Remote access configuration on SRP527W

Hi,

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"

    - Type: Single Port Forwarding

    - External Port: 3388

    - Internal Port: 3388

    - Protocol: TCP and UDP

    - 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.

Thanks,

I found the reason by myself.

When I add "Port Forwarding Entry", I made a mistake.

it's original configuration.

    - Type: Single Port Forwarding

    - External Port: 3388

    - Internal Port: 3388

    - Protocol: TCP and UDP

    - IP Address: 192.168.0.25

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.

Thanks anyway.
