2. Agenda
Review
Status
Issues
Discussion

3. Review Concept: campus-wide private addresses Motivation:
campus == UWS + UWT
private addresses: 172 range from RFC1918
cross-subnet routing, to/from UW public addrs (but not to/from the Internet)
Motivation:
Address conservation
Reduced external exposure/visibility
Option to limit default connectivity
Not a replacement for Logical Firewalls

4. Status Routing enabled in most places Split-view DNS operational
DHCP private-address subnet option ready
Usage to date:
Approx 15 requests
Nebula: plans to use for all printers
Beginning Phase II: exploring partial Internet access options

5. Issues Global NAT option: still problematic
Need feedback on alternatives:
Simple Web proxy?
Local NAT boxes?
Other??
Current IETF debate on IPv6 “site local”

6. Discussion / Q&A My Panel of Experts: Marc Hudson: P172 project lead
