title: Apache on Solaris 11: connection from localhost works, remote host's connection gets reset by peer
body: <p>I have configured an apache2 server on Solaris 11, which seems to work well since it shows the correct behaviour when I access it on localhost. However, any remote connection is reset by peer. I already disabled the ipfilter firewall to no avail. A telnet connection from a remote host on port 80 works fine, though:</p>
  
  <pre><code>$ telnet myserver.com 80
  Trying xxx.xxx.xxx.xxx...
  Connected to myserver.com.
  Escape character is '^]'.
  GET /
  &lt;html&gt;&lt;body&gt;&lt;h1&gt;It works!&lt;/h1&gt;&lt;/body&gt;&lt;/html&gt;Connection closed by foreign host.
  </code></pre>
  
  <p>With curl I run into this "connection reset by peer" error:</p>
  
  <pre><code>$ curl http://myserver.com
  curl: (56) Recv failure: Connection reset by peer
  </code></pre>
  
  <p>I'm totally out of ideas where to look for a fix... Any hint is highly appreciated! The configuration of the server's operating system is an "out-of-the-box" installation, as is the Apache installation (although I use the apache from openCSW, but this didn't make a difference). Is there any security context which filters http connections from remote hosts where I could have a look at? Thanks for helping!</p>
