dd-wrt

I set up multiple isolated vlans in dd-wrt. Now I need to forward a port to vlan2.

I isolated the vlans using:

iptables -I FORWARD -i br0 -o vlan2 -j DROP
iptables -I FORWARD -i br0 -o vlan3 -j DROP
iptables -I FORWARD -i br0 -o vlan4 -j DROP

Now I need to block a clients on each vlan from accessing the router.

This doesn't work:

iptables -I INPUT -i br0 -o vlan2 --dport telnet -j REJECT --reject-with tcp-reset

I'm new it iptables... am I missing something?
