I have an SBS box (not ISA Server version) with 2 NIC's External is 192.168.1.200 (router on 192.168.1.1) Internal 192.168.16.1. I should say right now everthing works fine on this box including all remote access:-) This company have just had a VOIP telephone system installed which needs access on port 4000 through to the VOIP server on 192.168.16.201 (which has been set as static).
They have a single static IP address from the web so when a request comes in on port 4000 how do I get it directly through to that VOIP server? I have allowed access through the Broadband Router on port 4000 to the SBS box on 192.168.1.200, I have re run the internet connection wizard and opened port 4000, but I guess the part missing is to tell SBS, send port 4000 requests to 192.168.1.200
Can anybody help?
