/pts/1
    23:59:19 tcflush failed: Bad file descriptor
    23:59:19 Exit.
    23:59:24 pppd 2.4.3 started by root, uid 0
    23:59:24 Using interface ppp0
    23:59:24 Connect: ppp0 <--> /dev/pts/0
    23:59:55 LCP: timeout sending Config-Requests
    23:59:55 Connection terminated.

    Any Hints on what could be wrong?


    Hi Again!

    It works… Very strange. after deleting the tunnel and recreating it workes…..

    NOW We have another problem. The Performance on the PPPOE interface SUCKS! I have an 8Mbit down and 1Mb up connection and I only get tops 0,5Mbit down performance… What could be wrong now?


    More information on the problem…. Latency for trafic goning through PPPOE had 1000ms… While bringing my clavister to be the pppoe client and route through it made the latency fall back to normal 5ms´

    Are there any logg’s other than thouse present in webinterface that i could check!?

    Please help this is very frustating….


    Hi All it seems that the performance issue was that my computer didn’t support ACPI so booting with noacpi option the performance boosted and latency droped



    Very interesting… My first thought with any PPPoE issues, especially with performance that dismal, is always to check the MTU size. I would not have thought ACPI would have caused this. You learn something new every day!
