IPTables

I am having trouble with iptables and was wondering if anyone can see a 
problem in my rules. I have a slackware linux box at my job and it has a 
direct connection to the outside world with no protection what so ever. 
What I wanted was to just allow http and ssh connections from the 
outside world and leave all connections from the inside network alone. 
My problem is that I cannot access the outside world when i enable these 
rules. Also I cannot ssh into the machine (i dont remember if I started 
the ssh daemon so this could be my fault), I can access my http server 
from the outside though. My rules are below

iptables -F INPUT
iptables -A INPUT -i lo -j ACCEPT
iptables -A INPUT -m multiport -p tcp --dport www,ssh -j ACCEPT
iptables -A INPUT -j LOG -m limit
iptables -A INPUT -j REJECT

Also where are the logs going to be created from iptables?

Thanks,
-Frank
