Linux Iptables

[RF]

How could I block everything but 1.2.3.4 on port 3389 with iptables?

I am running dd-wrt on my router (linux based), and need to allow one ip, 1.2.3.4 (example). Everything else needs to be blocked on port 3389. This will restrict only my own ip address access to remote desktop connections.

Thanks

Hope you are a chick : D
Try this: (hope you are talking about incoming traffic)

iptables -A INPUT -p tcp -s 0/0 -d THE_ROUTER_IP --dport 3389 -j DROP
iptables -I INPUT -p tcp -s 1.2.3.4 -d THE_ROUTER_IP --dport 3389 -j ACCEPT
iptables -A INPUT -p udp -s 0/0 -d THE_ROUTER_IP --dport 3389 -j DROP
iptables -I INPUT -p udp -s 1.2.3.4 -d THE_ROUTER_IP --dport 3389 -j ACCEPT

that must be the job. THE_ROUTER_IP i think its pretty obvious, refers to the ip it is configured for the router : )
