How do i configure my router (SMC Barricade 7004-ABR) to work with TOMCAT.
The Baricade has a management interface that you access through a web browser. The document that came with your router or the information on SMC's web site should walk you through the change.
In short you need to allow people connecting from the internet to access your tomcat system on the port your running tomcat on. You can also call SMC support if you need someone to walk you through it.
