Hi folks,
I've been trying to create a layer2 VPN using FreeBSD boxes as the gateways.
The 2 methods I thought of are:-
a) Create a tunnel between the 2 gateways using gif interfaces, and
bridge the gifs onto a real NIC.
Both methods seem to work fine, unless I try and put 802.1Q traffic down
the VPN, in which case neither method works.
This should work fine with vlan headers, do you have any indication of
where the problem is? you may need to get packet dumps at the sending
and receiving ends.
Grab a tcpdump at the sending bridge0, sending interface, receiving
interface, receiving bridge0. You can send them to me if you need help
deciphering them.
cheers,
Andrew

Hi Andrew,
I couldn't see why it wouldn't either. It's just an ethernet frame with
an extra field filled in AIUI
I did do dumps earlier, and the problem seemed to be around about the
bridge device at the far end as I pinged, however I will start again
from scratch tomorrow and get some data. I was on a bit of a mission
today as I need to have a working solution soon, so I tried combinations
of OS and tunnel techs. The only actual success I have had so far is
Linux with OpenVPN in tap mode.
Anyway, thanks for your help so far and I shall return.
Cheers,
Dunc
