Hello Damion, > There's some bridge howtos, and stuff in the kernel doco: > http://www.tldp.org/HOWTO/HOWTO-INDEX/networking.html#NETBRIDGE > linux/Documentation/networking/bridge.txt The problem is, that bridge-utils don't work with a gre tunnel: router:~ # brctl addbr br0 router:~ # brctl addif br0 eth1 router:~ # brctl addif br0 gre0 br_add_interface: Invalid argument Is there any possibility to make bridge-utils work with a gre-tunnel? Or are there any other bridging-methods? Thanks in advance! With best regards Martin Klewitz
