No. You've effectively allowed anyone (that bypasses your "router") unfettered access to the services running on these systems.

No single device is a silver bullet for network security.

I'd like to suggest you invest some time in the following documentation: http://www.tldp.org/LDP/nag2/index.html http://www.tldp.org/LDP/sag/index.html http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/custom-guide/ http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/security-guide/ http://www.oreilly.com/catalog/tcp3/ > Thanks a lot for your help.
