Dear all,
Starting new thread to clear up the other one:
Re: Make a DHCP server using Fedora - Help
After going through the steps outlined and the guidance provided by great individuals that participate in this list :)
/* Done now added eth1 to DHCPARGS */
[olivares at localhost ~]$ cat /etc/sysconfig/dhcpd
DHCPDARGS=eth1
I need a little bit of help in setting up NAT. I can use the system-config-firewall or I can try using webmin or from command line, I feel I can achieve the goal.
How should I begin?
I had done this before, but because of other problems between the devices and my errors, it did not work :(
# Forward all packets from eth1 (internal network) to eth0 (the public internet)
iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT
# Forward packets that are part of existing and related connections from eth0 to eth1
iptables -A FORWARD -i eth0 -o eth1 -m state --state ESTABLISHED,RELATED -j ACCEPT
# Enable SNAT functionality on eth0. a.b.c.d are generally the ip of the eth0
iptables -A POSTROUTING -t nat -s 192.168.1.0/24 -o eth0 -j SNAT --to-source a
Thank you for helping,
Regards,
Antonio
