We have only one vlan for the entire dslreports.com system message WHAT IS VLAN HOPPING? VLAN hopping (virtual local area network hopping) is a method of attacking a network by sending packets to a port that is not normally accessible from a given end system. (A VLAN is a local area network with a definition that maps devices on some other basis than geographic I assume that vlan hopping would be part of those tests as I believe it's trivial for any packet smith to make one. I think all you have to do is double tag the packet, as vlans have no authentication. this software isn't for high end hackers it a collection of buttons that says try this! I'll never offer guest WiFi or guest lan it's to vulnerable. So what would be a good wifi extender for around $100 or under (Canadian price) that will run a 4K smart tv and also reach all the way to the top level for my kids TVs and computers. Any help to point me in the right direction would be greatly appreciated. VLAN Hopping is an attack where the attacker is able to send traffic from one VLAN into another.
