Internet-Ethernet and Local Net

[Ioannis]

I am trying to connect a PIC controller with RS232-to-Ethernet adapter to the internet so I could read data from a remote PC.

The set up is as follows:

1. PIC with Serial com.
2. Serial to Ethernet adapter
3. Local Network with 8 port Switch and a DSL Router with 4 ports. My switch is connected to one port of the router.
4. Local PCs
5. Dynamic IP DSL Internet connection.

On the local ethernet everything is OK, naturally. I see all PC's and of course the PIC.
But I cannot acces the PIC over the Internet. I know that dynamic IP prevents this, but have tried with www.dyndns.com to create a virtual domain with no luck.

All I managed was to access my DSL modem from the remote PC which was the expected thing as I can understand.

How can I overcome the DSL router and see what is behind it on my local net?

Thanks,
Ioannis

Have you enabled Port Forwarding on your Router?

Hi Ioannis-

My ISP allows me to register a static sub-domain address, which gets around the problem of a dynamic IP address

Quote from my ISP (www.Axxess.co.za):

"No static IP address? No problem! vIP DNS will make your computer(s) accessible anytime, anywhere by associating a static sub domain to your dynamically changing IP address"

Suggest that u check with yr ISP to see whether they can do the same. Greece must be more with it than South Africa!

Paulwoody is right. You need to set up port forwarding on your router so when a request comes in, it gets routed to the proper IP address on your LAN. I use dynDNS so I can see my parallax PINK module from anywhere on the net. Works great.

Thanks for the replys. I did not knew about port forwarding. Do all modem/routers have this option?

Mine is a DSL-584T D-Link type. I will search for this.

Thanks again.

OK. I think I got in part. Look at the attached gif. I don't know what to set at Gateway. Has this something to do with the Device itself?

I'm not sure if all have that option, but I would think Dlink would. I'm using a Dlink router. A quick look at the tech spec for this says" Packet filtering based on port, source IP address,
destination IP address, MAC address (ICMP/TCP/UDP)". Which sounds like it to me. On mine, you set up the port forwarding in the web page in the router for all of the settings.

I think the screen your in is for a Static Route. I take back what I said earlier.... I'm using a NetGear router. Here's what mine looks like.
