T3   Troubleshooting Firewalls
Char Sample, Consultant

Who should attend: Systems integrators; firewall administrators, support personnel and managers; anybody who either presently runs a firewall or plans to implement one in the future.

Now that your firewall is installed (perhaps by someone else) how do you deal with the problems that will almost certainly come up? This tutorial focuses on the tools and techniques used to solve the most typical problems that occur after the installer has left.

Topics will include:

	DNS
	Sendmail
	Routing
	Subnetting
	Load sharing vs. load balancing
	Access control lists
	Authentication
	VPNs
	Logging and reporting
	Operating system nuances

This tutorial provides a list of some of the more common firewall problems, behavior associated with those problems, troubleshooting methods and the all-important solutions. The slides from this tutorial can be used as a reference guide in firewall problem solving.
