Thanks for the reply, I followed the instructions in the handbook for ethernet bridging. In Freebsd 6.1 release you could compile the bridge and tap modules into the kernel, then enable ethernet bridging and actually bridge two interfaces using sysctl.conf. I found that this brought a tap interface up at startup. This did not automatically happen for me using 6.2 release, I have since discovered however that openvpn on startup brings up a tap interface, but of course at this point the sysctl.conf bridging entry had passed. I have since discovered that bridge has been superceded by if_bridge and that I should be able to bridge the two interfaces using rc.conf. I have entered the correct command, but how do know for sure that the two interfaces are bridged? thanks in advance ----- Original Message ----- From: "Lowell Gilbert" <freebsd-questions-local@be-well.ilk.org> To: "Pete Jones" <pete_sw@hotmail.com> Cc: "FreeBSD-questions" <freebsd-questions@freebsd.org> Sent: Wednesday, May 02, 2007 12:56 AM Subject: Re: Bridging with tap > "Pete Jones" <pete_sw@hotmail.com> writes: > >> Does anyone know anything about ethernet bridging to a tap interface >> in Freebsd 6.2.
