Debugging local network connection to apex
I'm new to apex, almost zero networking skills
I'm using XP home edition (IP:192.168.1.5)
I've installed XE and upgraded apex to 3.1.2
All works fine locally
From other PC's on my home network I can't connect via browser with variations on "http://192.168.1.5:8080/apex"
At first I could only ping 192.168.1.5 but still not see it in my network workgroup
I'm using free Avast anti-virus and I also have the Windows firewall disabled
When I "paused" Avast I was able to "see" my apex pc in my network workgroup (better)
But I still can't get to apex.
I used a diagnostic tool (nmap) against 192.168.1.5 but did not find port 8080 open or any listeners on the apex machine other than the TNS listener.
I'm not sure what I should look for.
Is there a service I should look for? a configuration that I must set or change? I'm looking for a debugging strategy to prove all components on my host machine are in order, and then try to work from the lowest level forward from a remote machine (ping, nmap, etc.) until I can find the culprit.
Any nudge in the right direction would be appreciated.
Thanks
