Maska 255.255.255.192 nefunguje?

[Super-User]

Asi jsem uplny magor, ale uz opravdu nevim co s tim - z nejakeho
(me neznameho) duvodu mi nechce Linux RH6.1cz s jadrem 2.2.14
pracovat na siti 212.47.17/26.

Zelezo by melo byt v poradku, jelikoz se jedna o stroj, ktery
jiz asi 14 dni bez problemu funguje na nasi vnitrni siti
192.168.1/24.

Opravdu jsem pouze zkousel prepichnout kabel z portu repeateru
vnitrni site do portu repeateru vnejsi site. A samozrejme
ten vnejsi repeater taky faxci, jelikoz tam hnizdi web server,
proxy a podobne veci.

Takze opravdu nevim jak dal. Jestli mi nikdo nerekne, ze
musim nekde neco zapnout, pak opradu budu nucen se zacit
prokousavat jadrem :(

Tady je vypis toho, co jsem zkousel (samozrejme ping!):

PS: Vzhledem k problemum s news serverem u GTS, jsem byl
nucen to posilat oklikou, takze objevi-li se tu nekdo,
kdo bude vedet co s tim, tak mi to muze forwardnout
na hop na unibase._krome_tohodle_.cz nebo proste sem,
jelikoz mam aspon read-only pristup (u sveho poskytovatele!!!)
