VLAN Issue

You’re mixing apples with oranges and your VLAN config is a complete mess. You either use VLANs all the way or don’t use them at all, hybrid setups don’t work as expected.

  1. Remove or change pvid of vlan bridge to 20 and remove frame-types if you don’t want to lock yourself out:

add comment=VLANTEST frame-types=admit-only-vlan-tagged name=bridge_vlan
pvid=200 vlan-filtering=yes

to:

add comment=VLANTEST name=bridge_vlan
vlan-filtering=yes

  1. Create a VLAN for the 192.168.88.0 network and change all of the settings associated with it:

/interface vlan
add interface=bridge_vlan name=LAN_VLAN vlan-id=30

/ip address
add address=192.168.88.1/22 comment=defconf interface=LAN_VLAN network=
192.168.88.0

/ip dhcp-server
add address-pool=dhcp_pool_Network interface=LAN_VLAN name=dhcp1

  1. Remove ether3 and ether5 from default bridge and assign them as well as ether2 and ether4 to the vlan bridge. Also add appropriate pvids:

/interface bridge port
add bridge=bridge comment=defconf interface=ether3
add bridge=bridge comment=“Standard Output” frame-types=
admit-only-vlan-tagged interface=ether5

to:

/interface bridge port
add bridge=bridge_vlan interface=ether2 ingress-filtering=yes frame-types=admit-only-untagged-and-priority-tagged pvid=200
add bridge=bridge_vlan comment=defconf interface=ether3 ingress-filtering=yes frame-types=admit-only-untagged-and-priority-tagged pvid=30
add bridge=bridge_vlan interface=ether4 ingress-filtering=yes frame-types=admit-only-untagged-and-priority-tagged pvid=30
add bridge=bridge_vlan comment=“Standard Output” ingress-filtering=
yes frame-types=
admit-only-vlan-tagged interface=ether5

  1. Remove use-service-tag=yes on VLAN Verwaltung interface because it is associated with a different ethertype (0x88a8), assign it to the vlan bridge and remove vlan_200_out interface:

/interface vlan
add comment=“VLAN Verwaltung” interface=ether5 name=vlan20 use-service-tag=
yes vlan-id=20
add interface=ether5 name=vlan_200_out vlan-id=200

to:

/interface vlan
add comment=“VLAN Verwaltung” interface=bridge_vlan name=vlan20 vlan-id=20

  1. Clear your whole Bridge VLAN table and add following entries:

/interface bridge vlan
add bridge=bridge_vlan tagged=bridge_vlan,ether5 vlan-ids=20
add bridge=bridge_vlan tagged=bridge_vlan,ether5 vlan-ids=30
add bridge=bridge_vlan tagged=bridge_vlan,ether5 vlan-ids=200

With these settings you’ll achieve the following:

  1. Transparently forward VLAN200
  2. Have a management VLAN20 and a VLAN30 for LAN because, as I said, VLAN aware and VLAN non-aware bridges don’t mix well

If you wish, you can make ether4 an untagged port for the VLAN20 to have untagged access to the management VLAN:

/interface bridge port
set [find interface=ether4] pvid=20

Thank you for all your comments. There was an additional issue with the internet router. Meanwhile I solved the issue without using 2 VLAN. I only use one and the connection between the internet Router and the DECT station is running via a separate WLAN connection.

Best regards
