I've been trying to test ThingParkCommunity with my Conduit IP67 BS, but after I got to connect it to TPC it displays a "Radio Error" message, I've read other topics in the forum and I think it may be that ports 21 and 22 are not open on my network. Right now, I can't manage to open them because it takes some contract and cost variations with the ISP. Is it strictly mandatory to have those ports open for the gateway to connect with TPC? If there's another way to do this, can you help me with that?
