Please someone help me with this. I have tried everything, and cannot get this to work. Can someone tell me how to conbfigure the firewall so that rdp will work. My setup is basic:
linksys wireless router with dhcp disabled
Untangle is in router mode with dns and dhcp enabled. everything else is working fine. I have removed the packet filter per someone's advice. But I attached the settings I have so you all can see how I have things configured.

have you forwarded your port on the router?

the rdp program knows that will work on that port.did you change the port on the program?

check firstly if the default port works and tell me why you want to change the port, for security reasons?

First let me thank everyone for their input. Now I will address everyone's questions: I did not think I needed to forward the port on the linksys router, because I am not using it as a router; the untangle server is doing the routing. I will go ahead and forward the port on the linksys and see if that helps. Before I installed the untangle server, I was able to rdp perfectly, even with the changed port number. I changed the default port as an extra measure of security. I changed it back, and was still not able to connect. As mentioned before, I will forward the linksys port and let you know if that helped.

Well, I forwarded the ports on the linksys, it did not resolve the issue. Please view screen shots from my prior post to look at my settings.

listen dear Zay
I have check you thread really carefully and I wonder here if your linksys doing any NAT which is probably does and if UT is your router you have second NAT in there, in this case you have to have extra destination port rule on linksys.
I don't know how your configuration it is now but I m trying to guess.........
so .....scenario number 1
set UT in linksys DMZ so all incoming traffic goes there without any extra setup and your port forwarding rules you got there will work.
so .....scenario number 2
replace linksys with UT and set your linksys act as a Access Point and put it on your switch behind UT with fully security.
BUT still I do not like changing ports on RDP program , just leave it as it is.
if you change it with a good port scan a good hacker will find out that you have change port on that specific service, already the whole forum know about it :lol
waiting your response

remember that the best solution is to connect via client vpn on UT box, that means zero configuration.

Thanks for the tip and response Masex. NAT on the linksys is turned off, and the linksys been functioning as just an access point for my wireless. The only step left for me to do is to create a dmz in the linksys that points to the UT. per someone else's advice, I turned on port forwarding on the linksys as well. I had also revert back to the original port number for rdp. I will set the dmz and let you know if that worked. Did you look at my screen shots? Are my configurations correct? (screenshot is before I changed back to default rdp port, so number is changed back now). I await your response, and thanks again.

Your UT has just an external and internal interface, and your Linksys router is internal right?

What if you uncheck the ICMP and remove the NEW PORT OPTIONAL?

Yaaaaaaaaaeah, all is well now. Actually it was working the whole time. I was so used to using my DDNS name that it did not occur to me to just use the IP. It dawned on me in my sleep (yes no life huh) that if I am able to successfully download the openVPN client, then something is working. This morning when I got to work, I looked at the link for the OpenVPN client download and decided to use that, and voila........I was able to get in. Now all I need to do is figure how to get the openVPN to work on my vista machine.
