This is the way you can install a Debian firewall rule in Debian Lenny.

Create your iptables configuration.
Save it to a file:
```
iptables-save > /etc/iptables.up.rules
```
Create a startup file here:
```
vi /etc/network/if-pre-up.d/iptables
```

Insert this to the iptables file you have just created:

#!/bin/bash
/sbin/iptables-restore < /etc/iptables.up.rules

Make the file executable:

chmod +x /etc/network/if-pre-up.d/iptables
