Newbie question about HTTPS and WCF

Can anyone help me out setting up https to work for my WCF web service? The web service works great on HTTP, but when I turned on HTTPS I cannot get it to work... I've tried to do some changes in the web.config but nothing works... here's a part of my web.config what do I have to change to make it work....

<system.serviceModel>


<netTcpBinding>

<readerQuotas maxDepth='32' maxStringContentLength='8192' maxArrayLength='5242880'
maxBytesPerRead='4096' maxNameTableCharCount='16384' />
<reliableSession ordered='true' inactivityTimeout='00:30:00'
enabled='false' />

<security mode='None' >

</security>
</binding>

</netTcpBinding>
</bindings>
<client>
<endpoint address='net.tcp://192.168.0.121:8001/SecureDownloadHost'
binding='netTcpBinding' bindingConfiguration='NetTcpBinding_ISecureDownload'
contract='SecureDownloadHost.ISecureDownload' name='NetTcpBinding_ISecureDownload'>
</endpoint>
</client>

<serviceBehaviors>

<!--<serviceMetadata httpGetEnabled='true' />-->
<serviceMetadata httpsGetEnabled='true' />
<serviceDebug includeExceptionDetailInFaults='True'/>
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service behaviorConfiguration='SecureDownloadBehavior' name='SecureDownload'>
<endpoint address='https://downloadmanager.pixellogo.com/Services/SecureDownload.svc' binding='basicHttpBinding' contract='ISecureDownload'/>
<endpoint address='https://downloadmanager.pixellogo.com/Services/mex' binding='mexHttpsBinding' contract='IMetadataExchange'/>
</service>
</services>
<serviceHostingEnvironment>

<add prefix='http://downloadmanager.pixellogo.com/'/>
</baseAddressPrefixFilters>
</serviceHostingEnvironment>
</system.serviceModel>

 

Any help would be greatly appreciated....
