I see the same behavior when installing Tomcat 5.5.33 (Core) on Windows 7 32
bit. Without changing anything in the config nor other Tomcat files, after
starting Tomcat, http://localhost:8080/ works, whereas
http://192.168.0.4:8080/ (the LAN IP) does not (Connecting to that port
fails). Note that also http://127.0.0.1:8080/ does not work.

>From looking at netstat, it looks like Tomcat is only binding to the IPv6
addresses, but not to IPv4 addresses, so http://127.0.0.1:8080/ can't work.
Netstat's output for the Tomcat process ("ABHÖREN" means "LISTENING"):
  TCP    [::]:8009              [::]:0                 ABHÖREN         3028
  TCP    [::]:8080              [::]:0                 ABHÖREN         3028

The default installation of Tomcat 5.5.33 uses Tomcat Native 1.1.20. After I
remove/rename the tcnative-1.dll in Tomcat's bin directory and restarting
Tomcat, now Tomcat binds also to IPv4 addresses and http://127.0.0.1:8080/
(and the variant with the LAN IP) works.
Netstat: 
  TCP    0.0.0.0:8009           0.0.0.0:0              ABH™REN         3596
  TCP    0.0.0.0:8080           0.0.0.0:0              ABH™REN         3596
  TCP    [::]:8009              [::]:0                 ABH™REN         3596
  TCP    [::]:8080              [::]:0                 ABH™REN         3596

With Tomcat 7.0.20 (using TC Native) and without changing anything in the
config, it seems to only bind to the IPv4 addresses, but no IPv6.
  TCP    0.0.0.0:8009           0.0.0.0:0              ABH™REN         2864
  TCP    0.0.0.0:8080           0.0.0.0:0              ABH™REN         2864

When using Tomcat 7.0.20 (without Native), it binds to IPv4 as well as IPv6
(like Tomcat 5.5.33 without Native).


However I could get TC 5.5.33 to bind on the IPv4 address, by adding the
"address" attribute to the <Connector> element in server.xml. Maybe you
could try this and see if it solves the problem?

    <!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
    <Connector port="8080" maxHttpHeaderSize="8192"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" redirectPort="8443" acceptCount="100"
               connectionTimeout="20000" disableUploadTimeout="true"
               address="0.0.0.0" />


However it seems a bit strange that TC 5.5.33 is only binding to the IPv6
addresses by default/using Native.
