I am using a couple of Barix sets. One has the streaming firmware, with the public IP address at the Instreamer location. The other is using the STL firmware on a T1 line. I am having no problems with either of these. I am attempting to set up a third Barix pair. In this case, the public IP address is at the Exstreamer location. So far, we haven't had any success. But, I haven't had time to really research this. If anyone can give me some quick tips to at least get me in the ballpark for a setup that will work, I would appreciate it. There doesn't appear to be a network issue. The person at the Instreamer location can log into the Exstreamer. Thanks.
