If I have 3 different vlans, are there any problems having different firewall rules between each vlan and the WAN link? I saw an earlier post about some issues with filtering between vlan's but this should'n be the same.

Yes, this sounds different than the earlier post.

Firewall rules can be applied for WAN to LAN or vice versa flows.

As vlans are logically associated with LAN, firewall rules should be applicable for WAN to vlan traffic.

Using source or destination IP address in the firewall rules should let one to control which rules to be applied for which vlan traffic.
