OpenBSD 4.0 ADSL csatlakozási gond

OpenBSD-all

Hali!

A következő problémám volna, kérném a segítséget bárkitől, akinek van valamilyen ötlete. Otthonról ADSL-ről neteztem eddig, egy OpenBSD tűzfal osztotta szét a netet. Eddig userland pppoe-t használtam már 2 és fél éve, működött is gond nélkül. Nem sokkal azután, hogy 4.0-ra upgrade-eltem, 1-2 napig még működött, és onnantól kezdve sehogy nem akart OpenBSD alól csatlakozni. Nem értettem a dolgot, a tűzfalat ssh-val elértem, szabályok ugyanazok voltak, semmi változtatást nem csináltam a korábban használt konfig file-okban, csak az upgrade volt. Mivel nem volt ötletem, beraktam egy másik vincsit, visszaraktam a 3.9-et, de azzal se akart működni. Először arra gondoltam, a hálókártya lehet a gond, kicseréltem mindegyiket újakra, a helyzet maradt ugyanaz. Ugyanakkor az ADSL modem nem hiszem hogy rossz lenne, mivel WinXP alól ha próbáltam csatlakozni, gond nélkül ment a net, nem szakadt egyáltalán. Arra gondolok, hogy a Téonlány a kapcsolat másik oldalán valami műszaki paramétert megváltoztatott és OpenBSD userland pppoe azért nem tud csatlakozni. Elkezdtem logolni a próbálkozásokat, és a log file-ból is az látszott, hogy kb fél perc-egy perc után eldobja számomra érthetetlen okból a kapcsolatot, és nekiáll megint felépíteni. 1-2 perc múlva felépült, akkor egy jó fél percig ment a net, utána megint szakadt, és ez ciklikusan. Csak pinggel próbálkoztam DNS-re, az ment, és ott látszott hogy mikor szakadt. Ha megpróbáltam a tűzfalról lynx-el megnyitni bármilyen weblapot, jó ha félig bejött és már szakadt is.
Tegnap megpróbáltam a kernel pppoe drivert, és érdekes módon azzal működött OpenBSD alól, semmi szakadás nem volt. Viszont a kernel pppoe driverrel nem megy a nat az MTU eltérés miatt (1500-ethernet/1492-ADSL), belső hálóról sehogy nem sikerült elérni a netet. Hiába írtam át a pppoe(4) manual szerint mind a pf.conf-ot, mind ifconfig-al a hálózati kártyák MTU-ját, nem ment a NAT. Belső hálóról a kapott publikus IP-t még meg tudtam pingetni, kifelé semmi mást.

A userland-ből korábban használt ppp.conf:

default:
set log Phase Chat LCP IPCP CCP tun command
set redial 15 0
set reconnect 15 10000

pppoe:
set device "!/usr/sbin/pppoe -i rl0"
disable acfcomp protocomp
deny acfcomp
set mtu max 1492
set mru max 1492
set speed sync
enable lqr
set lqrperiod 5
set cd 5
set dial
set login
set timeout 0
set authname ********
set authkey ********
add! default HISADDR
enable dns
enable mssfixup

Ugyanezt meg lehet több helyen is találni a neten, és egész eddig ezzel működött gond nélkül. Ha valaki tud segíteni, elküldöm neki a ppp.log-ot is, ide nem akartam berakni mert nagy.
Kérdésem a következő lenne:
1. Van-e valakinek ötlete, mi történhetett hogy userland pppoe-vel nem megy a net, mit kellene módosítanom a ppp.conf-on?
2. Hogyan lehetne kernel pppoe-vel megoldani hogy menjen a NAT a belső hálóról és el lehessen érni a netet? MTU beállításra gondolok elsősorban.

Az általam használt ADSL modem egy Dialcom, hálózati kártyák Realtek8139D és SMC-1255TX.
Egész eddig Realtek-el ment a net, de hiába cseréltem SMC1255TX-re az ADSL modembe csatlakozó kártyát, az se segített. Nem a modem a rossz, és mindegy hogy 4.0-s vagy 3.9-es OpenBSD-vel próbálkoztam, az eredmény ugyanaz volt.

Minden segítséget előre is köszönök!

Majd innen ciklikusan ismétlődik. A furcsa azok a baromi nagy válaszidők, majd visszaáll a normális 15ms körüli értékre, majd megint szakad, és baromi nagy lagokkal tér vissza...
Remélem, van valami ötleted, nekem semmi a világon..
