Correct! Also thanks to swap m!
I just realized that bridging adds an ethernet header to the frame and then
send it out on the E1. The issue now remains in the fact that I'm planning
to use this configuration for an E1 where I don't have access to the ISP
side. Bridging is not really that transparant as I'd hoped for :-)
