Port 80 problems with WCF and possibly Skype

Question

Found this which may explain some of my problems - MSDN Post

I have written a wcf service hosted inside a console application. I then have a client that interacts with the service.

The client and service work fine on my machine.

When I move the client to another computer, I can get it working but I have to turn the firewall off on both the server and client machine ( im assuming I can fix this just by opening the firewall ports that the service eventually need to communicate with?) but I also have to turn skype off otherwise I get an "could not register URL http://+:80/temporary_Listen_Address/ ......" "the process could not access the file because it is being used by another process".

I have read some stuff about changing the client base address but could not get this operating. I may however be missing something else. I have a feeling I should be changing the endpoint address in teh client config when I move it to a different machine to my own, but this broke the setup so I left it unchanged.

Here are my configs.

Answer 1

In the client application configuration, edit the binding to include clientBaseAddress attribute.

Below is the sample clients' binding configuration

 <bindings>
   <wsDualHttpBinding>
    <binding name="wsDualHttpBinding.TimeService" closeTimeout="00:01:00"
        clientBaseAddress="http://localhost:9090/WCF.ServiceClient.TimeService/">
    </binding> 
   </wsDualHttpBinding>
</bindings>

Skype has settings to disable the usage of port 80, check skype options. So skype and your service can co-exist and work!

Answer 3

Your endpoint address must match machine/port/protocol of the server. Your endpoint in the example hits port 8080.
