Discussion: Gathering Data for Designing
Network Connectivity

What data needs to be gathered for designing network
connectivity?

Reasons for Using Routers

Use routers to:
• Isolate networks from each other
• Provide a start for a secure network
implementation
Traditional uses of routers
• Connecting WANs
• Segmenting LANs

Discussion: Considerations for Selecting an
Appropriate Network Device

What should be considered when selecting a
network device?
Internet Connectivity Requirements
Internet connectivity solution requirements:
• Scalability and fault tolerance
• Filtering
• Access control
• Bandwidth control
• Time-of-day access
• Security services
• Monitoring
• Application support
Using Packet Filters to Create Security Zones
Packet filtering on Windows Server 2008 routers is:

– Not performed by Windows Firewall
– Configured in the Routing and Remote Access administrative tool or netsh
– Stateless as opposed to stateful
– Can coexist with Windows Firewall
