Hi everyone, I'm using linux bridging for a trasparent firewall. There is some kind of external hardware that I can use to bypass my firewall in case of failure? I mean: if I power off my firewall I want to join physically the two network segments without reconnecting any wire (and possibly without touching any button) Thank You Gianluca
Portwell have some 2-port and 4-port bypass cards which will do the job. So do some other manufacturers. -----Original Message----- From: bridge-bounces@lists.linux-foundation.org [mailto:bridge-bounces@lists.linux-foundation.org] On Behalf Of gianluca Sent: Saturday, 10 November 2007 9:24 AM To: bridge@lists.linux-foundation.org Subject: [Bridge] bypass bridge for backup Hi everyone, I'm using linux bridging for a trasparent firewall.

Thank you. in fact this is what i need, but i've a problem: my device is an embedded platform http://www.pcengines.ch/alix2c3.htm so i need something external or a link to a do-it-yourself instructions (i'm able with solder and electronics part) Bye Gianluca Leigh Sharpe escribio':> Portwell have some 2-port and 4-port bypass cards which will do the job. > So do some other manufacturers. > > > -----Original Message----- > From: bridge-bounces@lists.linux-foundation.org > [mailto:bridge-bounces@lists.linux-foundation.org] On Behalf Of gianluca > Sent: Saturday, 10 November 2007 9:24 AM > To: bridge@lists.linux-foundation.org > Subject: [Bridge] bypass bridge for backup > > Hi everyone, > I'm using linux bridging for a trasparent firewall. > There is some kind of external hardware that I can use to bypass > my firewall in case of failure? > I mean: if I power off my firewall I want to join physically the > two network segments without reconnecting any wire (and possibly without > touching any button) > > Thank You > Gianluca > _______________________________________________ > Bridge mailing list > Bridge@lists.linux-foundation.org > https://lists.linux-foundation.org/mailman/listinfo/bridge >
