Hi Andre,

On your comment "unfortunately there is no bridge mode or any comparable
mode available", sometimes the carrier (if it's a carrier supplied DSL
router) will have these settings hidden from standard user's eyes.

You may need to call your ISP and request them to place your DSL router
into "bridged" mode.
