Hello Walter001 and thank you for your reply.
the reason why I want to connect AP1 Port 2 to AP2 Port 1 is because I dont have an option to put a switch or something else in between.
I will try to give you the layout of my lan cables:
I have my switch next to my router in my office. the switch port is configured as you mentioned (untagged for lan, tagged for vlan2 and vlan3). the cable that is connected to the switch port goes up into the first floor where AP1 is mounted. AP1 is connected on Port 1 with the cable coming from the switch.
Now I have a cable going from the first floor up to the second floor where AP2 is mounted so I want to get the lan which comes from the office to the first floor into AP1 bridged to the second floor to AP2 so I can configure the same vlan2 and vlan 3 for wireless access.
Does this explanation help you understand my idea. I just cant figure out how to do the config for AP2 so I can get it working like AP1 is already nicely working.
