====== Port Forwarding To An Internal Web Server ====== This is an example of how you can port forward a port to an internal machine. In this case, we are port forwarding from the firewall to an Apache web server located on IP 192.168.0.10, with both HTTP and HTTPS services. ===== Basic Machine Setup ===== * eth0: Internet facing interface * eth1: LAN facing interface * Dynamic IPv4 address from ISP on eth0 * Internal LAN machines are on private subnet mask 192.168.0.0/24 * Web server is on 192.168.0.10 with ports 80 and 443 already open * A second web server is on 192.168.0.11, which needs to have its port 80 available on 8080 externally ===== Configuration ===== Config: etc/srfirewall/ipv4/portfw.conf # 80 tcp 192.168.0.10 80 eth0 443 tcp 192.168.0.10 443 eth0 8080 tcp 192.168.0.11 80 eth0
