Hi All,

I set up a firewall server in front of the apache server using port
forwarding technique that relies on iptables.

The apache and apache-ssl stop working after some time as shown below.

tcp        0      0 192.168.0.2:80          0.0.0.0:*
LISTEN     4821/apache
tcp        0      0 192.168.0.2:80          ???.??.??.??:4499
SYN_RECV   -

tcp        0      0 192.168.0.2:443         0.0.0.0:*
LISTEN     4834/apache-ssl
tcp        0      0 192.168.0.2:443         ???.??.??.??:4537
SYN_RECV   -

As shown above, apache and apache-ssl are running, but they don't
respond to requests. Thus, I receive "The operation timed out when
attempting to contact ???.??.??.??" from my firefox browser.
Please note that ???.??.??.?? is undisclosed ip address of the server.

Thanks in advance.
