Subject RE: forward request by changing the port in request url
Date Thu, 13 Jun 2013 23:22:09 GMT

I do not think destination NAT is good solution because it works on TCP
layer and knows nothing about domain names and URLs (both are application
level (http) knowledge). So you would need to use separate  IP/port  for
that and in case you have it you can bind tomcat there directly) So
application-layer forwarding proxy (nginx, squid, apache) is way to go.

Hardware cisco solutions could handle it too but I they are too big  for
such a simple task (unless you have really many users)
