1 edit | Powerline networking and VLAN tags
I have a small network that I operate at a local marina. This network is composed of a router (cisco 871), a desktop, network camera and an access point.
The access point operates on a tagged vlan (VLAN 2) to isolate it from the main network. This is done because VLAN 2 has a captive portal associated with it for the wireless access. Vlan 1 is native.
I need to secure the router and cable modem as people have been tampering with it. Unfortunately, due to the design of the marina, I cannot run any new wires.
I decided to look at Powerline adapters. However I don't know if they would have the ability to pass Tagged VLAN frames.
The Homeplug 1.0 spec indicates that they support VLAN tagging, however I'm pretty sure this is only related to the communication between powerline devices for QoS purposes, and NOT for the transmisison of data over the powerline adapters.
Of course, most residental networking devices don't even list a "compliance" section so I can't look up if it supports 802.1q tagging or not.
Has anybody attempted transmitting tagged vlan frames over a set of powerline adapters?
EDIT: If these devices act as transparent bridges, I don't think I'll have a problem..... my only concern is if whether or nor it will drop a full frame (which is 1522 bytes when vlan tagged... 4 bytes bigger than the 1518 byte ethernet frame limit) |
