I was wondering if someone could help me with the following as I am new to linux:
 
I have a firewall with 1 external  n/w card and 1 internal n/w card.
 
A number of machines on the LAN are on this firewall.  I have apache running on one of the machines inside the firewall.
I have one other person who dials in from home (outside the f/w using dynamic ip)
He wants to be able to connect to the instance of apache which running the internal machine.
 
I have tried using DNAT to route any traffic coming in from his range of ip address to the internal machine, port 80.
This doesn't seem to work. I have opened up port 80 on the firewall .
 
Eventually I will have to put in a rule that allows packets from any external address to be sent to this machine using port 80.
 
Could some help me with either of these problems
 
I'm using redhat 7.2
 
I'd be very greatful
