Hi, guys I would please ask for their help with a problem that has frustrated me. Then I describe the scene I installed FC9 on my PC that will work as official proxy / firewall. The pc has 3 network cards eth4, eth5 and eth6 eth4-> 192.168.5.254 -> to a router eth5-> 192.168.1.231 -> toward LAN1 eth6-> 192.168.10.250 -> toward LAN2 - A cat / proc/sys/net/ipv4/ip_forward returns 1, - Also I have set in / etc / sysctl.conf net.ipv4.ip_forward = 1 - A ping from LAN2 to say 192.168.10.20 toward 192.168.10.250 work without problems - A ping from 192.168.10.20 works toward 192.168.5.254 - A ping 192.168.5.1 from FC9 toward running smoothly - A ping from FC9 to 192.168.1.250 running smoothly - Mii-tol eth4 eth5 eth6 returns eth4: negotiated 100BaseTX-FD flow-control, link ok eth5: negotiated 100BaseTX-FD flow-control, link ok eth6: negotiated 100BaseTX-FD flow-control, link ok - A ping from 192.168.10.250 toward 192.168.10.20 not work!!! - A ping from 192.168.10.20 to 192.168.5.1 via 192.168.10.250 as gw does not work. - A tracert from 192.168.10.20 to 192.168.5.1 return 192.168.5.1 to trace paths on a maximum of 30 hops 1 1ms 192.168.5.1: ICMP echo request 192.168.5.1> 192.168.5.254: ICMP echo reply 192.168.5.254> 192.168.5.1: ICMP echo request 192.168.5.1> 192.168.5.254: ICMP echo replay and therefore from fedora if I can do ping. - A cat /etc/selinux/config return SELinux=disabled and SELINUXTYPE =targeted. - A route-n Destination Gateway Genmask ... Ifacex 192.168.5.0 0.0.0.0 255.255.255.0 .... eth4 192.168.1.0 0.0.0.0 255.255.255.0 .... eth5 192.168.10.0 0.0.0.0 255.255.255.0 .... eth6 169.254.0.0 0.0.0.0 255.255.0.0 .... eth6 iptables has no rule, in fact I have executed the following iptables -t nat-F iptables -t mangle-F iptables -t filter-F iptales -P INPUT ACCEPT iptables -P OUTPUT ACCEPT iptables -P FORWARD ACCEPT What I can conclude that the forwarding is not working properly, or only partially. I have tried to add other options in sysctl.conf without success. I wish I could help me because I'm overwhelmed with this problem, you might miss something you add or remove within sysctl.conf or SELinux really much appreciate your help.
