Steam Network Unreachable with Untangle 10

I have recently upgraded my Untangle version from 9.4 to 10 and now 10.1. I have been an avid user of Untangle since 2005 and have never had an issue with it that I couldn't figure out. However, since upgrading to 10.0 and now 10.1, none of my clients on my network can access Steam networks. I know for sure that is is my Untangle firewall as I have completely removed Untangle out of my network path and I can connect to the Steam network just fine. I am receiving the following error message at the client when trying to connect:

I have disabled Web Filter, Virus Blocker, Phish Blocker, Application Control Lite, Intrusion Prevention and even my Firewall module with no avail. I have also added bypass rules to allow the appropriate TCP and UDP ports from potentially getting blocked by anything (see below):

I also removed any filter rules to try to ensure that maybe that could be the cause. I also added a filter rule (including a rule in my firewall) to allow ALL egress (outbound) traffic out of my network with also no success:

Also tried an input filter rule as well (removed the block all also to test with):

Unfortunately I can't see any logs within the untangle that is showing me that this traffic is being blocked as it leaves my network. If there is anyone who has had a similar issue, your help would be much appreciated. I am impressed with the new version of Untangle and am really trying to avoid to roll-back to version 9, however at this point I have no other alternatives.
