Encrypting data on a transparent bridge

[yosi david]

I have two sites that I link by Transparent Bridge How can I encrypt the traffic?

L2TP Reduces performance significantly (So I do not use it)

Thanks

Cannot be done, must use routing and ipsec.

Hello Yosi,

as Paolo has noted unless you use L2TPv3 and you put the L2TPv3 session inside an IPSec tunnel you cannot get encryption.

By definition a transparent bridge cannot modify the frames it moves.

Hope to help
