Looking to offer a fallback internet access scenario in SBS2003 network.
The setting is
>Comcast Internet Modem
“Network” being (1) a wireless access point with half a dozen laptops, (2) NAS, (3) printer.
I want to continue to provide Internet access (albeit without the access to Exchange/email) in case the SBS 2003 box goes down. SBS 2003 contains DC, DHCP, DNS, ISA, etc. As there are no significant fluctuations, the DHCP leases are sufficiently long (7 days) to survive normal downtime for reboots, etc. A DNS is available from the ISP.
Ideally, I would NOT want to configure static settings in the client TCP/IP settings to point to the SBS 2003 DNS with ISP DNS being secondary but leave client settings dynamically.
With all that said, what’s the best way, if there is any, to implement an “escape route” out of the network for pure internet access?
Should/Can I have a second router between the Cisco router and the switch to allow for a second gateway out of the 192.168.0.x network, in parallel to the SBS box?
With above, how do I avoid to have traffic take the shortcut as long as the SBS box is available?
What is the best (or at least a professional) practice to address this?
I’m happy to add/exchange modems, switches, etc. with the right technology to make this work but I wish I knew where best to go.
Thanks in advance..... J
