was afraid that would happen. Thats in the private forum. Here's copy of it.
Him: Is the router dropping its ARP tables as in are they dynamic as opposed to static this may be why it looses the ports during sleep period ? Other than that if no port trigger is available have you tried putting one in port forward rules and one in DMZ ( I know it will hamper coms to internal lan devices but may work as workaround)
Ive seen plenty of home routers in the past that drop the arp tables due to being dynamic and in my case stops WOL from targeting the correct device internally from external ip my fix was to enable static nat ( ISP may not allow this on the supplied device so bridge mode to device where you can set arp tables to static thus ports should stay mapped through sleep period)

??
The fault in this case to me is the router, dynamic arp tables will cause mapped ports to drop when a device sleeps so setting static ARP should stabilize it unless the UPNP on that device is also set to drop port maps when they sleep ??
Me: Bliss IRL I've tried putting one in dmz and the other port forwarded. One is still strict in that case. All devices are dynamic however the ip's are reserved so they never change ip addresses. I've had the same ip addresses on both since launch day so thats not the issue for me.
Him: O h i see so it was working previous to the last update is that What we are saying ?? ARP tables are not usually accessible via web gui - usually done via ssh or telnet to device and setting the device to hold static records may reslove this as workaround though.
IF it was fine before the latest update then this is a for fix issue for M$.
Other strange things ive seen since day one on XB1 if using wifi encryption say for example WPA PSK 2 - i have seen the XB1 display strict NAT, The only thing i could do in that case to alleviate for my buddy was to disable the encryption fully on the AP and set allow mac assigned access list only ( With broadcast of loads of bogus ssid's for little extra security ) This is not ideal but even with firewall off it would still show strict nat made no bloody sense at all until i pulled down the wifi encryption may imply encapsulation issue possibly i dunno
