internal Yes, external No,

I can reach Vibe streamer with another computer on my network by typing in the internal IP address and8081. But I Can not do this through the internet at another location with my external IP address. Strange thing is, I can access my router from another location with this external IP address .

Your router probably has remote access enabled. You still need to add port forwarding to the PC running VS as I describe in your other thread http//www.vibestreamer.com/forum/viewtopic.php?t=675
