What sites + what ports needs to be reachable for the signing tool C:\Program Files (x86)\Skyline Communications\Skyline DataMiner Protocol Builder\SLDMProtocolBuilder.exe

Our security department is very severe.  Now they have implemented segregated networks. The build server is cut off of the outside world.  But for the Skyline signing tool this build server needs to have access.  They want only give access to the bare minimum.

They gave the build server access to

www.skyline.be

protocol.skyline.be/api/Soap.asmx

But this is apparently not enough.

Please give me a list of sites and ports the signing tool needs, because it has to pass a waterfall of authorities to allow access (American style apparently) and in the mean time no new DMAPP can be build => customers cannot get their fixes,...
