[solved] Shorewall help with Internet Sharing
I am new with linux so you might have to hold my hand through this.
Trying to set up internet sharing with the Linux machine (it has 2 nics in it, eth0 and eth1). I want the linux box to be the firewall (eth0 out to the net) and an XP machine connecting to the Linux machine's second nic (eth1) via crossover cable to have access to the internet.
eth0 IP shouldn't matter
eth1 IP = 192.168.2.254
XP Machine IP = 192.168.2.184
XP Gateway = 192.168.2.254
Now without the shorewall firewall installed I was able to run these commands and successfully share internet:
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward
apt-get install ipmasq
Those commands worked fine, but when I installed the shorewall firewall the internet sharing stopped working.
I have messed around with the rules/policies/zones with my only success being able to ping 192.168.2.254 from the XP machine.
Please help me or guide me to figuring this out. Thank you!
