Yes I did, and it doesn't work. But I'm able to get an address through
dhcp, but other than that nothing goes in or out. I thought the isp's
side did somehow allow my tagged dhcp request and sent an answer back.
But after testing a direct connection, with tagged packets but without
the m0n0wall as bridge between, I wasn't no longer able to get an dhcp
Now I think about this, it all makes sense. The responding side doesn't
know about my tagged packets, so they'll respond untagged. At that
point, m0n0wall couldn't possible know these packets should be tagged
again, at least not when operating at L2 (bridge) level. But I can
imagine there could be some tagging mechanism based on the packet's
(returning) destination, possibly with static routes or something?
Thanks btw for your answer :)
