EDIT: This sums it up pretty nicely --> Cannot access LAN with WAN address from within my LAN Thanks for the feedback, everyone. Original Post: I'm pulling my hair out over this one... I've got a Windows 10 (build 1903) machine running the latest Blue Iris (v5.x) sitting behind a Wave 2 router provided by Spectrum. From the local LAN/WLAN, I can access the BI system via iOS app and browser, but I cannot access it using the WAN IP:8080. When I'm off-site, I can successfully access the system through the iOS app and browser using the WAN IP:8080. This tells me the port forward for 8080 is working, right? Note: I was not able to test from LTE while on-site because the cell reception was not sufficient. Why would attempts to access the remote address from the local network result in the connection being refused? I feel like I've encountered this before but my old brain can't remember what the fix is/was. Note: I have the same issue connecting to RDP while on the local WLAN/LAN using the remote address. Thanks!
