I'm using SRP527W router at the moment and there are 10 PCs in the office.
First of all, I'm not expert on network administration at all.
Anyway, I set up remote access for particular PC and it works good.
I made it like this.
Add "Port Forwarding Entry" in Network Setup > NAT > Port Forwarding menu.
- Type: Single Port Forwarding
- External Port: 3389
- Internal Port: 3389
- Protocol: TCP and UDP
- IP Address: 192.168.0.20
I need to set up another remote access for another PC (IP: 192.168.0.25).
I'm not quite sure I can use 3388 port for remote access.
However, I added another "Port Forwarding Entry"
- External Port: 3388
- Internal Port: 3388
- IP Address: 192.168.0.25
However, it doesn't work.
when I tested internal network(use private IP -192.168.0.25:3389), it works fine.
But when I tried through the Internet (use public IP 202.171.xxx.xxx:3388), it returns "Remote Desktop can't connect to ...." message.
I checked whether this 3388 port is opened or not with telnet.
I typed "telnet 202.171.xxx.xxx 3388" in command prompt, it couldn't be connected.
This means 3388 port cannot be reach through the Internet.
How can I open 3388 port in router administration colsole(Services Ready Platform Configuration Utility)?
Or is there any other way to set up another remote access?
Please save my life.
I found the reason by myself.
When I add "Port Forwarding Entry", I made a mistake.
it's original configuration.
The Internal Port should be 3389.
When I input "202.171.xxx.xxx:3388" on Remote Desktop windows,
this request will send to 192.168.0.25:3389 not 192.168.0.25:3388.
I missed this thing.
