New server, running well 12.04 LTS on HP ML350.

Apache = great, inside our LAN. Apache = timeout, from WAN (NAT forwarded from firewall).

I have cleared all Iptables, read & checked every "allow" and "deny" in HTTP conf file & HTACCESS file.

With Iptables logging every packet, destination server sees the packet. Rebooted firewall, tested firewall (all good) and DEFINITELY port forwarding to new server.

Rebooted server, cleared out iptables, checked all 4 MACs, NIC cards are good and working. Static routing is 100% correct.

At a loss, all other 12.04 LTS servers are fine and configured just like this one.

Any help/pointers appreciated.

EDIT:

    Starting Nmap 5.21 ( http://nmap.org ) at 2013-06-04 22:53 BST
    Nmap scan report for site1.FQDN (82.X.X.X)

30333/tcp filtered unknown
Nmap done: 1 IP address (1 host up) scanned in 0.34 seconds

The request is: https:/warehouse1.FQDN:30333
This is getting firewall natted to "10.0.0.33:443".
I am starting to believe this is a hardware issue with the network cards on my LAN server, but any guidance appreciated.

Use nmap to do a port scan on the server itself nmap localhost then do a port scan from outside the LAN to see what ports are showing as open, if you like post the results. –  kingmilo Jun 3 '13 at 21:21
    
Sorry could not fit it all into a comment - have added "EDIT" above. –  GlassFeet Jun 4 '13 at 22:09
    
The Server is stuffed! Purchased second hand. There is a fix. If I "sudo shutdown -r now", then the problems above are present. If I abruptly hold the power, to force a shutdown, then reboot - everything works! As mentioned, it is kaput. –  GlassFeet Jun 5 '13 at 20:07
    
Just fyi, you nmap from external should have been done on all ports not by specifying a port as unfortunately the above external port scan provides us with very little information, just for future reference :) –  kingmilo Jun 5 '13 at 20:23
