Hi, You can find the patch here http://people.freebsd.org/~thompsa/if_bridge-5stable.diff 1) Apply the patch # cd /usr; patch -p0 < if_bridge-5stable.diff 2) Add 'device if_bridge' to your kernel config (or use the module) 3) Do the "buildworld, buildkernel, installkernel, installworld"-dance Feel free to test and report any problems. configuration is the same as in current, see if_bridge(4) for details. cheers, Andrew
