Title. I've my PC and my Steam Link connected to my TD-W9980, both with a Cat6 cable (I got multiple from work). Cable is working I swapped it and tested both old and new. Do I have to put some exception inside my router firewall to better allow these two devices to see each-other?
Do I really need the default firewall rules 'Allow-IPSec-ESP', 'Allow-ISAKMP'? And 'Allow-DHCP-Renew' (this one is necessary to get IP from ISP right?) ?
