Hi all,

Newish user to OPNSense here.
It has been working brilliantly for me up until recently. I have been having all sorts of freezing on my IPTV box. I have GB internet and other streaming services are working perfectly. Recently I have been watching the live logs to see if I can find out what has been going on to try to troubleshoot this and have managed to narrow it down.
There seems to be a block on the LAN interface for some reason, I do not understand why as it says the source is my mag box on 192.168.1.100. I thought traffic should be allow to pass from the LAN interface to its destination. It seems to be getting caught by the default deny/state violation rule. Whenever I see this stream of red entries, I get a freeze and a black screen on my TV just after. Tracing these IPs seems to link to Google servers. I know these boxes are Android and seem to use time.google.com for their sync but there is a direct correlation here.
Once the new LAN rule is applied, it all works well, and I see the log showing green now for the traffic 'TV allow' rule and no freezing. Then after a short while, it seems to have some traffic again being blocked by the default deny / state violation rule - and then, you guessed it, it would freeze up again!
Please help!! I really have no idea why the new rule seems to be working and (from the same source) then getting caught by the default deny floating rule again....
Well it seems like I had no relies to help me, here.
Managed to figure it out on my own after quite a bit of headache and some chance, I thought I'd share here.
As stated, the box is on .100. Some traffic originating from this address passes, some other does not !!
I was lying in bed using my tablet that night and it started to lose its internet connection. I had a look around and noticed the ip for the tablet was the same as for the iptv box. Which I thought shouldn't happen as there is a reservation set for it.
Digging around on here I found:

It seems OPNsense has an issue with a static reservation inside the DHCP pool range.
So I lowered my ending DHCP range to finish at .99 and rebooted the IPTV box.
BOOM, no more issues
.......
A headache but now working!
