DGL 4590

Has anybody been able to loop back? Meaning go out of your router and come
back in with your WAN IPort to get to your IPCAM to see if it works from
the WAN side? I can easily see the IPCAM with LAN side IP but not WANIPort.
Port forwarding is set up properly

Hi
Some Routers can do it,. most can Not. So if it is not working with your
Router. It probably belongs to the Most can Not category.

Thanks Jack,
I have worked on this for 3 weeks. I sure do find it hard to believe though.
How can anyone verify connectivity to their IP cams or servers on their LAN
from the WAN without this capability? I bought a high end router thinking it
had such a basic capability.

Assuming your router is capable of doing what you are attempting, you
need to consider how the ipcam can reply to connections from your lan
computer.

If the IPCAM and PC are on the same lan subnet, the router's initial
address translation and forwarding will work okay but replies will go
directly from the IPCAM to PC bypassing the router which can't then do
the required reverse translation.

Jim, thanks so much for reply. BTW: I meant DGL-4500.

The IPCAM is 192.168.1.210 my PC is .200. I can get to the IPCAM using
192.168.1.210 from my PC.
I bought this 'more expensive' router mainly because I need the ability to
readily assign an IP adrress to a MAC address. (Not just have the MAC address
be able to get an IP from the pool I assigned as available. Needed for port
forwarding.)
But I remember with less expensive routers I've worked with I was able to
enter my current WAN IP and port number and make it to the IPCAM. Without
that capability I can't confirm that I can get to the IPCAM from the WAN.
Everybody would have this same problem. This seems like such a basic required
capability. How can anyone set up LAN side servers and confirm connectivity
from the WAN? I can't imagine that we are expected to go to some other AP to
see if connectivity works! I have to be missing something here!!!

It's not impossible. It's just harder than it appears initially.

This link explains the problems and proposed solutions when using a
BSD box as a router. Although you are using a dedicated router, the
problems will be the same and the solutions or workarounds required
will be similar.
