Re: [TEKNIK] nat i fedora11



Tak, det er det jeg vil og har også prøvet det i forskellige varianter, men jeg har nu nok lavet en fejl ved at NAT'e til 192.168.1.2 i dedenstående figur.

Jeg prøver igen.

For så kører du:

# iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -j MASQUERADE
# iptables -A FORWARD -m state --state ESTABLISHED,RELATED -d
192.168.1.0/24 -j ACCEPT

på den omtalte maskine.

Du skal nok ændre første regel til
# iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

ellers bliver det, der går ud på eth0, også nat'et - og det du'r jo
ikke, når det er svar fra Internettet, der kommer tilbage til ANDEN MASKINE.
