Welcome to LQ

Firewall?
Is the ssh daemon running?
Is port 22 forwarded on the router to the local machine?
Does your isp block port 22 incoming?
Can you connect on the local machine
Code:
ssh 127.0.0.1
Kind regards

I wrote about this in a post in my blog
Shamless plug

You need to add a rule like this to the iptables configuration of your server:
Code:
iptables -I INPUT -p tcp -m state --state  RELATED,ESTABLISHED -j ACCEPT

Are you connecting from the outside to the inside, or on the same LAN?

Kind regards
