Restarting with a new CSR - VLAN and Network questions

RouterOS Beginner Basics

Hi all,

thanks for having such a platform like mikrotik. I’m currently using 2 CRS125 which will be replaced by 1 CSR326 and 1 CSS326 (SFP+)
I’m now going to use one of the “old” CSR125 and place it at another location which is currently handled by a FritzBox.
So I got 2 questions,

  1. Does this setup make sense and would you use it like this?

  2. I’m still struggeling with the creaton of a VLAN and getting a 2 VLAN connecting through the WAN Port
    I just got the defaul VLAN4095 in the CSR125.
    Could you explain how I manage to get the other VLANS using the WAN Port
