Hi,
I’ve been able to create remote access to pc’s cameras and other devices behind a natted network/hotspot (RB750G) by using “bypass” mac rules with IP binding. and dst nat rules with “port forwarding”.
But, I cannot seem to enable “proper” remote access to a printer/scanner which saves documents to it’s hard drive. I can access the printer remotely with dst nat rule but i can not access the "document’s which the printer/scanner saves to it’s own hard drive.
Should I be using dst nat rule or do 1 to 1 net mapping?
Might it need UDP protocol and other ports opened?
Thanks,
try use wireshark to identify and capture data stream from your pc to printer
hopes this help
Thanks,
I loaded wireshark on a pc that’s local to the printer network.
I accessed that pc remotely via “windows remote desktop”
Attached is a pic of a packet capture from that pc.
If you’ll notice the “get” capture on line 872.
Documents are saved to the printers hard drive in /DH/repository/ folder. I guess it’s using http/1.1 ?
So, the problem is accessing the jpeg’s remotely. As one tries to do this. you can see the activity. It’s looking on the “local” ip of the printer (10.0.0.7) which I’ve statically assigned. So, I can access the printer/scanner remotely with http://public_ip:8050. And I’ve created the dst/nat rule with that port (8050) assigned to public IP, and port 80 to the local IP of printer (10.0.0.7)
But nada as far as getting documents off the printer remotely.
I believe if I were able to assign a “public IP” to the printer, it’d work.
Did a simple end-around fix.
I created a VPN to the printer.
