I would also run
ipchains -F
to flush all the old rules first before you put anything else in.
other than that just make sure your route is correct and all your interfaces
are working.

P.S. You do not needs -b like Steve suggested. You may want to add
permissions for returning connections though: /sbin/ipchains -A input -j
ACCEPT ! -y -p tcp

Subject: [SLUG] Gateway/Firewall on Redhat 6.2
I'm having trouble setting up my Gateway/Firewall. It's been a long time
since I have done this. I entered the following into /etc/rc.d/rc.local
ipchains -P forward DENY
ipchains -A forward -j MASQ -s 192.168.0.0/24 -d 0.0.0.0/0
echo 1 > /proc/sys/net/ipv4/ip_forward
also in /etc/sysconfig/network
NETWORKING=yes
HOSTNAME="firegate.teviot.com.au"
GATEWAY="192.168.0.1"
GATEWAYDEV="eth0"
FORWARD_IPV4="yes"
The machine doesn't MASQ to or from the internet to intranet.
What am I doing wrong?
Regards
Adrian
