|
Hi!
I want to do a project. I want to be able do some machine learning based filtering of some of the Ethernet frames in the switch.
To do that first I need to be able to read the data on the wire for the learning phase, that is not a problem. The second is to be able to filter some of the packets from within the switch. That seems to be a technical problem.
I've been looking into DD-WRT (I have a TP-Link 741), but I don't find the part which deals with the Ethernet switching where I could hook my code up and make some decisions regarding to which packet to let through and which not.
Do you have an idea?
Thx! |

In general the router you have is very basic and some of the DD-WRT valuable features might not work at all...
First get a better router with at least or more than 8MB flash size RAM....http://www.dd-wrt.com/wiki/index.php/Supported_Devices
Second DD-WRT supports "switch mode" but only a basic switch mode, non-managed mode.......

Third if you need to set up a policy based routing look here:

or VLAN tagging (you'd need another router)
http://www.dd-wrt.com/wiki/index.php/VLAN_Support
as well you can filter packets using IPtables as long as they are not stripped that bad (depends on router and dd-wrt build you are running)...do keep in mind some builds have stripped commands and variables in order to fit in a smaller flash size RAM builds for a cheaper routers, so better router, better build, more router capabilities, and better performance... .. _________________ Atheros
