Mam dwa komputery z Linuksem, oba widzą się poprzez interfejs eth2 (jeden pinguję drugiego na interfejsie eth2). Postanowiłem stworzyć połączenie pomiędzy tymi komputerami przez interfejs VLAN. No i niestety nie pingują się na tym interfejsie. Wszystko działa na VirtualBoxie. Poniżej konfiguracja. Doradźcie coś...
Komputer1: ifconfig eth2
