  • What firewalls does Covad Support? Most firewalls work with our service. We don’t specifically certify firewalls. Why do we need 2 NetGear vs. 1 Cisco? Because NetGear does not support VLAN Tagging. PCs cannot be plugged in behind phones in this example where the ES does not support VLAN tagging.
  • Firewall plugged into port 1 of the router; allowing data to have firewall.
