[Openvpn-users] Is ethernet bridging possible on FreeBSD via OpenVPN?

[Alex K <alex@xxxxxxx>]

I've looked through all the documentation and the majority of it seems 
Linux specific.  I however am using FreeBSD and can't seem to figure 
out how to get ethernet bridging working.

Here's what i've done so far.

- Using OpenVPN 1.4.3 (compiled from source) on both machines (FreeBSD 
4.8)
- Using the if_tap.o module (installed from the ports)
- Compiled BRIDGE support into the kernel, rebooted
- Ran OpenVPN to create the tap0 interface
- Set bridging via sysctl:

net.link.ether.bridge_cfg: fxp0:1,tap0:1
net.link.ether.bridge: 1

Both interfaces are now promiscuous (fxp & tap), but when doing a 
tcpdump on either fxp or tap (can a tcpdump be done on tap?), traffic 
does not seem to be crossing over from the other end of the tunnel.  
What am I doing wrong??

Here's the openvpn.conf i am using:

dev tap
remote 10.32.253.46
secret /usr/local/etc/static.key
port 5000
comp-lzo

I know that 10.32.253 is a private ip, but I'm working with a weird 
network topology and i've ensured both machines can reach each other 
(at least via ping).  They seem to report pinging events on either side 
of the tunnel when they occur on the tunnel so they are seeing each 
other.
