Invalid Traffic

Question

Within the logs of my XG v17 firewall I'm seeing thousands of entries regarding Invalid Traffic. I have a firewall rule which is set to allow all outbound traffic so this should cover all traffic however it's not. Of these requests there are entries relating to Internal Devices trying to contact XG and Internal Devices trying to contact services on the internet. I have recently noticed that random websites load slower than I'd expect. Below is a screenshot of the logs 
 Is anybody else experiencing this? if so has anyone found a solution to this? 
 Any help I greatly appreciated 
 Thanks

So that rule is an inbound rule, meaning you are allowing all traffic IN to your network. Is this your intention? 
 Remember that the firewall is stateful and does not require an inbound rule. All traffic allowed out (e.g. LAN -> WAN) will automatically allow return traffic in. 
 As per the message "Could not associate packet to any connection," please refer to the following thread with similar issue: Numerous 'Could not associate packet to any connection.' messages in the firewall log
