I currently have a fully functional SBS 2003 network running ISA 2004 as proxy, VPN access, OWA, Hosted Websites, Intranet and SharePoint Services.
I am in the process of setting up a R&D network with Mail Server and web server which is entirely Linux based to run similar services but on a difference network address. This is simple to achieve if I install a separate DSL line with static IP for the R&D network to access the Internet.
My question is can these services be achieved on the Linux network without the introduction of a second Internet connection and without disturbing the services on the current SBS Network? If so what devices or configuration is required? Please advise on options – Thank you.
