I presume that the Firewall is what's "not allowing the connection"? If so, the McAfee default rules have most of what's needed (like allowing in/out RDP sessions). I believe the only ones I added for SCCM were:
inbound to local TCP 2701
outbound to remote TCP 2701
If that doesn't do it for you, let me know, and I'll double check it again.
Thanks for the response johnmoe!!
The option to edit the default mcafee firewall policy is grayed out.
Is there somewhere else I'm supposed to be adding this remote assistance rule?
If you're using the "McAfee Default" firewall rule policy, then you'll need to duplicate that before you can make changes. You can't make changes to the "McAfee Default" rules.
Once you've duplicated the rule, you can make the changes you'd like, then assign that policy to the clients.
