Comcast just installed a new Cisco Business Modem (Model: DPC3939B) at a clients office and I went in to set up the port forwarding for 3 machines that use remote desktop to access their machines at night. On the old system I could just set up
Name Public Port Private Port Protocol IP Address
RDP1 3389 3389 TCP 192.168.1.101
RDP2 3390 3389 TCP 192.168.1.102
With this setup, the user could enter something like dyn.getip.com:3390 and they would be directed to the 102 IP address
With the new business router, it asks for
Service Name Type Start Port End Port ServerIP Server IPV6 Active
I tried
RDP1 TCP 3390 3389 192.168.1.101 chk
But it tells me that the end port must be equal to or less than the start port. So it appears that this is a port range where I want to specify a port that becomes 3389 to access rdp. (I'm really not wanting to change the default for all the machines as win7 requires firewall changes and such and seems to glitch at times when doing this)
I then though I might need to set up something in port triggering but when I tried
Service Name: rdp_1
Service Type: TCP
Trigger Port From: 3390
Trigger Port To: 3390
Target Port From: 3389
Target Port To: 3389
It just responds with: Failure! Please check your inputs
Can anyone enlighten me on what I need to do to keep all machines at their default 3389 port for RDP but specify a port in the connection address?
Thanks.
