Solve : IPtables accept from X IP's Drop of anything else.?

Answer»

I'm running into some issues with iptables. I cannot see why.

basically I'm using iptables -A INPUT -s X.X.X.X -j ACCEPT to only accept PACKETS from X ip. ( about 20 entries )
When I have put in the IP's I need. I put
iptables -A INPUT -j DROP
iptables -A OUTPUT -j DROP

But
iptables -A OUTPUT -j DROP Kills my SSH connection and then I can no longer connect. I have to flush iptables via rescue mode.

What Am I doing WRONG?Found what I was doing wrong.
iptables -A OUTPUT -j DROP would break my connection because I didn't ADD a rule to iptables to accept outbound traffic from my ip
I don't know.
Can you be specific as to what Unix or Linux you have? And what tools are you using. Is this on a LAN or are you WORKING with IPs from the Internet. If Internet, in what region are you located?

Does this relate to lyu work?
