is there anyway to check a config file or something that everything is set up correctly and then i will know the issue is with ip addressing or dns stuff |
If your new to iptables,use firestarter,here is the part on NAT;

havnt a clue where im going wrong now....
so this is what i have typed in .. as instructed [root@localhost server]# echo 1> /proc/sys/net/ipv4/ip_forward [root@localhost server]# iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to-source 192.168.0.1 -s 192.168.0.2 [root@localhost server]# iptables -A FORWARD -i eth0 -o eth1 -m state --state ESTABLISHED,RELATED -j ACCEPT [root@localhost server]# iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT [root@localhost server]# iptables -nL Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 Chain OUTPUT (policy ACCEPT) target prot opt source destination Chain RH-Firewall-1-INPUT (0 references) target prot opt source destination ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 255 ACCEPT esp -- 0.0.0.0/0 0.0.0.0/0 ACCEPT ah -- 0.0.0.0/0 0.0.0.0/0 ACCEPT udp -- 0.0.0.0/0 224.0.0.251 udp dpt:5353 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 udp dpt:631 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited [root@localhost server]# my set ups is as follows.... internet,, ------ eth0 ----- server ........................................... |____ eth1-------- HUB -------------(client_eth0) where eth0 is ip = 192.168.1.4 255.255.255.0 default gateway 192.168.1.1 DNS = 192.168.1.1 and eth1 is ip = 192.168.0.1 255.255.255.0 default gateway 192.168.1.4 and client_eth0 is 192.168.0.2 255.255.255.0 and its default gateway points to 192.168.0.1 DNS 192.168.0.1 i can ping the server from the client, the server can access the interenet and ping the client.. but the client cannot ping or get any internet access please help this is driving me insane |
iptables -I FORWARD -i eth0 -d 192.168.0.0/255.255.0.0 -j DROP
iptables -A FORWARD -i eth0 -s 192.168.0.0/255.255.0.0 -j ACCEPT iptables -A FORWARD -i eth1 -d 192.168.0.0/255.255.0.0 -j ACCEPT iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE Try adding this on the server,you may need to reverse the eth0 and eth1 as that is for WAN eth1 box eth0 intranet |
ok well i get this now...
but still doesnt allow the client to actually access the net [root@localhost tmp]# iptables -nL Chain INPUT (policy ACCEPT) target prot opt source destination RH-Firewall-1-INPUT all -- 0.0.0.0/0 0.0.0.0/0 Chain FORWARD (policy ACCEPT) target prot opt source destination DROP all -- 0.0.0.0/0 192.168.0.0/16 RH-Firewall-1-INPUT all -- 0.0.0.0/0 0.0.0.0/0 ACCEPT all -- 0.0.0.0/0 192.168.0.0/16 Chain OUTPUT (policy ACCEPT) target prot opt source destination Chain RH-Firewall-1-INPUT (2 references) target prot opt source destination ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 255 ACCEPT esp -- 0.0.0.0/0 0.0.0.0/0 ACCEPT ah -- 0.0.0.0/0 0.0.0.0/0 ACCEPT udp -- 0.0.0.0/0 224.0.0.251 udp dpt:5353 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 udp dpt:631 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited |
On the server did you link eth0 and eth1 for gentoo its
ln -s net.eth0 /etc/init.d/net.eth1 here is the guide I used,may help with iptables http://www.gentoo.org/doc/en/home-router-howto.xml |
