iptables & nmap

Dear experts and gurus,

I have a clean debian install with this rules configured:

*filter

# Allows all loopback (lo0) traffic and drop all traffic to 127/8 that doesn't use lo0
-A INPUT -i lo -j ACCEPT
-A INPUT ! -i lo -d 127.0.0.0/8 -j DROP

# Accepts all established inbound connections
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

# Allows all outbound traffic
# You could modify this to only allow certain traffic
-A OUTPUT -j ACCEPT

# Allows HTTP and HTTPS connections from anywhere (the normal ports for websites)
-A INPUT -p tcp --dport 80 -j ACCEPT
-A INPUT -p tcp --dport 443 -j ACCEPT

# Allows SSH connections, use port number as specified in sshd_config file
-A INPUT -p tcp -m state --state NEW --dport 30000 -j ACCEPT

# Now you should read up on iptables rules and consider whether ssh access 
# for everyone is really desired. Most likely you will only allow access from certain IPs

# Allow ping
-A INPUT -p icmp -m icmp --icmp-type 8 -j ACCEPT

# log iptables denied calls (access via 'dmesg' command)
-A INPUT -m limit --limit 5/min -j LOG --log-prefix "iptables denied: " --log-level 7

# Reject all other inbound - default deny unless explicitly allowed policy
-A INPUT -j DROP
-A FORWARD -j DROP

I got it pretty much from here: http://wiki.debian.org/iptables

The idea is to close all ports excluding 80, 443, custom ssh port, and allowing icmp.

I checked the rules after applying it with iptables -L, and everything seems fine.

But when I did an nmap 127.0.0.1, I only see port 111 open.

I didn't even open port 111 according to the iptables rules.

Here's the output of the nmap:

Not shown: 999 closed ports
PORT    STATE SERVICE
111/tcp open  rpcbind

Maybe this is a silly question. But anyone knows what I did wrong?

I did reboot and re-applied the rules on boot-up. Same thing.

Cheers,
