McAfee firewall log, allow this?

Just looking over the logs on DS's McAfee firewall (after trying several unsuccessful attempts at downloads from Blizzard Entertainment and attempting port forwarding from the router and all that fun stuff!). And all I see there for inbound traffic are UDP attempts from our ISP's DNS server addresses. There is the occasional note as well that a port scan was attempted by sending a large amount of traffic, again from an IP address of our ISP's DNS server. I don't know if McAfee blocked these or not, but the options are there to "add this as trusted" or "add this as standard" or do a traceroute.

Is it OK to add this as trusted for both the DNS server addresses or should things just be left as is?

Re the issue with the Blizzard download, I don't see the port numbers in the log that Blizzard requires. I'm not sure if a firewall is blocking this or not. Canyouseeme.org indicates none of the required ports is being blocked by the router's firewall. I was trying to determine if McAfee's firewall was blocking those ports, which is why I was checking logs, but I can see no indication that this was the case.

Anyway, my question was about whether or not UDP from and ISP's DNS server IP's should be trusted or not.

Thanks.

 

OK, thank you!
