DSR 250 / Port forwarding issue
« on: September 29, 2020, 08:12:23 AM »

Hi All,
At my site we have few electronic systems connected by Ethernet. My old TP-link router did the all necessary job and port forwarding as well. During the renovation of IT system, we have changed the old TP-link router on the new DSR 250 and I got an issue with port forwarding.
Router: DSR 250, Firmware: 3.14B103H

My internal equipment sited on IP:
Communication port: 80

At the DSR 250 I want to use port 8095 for the forwarding to IP port 80

My settings in Security section:
Custome Service Configuration

- Name: ConrWebAccess
- Port Range
Source Start Port: 1
Source Finish Port: 65535
Destination Start Port: 8095
Destination Finish Port: 8095


Firewall Rules Configuration

Service: ContrWebAccess
Action: Always Allow
Source Hosts: Any
Lag: Never

Destination NAT Settings
Internal IP Address:
Enable Port Forwarding: ON
Translate Port Number:80

But unfortunately I donít get result.
Maybe I have missed some checkmarks or other restrictions?
I will appreciate for any help or advise with my case!
Many thanks!

Is the device that is using configured for port 80? If so change it to 8095 on that device. Also recommend upgrading the DSR-250 to latest firmware depending on what hardware Rev you have.
