I have ISPConfig 2.2 setup with two network cards. One NIC has an internal IP address, while the other one has a WAN IP. Sometimes the WAN IP crashes and stops responding to web requests in both port 80 and 81 (ISPConfig). I can still reach the server if I use the internal IP address on both ports 80 and 81. Has anyone else experience this issue before? I had a feeling that maybe someone is DDosing my server but I'm not too sure if that's the case or that particular part just keeps crashing. I have to reboot the server in order to get it back to listen on the WAN IP and have the website load. I only have one site setup on the ISPConfig server. When I try to load the site from the outside DNS name, it tries to connect to the site, it looks like it gives a response but then just times out.
Falko, Sorry to reply so late but I switched out the network card on the server with an Intel one. It started to work with no problems for a year but now, I'm having the same issue again. I can access the website from the Internal network fine. All the pages load but when I try to browse the website from the external WAN IP (direct connection from cable modem to the network card, it doesn't load. I tried to disable fail2ban on the server to see if it was blocking connections but that didn't help. I looked under /etc/apache2/vhosts/Vhosts_ispconfig.conf file. There was 3 entries that looked a little strange. It read like this: ################################### # # ISPConfig vHost Configuration File # Version 1.0 # ################################### # NameVirtualHost 10.4.1.x:80 (my internal ip address) <VirtualHost 10.4.1.x:80> ServerName localhost ServerAdmin root@localhost DocumentRoot /var/www/sharedip <IfModule mod_rewrite.c> RewriteEngine on RewriteCond %{REQUEST_METHOD} ^(TRACE|TRACK) RewriteRule .* - [F] </IfModule> </VirtualHost> NameVirtualHost 1.2.3.4:80 (EXTERNAL IP ADDRESS FROM ISP) <VirtualHost 1.2.3.4:80> ServerName localhost ServerAdmin root@localhost DocumentRoot /var/www/sharedip <IfModule mod_rewrite.c> RewriteEngine on RewriteEngine on RewriteCond %{REQUEST_METHOD} ^(TRACE|TRACK) RewriteRule .* - [F] </IfModule> </VirtualHost> NameVirtualHost 1.2.3.4:80 (same IP as last entry, double entries!) <VirtualHost 1.2.3.4:80> ServerName localhost ServerAdmin root@localhost DocumentRoot /var/www/sharedip <IfModule mod_rewrite.c> RewriteEngine on RewriteCond %{REQUEST_METHOD} ^(TRACE|TRACK) RewriteRule .* - [F] </IfModule> </VirtualHost> # # ###################################### # Vhost: www.mywebsite.com:80 ###################################### # # <VirtualHost 1.2.3.4:80> (same as above WAN IP) SSLCertificateChainFile /var/www/web1/ssl/gd_bundle.crt ServerName www.mywebsite.com:80 ServerAdmin [email protected] DocumentRoot /var/www/web1/web ServerAlias mywebsite.com DirectoryIndex index.html index.htm index.php index.php5 index.php4 index.php3 in$ Alias /cgi-bin/ /var/www/web1/cgi-bin/ AddHandler cgi-script .cgi AddHandler cgi-script .pl ErrorLog /var/www/web1/log/error.log AddType application/x-httpd-php .php .php3 .php4 .php5 php_admin_flag safe_mode Off AddType text/html .shtml AddOutputFilter INCLUDES .shtml Alias /error/ "/var/www/web1/web/error/" ErrorDocument 400 /error/invalidSyntax.html ErrorDocument 401 /error/authorizationRequired.html ErrorDocument 403 /error/forbidden.html ErrorDocument 404 /error/fileNotFound.html ErrorDocument 405 /error/methodNotAllowed.html ErrorDocument 500 /error/internalServerError.html ErrorDocument 503 /error/overloaded.html AliasMatch ^/~([^/]+)(/(.*))? /var/www/web1/user/$1/web/$3 AliasMatch ^/users/([^/]+)(/(.*))? /var/www/web1/user/$1/web/$3 <IfModule mod_rewrite.c> RewriteEngine on RewriteCond %{REQUEST_METHOD} ^(TRACE|TRACK) RewriteRule .* - [F] </IfModule> </VirtualHost> # <IfModule mod_ssl.c> <VirtualHost 1.2.3.4:443> (same ip as above) SSLCertificateChainFile /var/www/web1/ssl/gd_bundle.crt ServerName www.mywebiste.com:443 ServerAdmin [email protected] DocumentRoot /var/www/web1/web ServerAlias mywebsite.com DirectoryIndex index.html index.htm index.php index.php5 index.php4 index.php3 in$ Alias /cgi-bin/ /var/www/web1/cgi-bin/ AddHandler cgi-script .cgi AddHandler cgi-script .pl ErrorLog /var/www/web1/log/error.log AddType application/x-httpd-php .php .php3 .php4 .php5 php_admin_flag safe_mode Off AddType text/html .shtml AddOutputFilter INCLUDES .shtml SSLEngine on SSLCertificateFile /var/www/web1/ssl/www.mywebsite.com.crt SSLCertificateKeyFile /var/www/web1/ssl/www.mywebsite.com.key Alias /error/ "/var/www/web1/web/error/" ErrorDocument 400 /error/invalidSyntax.html ErrorDocument 401 /error/authorizationRequired.html ErrorDocument 403 /error/forbidden.html ErrorDocument 404 /error/fileNotFound.html ErrorDocument 405 /error/methodNotAllowed.html ErrorDocument 500 /error/internalServerError.html ErrorDocument 503 /error/overloaded.html AliasMatch ^/~([^/]+)(/(.*))? /var/www/web1/user/$1/web/$3 AliasMatch ^/users/([^/]+)(/(.*))? /var/www/web1/user/$1/web/$3 SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown downgrade-1.0 for$ <IfModule mod_rewrite.c> RewriteEngine on RewriteCond %{REQUEST_METHOD} ^(TRACE|TRACK) RewriteRule .* - [F] </IfModule> </VirtualHost> </IfModule> # # When I run the restart apache command, I get this error: goldmine:/etc/apache2/sites-available# /etc/init.d/apache2 restart Restarting web server: apache2[Mon May 20 16:55:16 2013] [warn] NameVirtualHost 1.2.3.4:80 has no VirtualHosts ... waiting [Mon May 20 16:55:17 2013] [warn] NameVirtualHost 1.2.3.4:80 has no VirtualHosts I edited the /etc/apache2/vhosts/Vhosts_ispconfig.conf file and took out the duplicate external IP addresses and the error went away but the external IP website still doesn't work.

The first one is the built-in Dell one with dual nics (the one with 10.4.1.x), another is an Intel card with one port, which is the set with the external WAN IP. This card originally connected to the cable modem. Last, is the newest Intel dual nic card, which I replaced the faulty Intel one above, which has the external wan IP configured it. This port is connected to the cable modem, other was not setup with an IP or connected with any wiring. I SSH'd into the box with the internal IP address and pinged the external IP and it responds with a ping but it doesn't work when I'm from the outside. This is a really weird problem and I can't seem to figure it out. I already tried reloading the machine (rebooting), disabling the eth0 interface (ifconfig eth0 down), modifying the /etc/apache2/vhosts/vhosts_ispconfig.conf file. Restarting /etc/init.d/apache2. I'm running ISPConfig v2.2 on a debian 5.0.1 (lenny) with one default site. There are no other websites being hosted other than my main site. I tried also looking at /etc/apache2/httpd.conf but the file is totally empty (no text in there). I don't know if ISPConfig uses that file or not, so I couldn't troubleshoot it from that aspect. Any help would be appreciated.
