I can normally run MAMP on my Macbook and then debug mobile devices by connecting to, for example, http://192.168.0.xx:8888. Our network has changed slightly now to a Technicolor TG582n WIFI router and now my connection to that address is very intermittent, not working for the majority of the time.
I checked the router's logs and it is logging the following after a failed (server not responding) attempt from the mobile:
FIREWALL replay check (1 of 4): Protocol: ICMP Src ip: 192.168.0.66 Dst ip: 22.214.171.124 Type: Destination Unreachable Code: Port Unreacheable
192.168.0.66 being the IP of the Macbook I'm trying to access via the mobile. My DNS settings on the Mac use Google's public DNS of 126.96.36.199 so that's possibly where that destination IP is coming from.
Any idea how to make this resolve properly? Ideally I would want to have the Mac always connect to the router via the same ip, eg 192.168.0.99 as I guess a fix here will involve some kind of port forwarding and it would change each time the Mac's network IP changes which it tends to do every day after it reconnects. I've never had this problem before on all the other routers I've done similar... I'm out my depths at how networks work here to fix this!
