Simon If you are using 255.255.0.0 as your subnet then every device will be able to see everything on the 172.20.x.y network.
No need for static routes or anything. -- Martin Hepworth Snr Systems Administrator Solid State Logic Tel: +44 (0)1865 842300 > -----Original Message----- > From: Simon Delicata [mailto:[EMAIL PROTECTED] > Sent: 06 March 2006 15:06 > To: [email protected] > Subject: [gb-users] Backbone for my server > > Hi all, > > I hope someone can advise, before I make an almighty cock-up.
