_______SERVER_______
..eth0......eth1.......eth2....eth3..
....|...........|.............|..............
....|...........|.............|..............
....|...........|.............|..............
...K1.........K2........internet........
na K2 NIE dziala internet i NIE dziala ping do servera
K1 i K2 sa dobrze skonfigurowane bo zamieniajac je miejscami internet dzialal na innych kompach ;]
W skr[u/o]cie siec dziala na eth0 ale juz nie chce dzialac na eth1
Co zrobic zeby dzialal net na eth1?
//Edit: Moze jest w tym blad ze pare kart ma ten sam adres czyli: 192.168.0.1??
Dolaczam kody:
→# ifconfig
→# cat /etc/init.d/maskarada
→# lspci | grep Et
→# cat /etc/network/interfaces
→# ifconfig
