Ubuntu Servers :: Setting Up Ufw For A Website - Disallow Everything Except Ssh / Email?

[URL] I want to

Code:

sudo ufw default deny

and then

Code:

sudo ufw allow ssh
sudo ufw allow smtp
sudo ufw allow www

[code]....

to allow the services I need, am I missing anything ? I assume allowing ssh will also allow scp ? (heck I will allow sftp as well anyway).However my problem is I am connecting remotely, so the only way I can do what I want is to actually do a

Code:

sudo ufw default allow

then use a list of the services provided by

Code:

less /etc/services

and deny each service individually? This seems a pain as if I turn on the firewall with default deny it will boot me out of my ssh connection?
