Apache on nondefault port, need help with iptables

  • 772

I am setting up apache to listen on port 8000.

it's working fine from 127.0.0.1 but the ip address on port 8000 does not work

the ip address is my router and i've already forwarded port 8000 to my box

nmap is not showing port 8000 and i assume i need an iptables rule to open this

so far i've ran: 

iptables -I INPUT -p tcp -m tcp --dport 8000 -j ACCEPT
iptables-save

but this seems to not be working so far.. any tips?

firewall apache-2.2 port-forwarding iptables

  1. you can verify that apache is actually listening on port 0.0.0.0:8000 by doing:

    netstat -ntlp

    you can verify iptables has the correct rule by doing:

    iptables -nvL

    In the iptables output make sure there are not any rules rejecting connections before the accept rule. Also, try verifying it's accessible from another computer on the same network before trying outside the network (through the router).

  2. I'm confused, what are you trying to do?

    If you want apache to listen to port 8000, just tell it to:

    <VirtualHost <your box IP>:8000>
    ServerName yourservername
    ...
</VirtualHost>

    As you mentioned, your router is already set to forward traffic to port 8000, so all should be fine.

    Make config changes as per above, restart apache. Telnet from the box to port 8000, see if that works, try then from another behind the router, and finally from the outside.
