My router is openWRT, and I have the following networks running on eht0

 

-> Lan  192.168.33.0/24

-> VLAN3 192.168.3.0/24

-> VLAN4 192.168.4.0/24 

 

DHCP running on each network.

Reads like your LAN is operating untagged, VLAN3 and VLAN4 are tagged accordingly. This makes up a trunk port, with VLAN1 (default) untagged, and VLAN3 and VLAN4 tagged. Same config on the switch port connecting to the router port (as well as to any other switch) does bring VLAN1, 3, and 4 to that switch.

What works:

If I set a port to be untagged in lets say VLAN4  and set the PVID to 4  , the port is in VLAN4 clients get ip von the VLAN4 DHCP, all is well.

To make up a port a pure access port e.g. for VLAN4, remove any VLAN memberships except of VLAN4, make VLAN4 [U]ntgged, and PVID 4.

What doesnt work: 

Getting any client/port into LAN/Management so that a client would get a 192.168.33.0/24 adress

Of course this works. Similar to the above, remove any VLAN memberships except of VLAN1, make VLAN1 [U]ntgged, and PVID 1.

Can this be archived somehow? or do I have to "just" change my whole network to be fully vlan capable and run every switch port over VLAN1 e.t.c?

To gain a proper segregation of the VLAN1, 3 and 4, all switches in the data path need to be VLAN capable and configured accordingly. A non-managed switch should only be connected to a non-trunk, read an access port for one specific VLAN only, makes it operating as an switch with all access ports for the VLAN the access port it does connect to.
