A solution which works across several operation systems might be openvpn
(http://www.openvpn.net)
Openvpn creates tap/tun interfaces which have ethernet addresses and
support bridging. Its track record security wise has been pretty good
afaik. And its implementation crypto wise is ok (from heresay though,
not an expert here).

Is it possible? brconfig man pages says:
The bridge has support for 802.1D Spanning Tree Protocol (STP), which can
be used to detect and remove loops in a network topology. Using
the stp
or -stp commands to brconfig, STP can be enabled or disabled on each
port. STP will not work on gif(4) members because they lack a
hardware
MAC address.
So I assume that it isn't, but in case anybody knows any workable
solution over OpenBSD I would like to know. I would prefer this
solution instead of having to fight with Cisco gear and L2TP which
seems much more complex (and expensive!).
I need a bridge over the internet in case the long fiber link between
our main and secondary datacenter fails (bandwidth difference is huge,
but it would suffice for our critical apps). STP is necessary for
obvius reasons.
Thanks in advance,
