Hello,
I have a problem that I can not solve by my own and I hope someone here can help me.
My setup is looking like this.
As you can on the picture, evertything is almost working like I want it to do.
I want to connect clients directly to my mikrotik and be connected to VLAN 100 and get an ip adress from the DHCP server.
But I cant get it working.
When I connect anything through my cisco, Its get into vlan100 (or vlan845 which I want it to be) and gets an ip adress from the DHCP and are ready to communicate with internet.
Im using RB450 and my setup in the mikrotik i looking like this:
/interface vlan
add interface=br-trunk l2mtu=1516 name=vlan100 vlan-id=100
add interface=br-trunk l2mtu=1516 name=vlan845 vlan-id=845
/interface bridge port
add bridge=br-trunk interface=ether1-gateway
add bridge=br-trunk interface=ether5
/ip address
add address=192.168.88.1/24 interface=vlan100 network=192.168.88.0
/ip dhcp-server
add address-pool=default-dhcp disabled=no interface=vlan100 name=default
/ip dhcp-server network
add address=192.168.88.0/24 comment=“default configuration” dns-server=192.168.88.1 gateway=192.168.88.1
/ip dhcp-client
add comment=“default configuration” dhcp-options=hostname,clientid disabled=no interface=br-trunk
/ip firewall nat
add action=masquerade chain=srcnat out-interface=br-trunk src-address=192.168.88.0/24
I do know that I dont have any config for ether2 and ether3, I tried to set up and br-vlan100 and connect ether2,3 and vlan100 to it, but then my dhcp-server gets invaild
And I changed interface=vlan100 to interface=br-vlan100 but then DHCP only works on the clients I have connected to my mikrotik not any client i connect to my cisco.
So my question is: How can I get VLAN100 working on both places? 
Feel free to ask any questions.
