Ip is different in port forwarding page

@XfinityVictor​ no, but for the purpose of logging the issue and solution:

1)server not accessible from external network. of course I check ip hasn’t changed due to windows. No changes.

2) check Xfinity app to make sure settings weren’t changed. Discovered the external ipv4 had changed. Test connection using new ipv4. Nothing.

3) double check port forward and notice the local ip changed(242->245). Why? Check device ip, displays 242. Check server, also shows 242.

3)Check Xfinity settings via browser, also shows reserved ip as 242. Confusion 100. 2 weeks and 3 power cycles later notice port forward changed ip again. WHY?
4)Check MAC address of *server name A*, doesn’t match(never changed device names). Now looking for matching MAC address. Find “generic android device” with matching MAC address(not android).

5) change name to *server name B* and move port forward and reserved ip to that device. 
6) restart server and modem. *server name A* is now missing? 
7)test server with old external ipv4(set manually on server), no work. Test with new Xfinity ipv4, works.

as for getting support, I called Xfinity support and got an automated voice to tell me to call the number on my bill and immediately hung up on me. I called that number at 5pm and an answering machine said “open from 11am to 6pm” and hung up on me(they were open for another hour?!?!) then called the store near me and while I spent 15 minutes telling the phone no to getting the virtual assistant(tried it twice, garbage) i got put in a wait for what it said would be 8 minutes. Found the solution before then..
