Port mapping and bridging   18 October 2016, 05:08

Hi,
I have BWM installed to my PC (Windows 7). Everything is working fine, the only problem I'm having when I do remote desktop to my client server: it seems as if there is something blocking the connection, please help me.

Did it work before installing BWM?

Please provide more details as where you are trying to connect from, where to and what's happening.

OK Andrew, its the first time I have a client needs to do remote desktop to his server. He wants to connect from outside to his server, he is getting the internet from me wireless. I did DDNS and port forwarding on client side but the traffic is getting blocked to my server. He got internet access but we failing to dial in remotely. Please take me step-by step on how to do port mapping because I think there are some settings I need to do on my server where I installed BWM. If its possible can you login via teamviewer to my server .

Let's start with diagram and assume your network looks like this:

<Client server> - <BWM Server> - <Router> - <Internet>

This also assumes your client's server doesn't have a public IP address. In that case, the client would connect to port X and your router's IP address. You will need to configure the router to pass traffic from port X to the server's IP address.

Then if the server was connected directly to the router, that'd be all. However we also have to pass through BWM server - if you are using bridging, that would be automatic. If you are using RRAS or ICS, you may have to configure the router's port forwarding to send data to the BWM server instead and from there you can forward it to client's server.

The easiest solution though is to tell the client to use Teamviewer instead - it works behind NAT and doesn't require port forwarding.

You have to tell me what your network looks like, what is connected to what and how it's configured. I am afraid I can't just blindly push a button and make everything work.

The BWM server is connected to mikrotik router and the second card connected to Ethernet switch then to clients

That's better, now please provide more info on:
  1. How you have forwarded a port for RDP on Microtik - it's best to attach a screen shot.
  2. How you route traffic between Local Area Connection and Local Area Connection 2. Using ICS - Internet Connection Sharing?

Re: Port mapping and bridging   19 October 2016, 18:51

yes I used ICS to route traffic between Local Area Connections

In this case, as you are not telling how and if you configured Microtik appropriately, here is how to configure port forwarding with ICS. It is not related to our product by the way - you will need to make your own research on how to configure it.
