Can't Connect Over 3G

[xmarltonx]

So far this has been a nightmare. I can connect perfectly when I am in the network however when I attempt to connect via 3G, no dice. I know its something with my settings.

I do not have a static ip, I have a dynamic ip so I'm under the impression that I need to set up a way for this to work. I have created a free account with dyndns and a domain. I have even entered this domain in the app along with the appropriate port.

I believe my issue is in the port forwarding. I have a linksys wrt54g and opened the correct port however I can't seem to forward it to the correct location which will contact dyndns to obtain my ip thus granting me access to my mac.

It's driving me up a wall since I'm very good with this stuff, but with networking not so much. I almost caved and nearly purchased log me in but I am determined to learn this.

Any and all help is appreciated! Thanks =)

I personally use the tomato firmware with my wrt54g, and it works a treat.
In the port forwarding in your wrt, port forward from 5900 to 5900 and use the internal IP of your machine inside your network.

You can also test your port forwarding here:

That seems to be my one problem. While trying for forward ports through the router's configuration webpage, theres no way for me to specify an IP address. I have a field that allows me only to change the last 3 numbers =(

3G doesn't allow 5900, you need to open 143 (IMAP) whish is an open port on most of the 3G carriers.
source 143 to destination 5900.

And setup port 143 in Remoter VNC.

The last three number is all you need, as you're specifying the internal IP Address of your machine, and the other octets are the same for all hosts in your LAN (192.168.0 or 192.168.1)

About ports being blocked, I guess it depends on the carrier. In the US, AT&T doesn't block any ports, so 5900 is fine.
