SBS 2003 ISA

Hi. I have SBS 2003 Premium running with one NIC. All Internet is done directly to the router. Exchange is not running. I have one workstation that does an overnight FTP download and 3 RWW workers. I would like to add an NIC and run ISA. The SNS 2003 is the old version with SP1 done the hard way :)
What do I need to watch out for?
Thanks
Nick

Mainly it breaks down into two or three areas.
Once you've added the second nic, make sure only the external nic has a default gateway pointing to the external router, the inside nic must not have a gateway. Use a different subnet for the external nic to the internal subnet.

Make sure you rerun the configure email and internet connection wizard after its installed and the remote access wizard as well. (Basically make sure you run the wizards to set everything up rather than do it manually).

Make use of the ISA firewall clients - makes life a lot easier if you only have sbs2000 and the original ISA version

Nick,

You'll find a sample configuration diagram here:  http://sbsurl.com/twonics

Did you order the ISA 2004 CD from Microsoft though?  You'll need that if you want to have the current version.  It's included as part of the SP1 upgrade.  Unfortunately though, the CD is temporarily unavailable -- per the notice on this page:  http://www.microsoft.com/windowsserver2003/sbs/downloads/sp1/default.mspx  you'll have to wait until the end of the month.

Instructions for installing ISA 2004 are included in this document: http://download.microsoft.com/download/c/a/b/cab5c8cd-d0f9-4b37-93c3-f36d976c86a2/PremiumInstallSteps.htm

The original Dell SBS 2003 Pre SP1 disks that I have (OEM) include ISA server.
Just to confirm, SBS 2003 Premium. Can I not use this?

10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

Then it came with ISA 2000.  If you want to upgrade to ISA 2004, which I highly recommend because it was a total rebuild of the interface, then you need to order the media as posted above.

Bit miffed there as that was not the question asked but so be it.

Yep sorry about that. I awarded the points because of the time the answer would have saved me. As I didn't install ISA from the disk BEFORE doing the SP1 shuffle I would have been installing a pre SP1 ISA, presumably then having to do the whole (pain in the ***) SP1 thing again. I understand the new versions of SBS with SP1 integrated are much better. Thanks for your input though. I did know the things you mentioned but was looking for the pitfalls.
 Kind Regards
Nick
