Sper ca am facut ce ai interbat (dupa cum vad gateway este 80.97.177.254 si ping-ul
este dezactivat pe gateway).
> incearca cu mtu mai mic (parca 576 era numarul magic).
Am incercat sa setez /proc/sys/net/ipv4/route/min_pmtu si
/proc/sys/net/ipv4/route/mtu_expires
la ceva mai mic, dar nu ajuta. Despre aceste setari vorbeai?
> sau pune /proc/sys/net/ipv4/tcp_syncookies pe 0
Nu ajuta. :-(
Numai sa clarificam: nu trebuie sa fac altceva decat se restartez conexiunea ppp, nu?
Evident, setarile am facut cand conexinuea era down.
