So I'd suggest to set up a cross-connect between the interfaces: # ngctl connect eth0: eth1: lower lower If you like to filter: # ngctl mkpeer eth0: bpf lower left # ngctl connect eth0:lower eth1: right lower Then you can apply any filtering using ng_bpf (by throwing away (non)matching traffic to an unconnected hook)
