Can a dual Nic connect to a DMZ?
One NIC connects to our internal LAN, the other connects to a DMZ via a Cisco ASA5505. When I configure and save properties for either connection I get the following warning messagebox: “Warning – Multiple default gateways are intended to provide redundancy to a single network (such as intranet or the internet).
What happens if you have two NICs on the same subnet?
Configuring two or more NICs on the same subnet may cause communication problems. One of the most common scenarios resulting in multiple NICs being assigned to the same subnet is when both a wired and wireless interface are used to connect to the same network.
How to add secondary NICs to the OS in azure?
Add routes for secondary NICs to the OS by completing the steps in Configure the operating system for multiple NICs.
