Ok, trying to grasp this port forwarding concept.... I think I am getting there... So If I manage to successfully port forward or DMZ one of my ezb4 using tcp 23 and 24... I can then run a copy of ARC anywhere in the world... type in my 192.168.225... yada, yada ip address of my ezb4 into the connection control dialog box in ARC and that should connect me remotely to my ezb? Do I have this right?

@Richard, Pretty much yes. You would need your external IP though, so 73.182.39.231 or something along those lines. I use a DDNS service on my LG NAS which basically allows me to use a url such as myusername.lgnas.com rather than my IP address, it makes it so much easier.

A lot of IP cams have DDNS services available too, or there are some paid for ones you can sign up to.

Not a requirement if you have a fixed IP but mine isn't. It doesn't change often but it does change.

So, to summarize;

1. Set your router to give a fixed IP to your EZ-B V4, i.e. 192.168.0.10
2. Forward ports 23 & 24 to the IP of your EZ-B V4 (methods will vary depending on router)
3. Check the port forwarding worked by visiting a website such as http://www.canyouseeme.org/
4. On a different PC outside of your LAN (or your mobile phone not connected to WiFi) pop in your external IP or DDNS URL in to the connection dialogue (don't forget the :23 after it)
5. Hit connect
6. Enjoy controlling your robot from anywhere in the world!

1. Done
2. Done (I think anyway) with dlink router not the SMC modem
3. Won't open my IP address (which when I type into my web browser brings up my SMC modem login screen)

Question, I port forwarded my new router (dLink), but do I need to do something with my old router (SMC model) which I disabled the wifi on, but I am using the modem part of it? The (my) remote IP address that comes up in the link above is that of my old SMC router/modem... I get an error when trying to check if port 80 (tried 23 too) is open... "cannot see your service on port 80"

Ok, opened port 80 on my smc modem/router and not htat web site you gave me reports port 80 as open....

Ok, now I got port 23 open (confirmed on http://www.canyouseeme.org/).... should I still be able to connect to my EZB on my home network using my remote IP address (with : 23 at the end)? Because I can't... and I won't be able to try it on another network until my girlfriend gets home tonight where we can try it on her mobile phone network...

Richard, please tell me every device that you have connected from where your internet connection hits your house to your EZ-B. For example, for me it would be Cable Modem, Firewall running BSD, Switch, Wireless Access point and then EZ-B. This will help me to understand the network and be more able to help. It might just be modem and then EZ-B.

Thanks

Port forwarding wont prevent you from accessing your device on your local network. It will just allow you to access your device from outside your network. Inside your network, you would use your 192.168.x.x:23 address to connect to your device for fastest response. Outside your network you would use your public IP address:23 to connect to your device.

While it would be possible to connect to your external ip address:23 when connected to your internal network, it would make a couple more hops to find the device. It sounds like a routing table in the router got messed up. This can be cleared by rebooting the router/cable modem.

Also, it may be necessary to clear the cached routes on your computer. This would be done by going to a command prompt and typing (each is its own command with enter hit after each line) ipconfig /release ipconfig /renew ipconfig /flushdns

If you are using a phone, I dont know how that device would release a renew its network connection other than a reboot of the network.

A video of this setup procedure would be incredible.
