QinQ and non-stacked (single tagged) packets on a port; zyxel 3700
The device connected on port 3 understand QinQ and can process them OK - if I get them to it, and then it shunts out double-tagged packets - 999 outer and 888 inner (as the input). The output packets need to get back to port 1.
Is it possible to achieve this?
All clues welcome. My background is cisco, so the SPVID and TPID terminology in the manual is somehow just not clicking with me. I am sure you are as confused with my outer and inner terminology. I only visit this switch once every few years, so I am not fluent in zyxel ;-(
