I am having trouble accessing Fiddler on my laptop from other devices. The laptop runs Windows 7 Enterprise, and one device I'm trying to connect with is an iPad using iOS 8.4. When I'm at work, I can easily connect to this laptop. I have "allow remote computers to connect" checked, and I use the default port with the local IP set as the proxy on the iPad. It works well. When I take these two devices home, however, I can't even pull up the Fiddler Echo Service page by going to http://laptop:8888 (ie laptop is 192.168.1.9). I can use a ping app on the iPad, and I get a successful response by pinging this same ip on port 23. I've confirmed that Fiddler is still set to listen on port 8888 and rechecked the local ip of the laptop many times. I've removed proxy settings on the iPad's wifi connection, so it's not trying to connect to the local ip from the office network. The proxy settings on the iPad are blank when trying to reach the Fiddler Echo Service page of the laptop. No settings on the laptop have changed from when it was at work.
I started thinking maybe there was a router issue, but I can run Fiddler on my desktop and have the iPad connect to it after adjusting the wifi proxy settings, and the laptop also reaches the desktop's fiddler echo page. I have not setup any port forwarding for the deskptop in my router.
Is anybody able to point me in the right direction to get other devices to connect to Fiddler running on the laptop? I'm completely out of ideas on what could be the problem. The only thing that has changed is the network these are on, and I've tried changing the wifi proxy's settings to the correct, new local ip of the laptop on the home network, and other devices on this network are able to accept traffic through Fiddler.
Any help is greatly appreciated!
