Enable Reynolds & Reynolds SDC Server

Here's the information that you'll need to enable a Reynolds & Reynolds Linux server to communicate through your ISA 2004 Server. If you support auto dealerships, you know what I'm talking about. Ignore the comment that you've probably gotten from R&R that they can't work behind an ISA server.

First, make the R&R server a SecureNat client buy assigning it a static IP address and setting its gateway and DNS to the Internal NIC address of your SBS server. Create an access rule and place it above the SBS Internet Users rule. Create the rule such that traffic will flow from the R&R server to External allowing only the protocols listed below. Then, apply the rule and have R&R test. Everything should work flawlessly.


· TCP port 80 HTTP

· TCP port 443 HTTPS

· TCP port 53 DNS

· TCP port 20 / 21 FTP

· TCP port 23 TELNET

· TCP port 25 SMTP

· TCP port 110 POP3

· UDP port 123 NTP (National time protocol; this should be set up for both outbound and inbound)
