I recently setup a server (SUSE 10) with apache,php,postgresql. The machine is on my internal network (192.168..). I created a port-forwarding rule in my D-LINK router; port 80 to access the web server and everything works great when accessing the http server from outside the network.
My question: What other security concerns should I be aware of? It seems to me all the other ports/programs would be blocked or inaccessible from the outside net? Any other concerns I should be aware of or blocks I should have in place?
