Re: [NETVAERK] transparent fw og nat på samme maskine



Hej Rasmus
Skal jeg så sætte firewallens eksterne netkort til at have alle 5 IP
adresser og derefter benytte iptables til at forwarde trafikken til DMZ
kortet, samt at NATe trafik på den ene IP adresse til det internet kort?
Hvordan gøres det?

Det du skal kigge på / søge på er transparent firewalling eller bridging firewalling. Evt. prøv at droppe en mail i gruppen "sikkerhed". Har aldrig fået kigget på det, men det burde være ret nemt. Én ting du skal huske er at slå proxy arp til:
echo "1" > /proc/sys/net/ipv4/conf/all/proxy_arp
