ProxyRemote does not work

Hi,

we have 3 hosts, all redhat 8.0
host1 with apache 2.0.40 external net 80.228.x.x
host2 jboss-3.0.7-tomcat-4.1.24 internal net 192.168.x.x
host3 postgres internal net 192.168.x.x

On host1 in httpd.conf I added :

------------------------------------------------------------------
<IfModule mod_proxy.c>

ProxyRequests On

<Directory proxy:*>
Order deny,allow
Deny from all
Allow from 192.168.2.
</Directory>

ProxyRemote * http://192.168.x.x:8080/isa/autoanzeigen/start
ProxyRemote http http://192.168.x.x:8080/isa/autoanzeigen/start

</IfModule>
------------------------------------------------------------------

But it does not work,
connections from 80.228.x.x to 192.168.x.x on port 8080 are allowed.

Can anyone help me ?
