This one. > Assuming that the Vigor in your case starts with > id=0x1, what happened to the other PAP AuthReq packets? Since I've at least two LACs behind my LNS, I guess that some LCPs are lost there - that's why seq. no is so high... > Maybe there is a communication problem between LAC and your server (or > possibly some more l2tp hops in between, if any)? I don't think so - because this problem arises if (and only if) Vigor is trying to authenticate with PAP, and this only happens with Vigor as a router. Well, to be fair, sometimes (very seldom - just checked the logs) seq. no is 8-9 (two cases), usually I got seq. 2, but with Vigor & PAP it is always > 0x70... May be those evil LACs are greedy to PAP packets? :) > There is a small chance the Vigor sees the ConfReq and disregards it, > because it has the same id (0x1) as one it has seen before, originating > from the LAC or any l2tp hop in between. Hmm... Could be... I am not sure what should be behaviour by RFC, but this could be a reason. Or bug in Vigor - they have a lot of them :) > One possibility would be to start LCP ConfReq id's in pppd at a different > value (I have not tried it; that would be in fsm.c, function fsm_init() ). Thanks for the tip - I'll try this :) > Before doing so you should plug a hub between the Vigor and the dsl modem > if possible. Not sure this is possible - I don't have DSL modem separately, but there is debug mode in Vigor itself - I can see some packet dumps... Will try :) Thanks! Regards, /Al
