This "Router" will act as an ISP core router doing Routing Only! I wish to protect the box itself, while it preforms it's duties as a Router allowing only ssh from the ip's that I wish for management. This way I can also setup rules to protect it form DOS attacks etc... Now I have been thinking of this, but I can go two ways: 1. Making it harder than it really is -OR- 2. Allowing it to be so easy it is not secure. So any suggestions would be great. Thanks! Mark marks@crvinc.com
