I am running Redhat 7.0 in the following configuration:

Two network cards:
eth0: connected to external DSL Cisco router
eth1: connected to internal machines 10.0.0.0/8

Now here is the situation:
I have masquerading working.  Some machines inside can access the outside
world (the behavior I want).

The problem is that there is an internal web server.  I have added the
following lines to my rc.firewall to get this behavior:

ipchains -A input -s $ANYWHERE -d $MY_EXT_IP 80 -p tcp -i eth1 -j ACCEPT
ipchains -A forward -i eth1 -s 10.10.10.15/32 -j MASQ
ipmasqadm portfw -f
ipmasqadm portfw -a tcp -L 99.291.291.299 80 -R 10.10.10.15 80

What happens is that without these lines, I get the response from:
telnet 99.291.291.299 80
connection refused

With these lines, no response at all.  From the gateway, it acts as it should,
so I know what it should do.

Please help,

-Greg
