Hello

Routed access-list (RACL) would be good a good solution

ip access-list extended vlan100
deny ip 192.168.2.0 0.0.0.255
permit ip any any

int vlan 100
ip access-group vlan100 out

ip access-list extended vlan200
deny ip 192.168.1.0 0.0.0.255
permit ip any any

int vlan 200
ip access-group vlan200 out

ip access-list extended vlan300
Permit tcp 192.168.1.0 0.0.0.255 any established
deny ip 192.168.1.0 0.0.0.255
Permit tcp 192.168.3.0 0.0.0.255 any established
deny ip 192.168.3.0 0.0.0.255
deny ip 192.168.2.0 0.0.0.255
permit ip any any

int vlan 300
ip access-group vlan300 out

Note for vlan 300 the Acl is allowing tcp ONLY if you wish UDP also then it will have to be any any ace entry due to the connection-less nature of the protocol
