Salut !
Am si eu o problema: a folosit cineva cu succes masquerading impreuna cu
PPPoE?
Ca in teorie merge, dar cu practica stam mai prost, adica:
setarile sunt ok, unele conexiuni merg (ping, telnet, unele pagini web,
etc) altele nu (pagini web mai mari de ex.).
Am cautat pe web si am gasit ca ar putea fi o problema de MTU, cum ca ar
fi un bug daca MTU ar fi diferit de 1500.
Problema mea este ca pe ppp nu pot schimba mtu (il ignora), si e default
pe 1492; iar daca incerc sa-l schimb pe eth0 ( e 1500, sa-l pun 1492)
tipa pppoe :-(
Conexiunea e ADSL, si in rest merge bec. Aceeasi configuratie dar cu
iesirea pe o placa ethernet merge bine.
Kernel-uri folosite : 2.2.17, 2.2.18, 2.4.1.
Pina una alta traiesc cu squid + socks :-(
Setarile sunt :
