Melbourne DSL connection- iSeek provide microwave link to Edward St, Brisbane

- Optus provide DSL tail- RequestDSL to provide ANOTHER DSL connection to Melb office

Dialin/Dialback- 8 modems

- Dialback preferred for security- 33600bps. No 56K upgrade planned- will supplement CiTR CA

Areas needing improvementCitron

- I/O performance hindered by bad disk layout- Single 100Mbps ethernet port

Internet Reliability- No backup routes on a UQ failure- SPOF on microwave hardware

Printers- Duplex jamming problems- Speed issues

Timesheet System- No email submission - why?

Coming Soon...CiTR Certificate Authority

- Windows 2000 Server based- VPN assist from 3rd party ISPs- Supplement dialback system- Perfect for roaming users

VPN tunnel upgrades- IPSec rather than GRE format- Improved security

Citron I/O upgrade- Better disk layout- Improved performance- Complex task, Juggling of data

Any Questions???
