There are a few options in addition to running two instances of Tomcat.

1) Use virtual hosts to separate the requests; one <Host> per IP address.
http://tomcat.apache.org/tomcat-7.0-doc/virtual-hosting-howto.html

2) Use a filter in each webapp to reject requests sent to the wrong IP addr=
ess.  This one is fairly easier to configure:
http://www.tuckey.org/urlrewrite/

3) Write a single <Valve> at the <Engine> level to reject inappropriate req=
uests.  I don't think there's a standard Valve to do this, but it should be=
 fairly easy to extend an existing one.
http://tomcat.apache.org/tomcat-7.0-doc/config/valve.html

4) Configure two <Service> elements, each with one <Connector>, <Engine>, a=
nd <Host>.
http://tomcat.apache.org/tomcat-7.0-doc/config/service.html
