You'll probably need some other lines to, to make sure cable power is  
provided. In many cases, this is mandatory for reliable communication.

This could be due to the above problem. Try if running the driver in  
debug mode like

     megatec -DDD -a ups

reveals some additional information.

> ACL all
> ACL localhost
> ACL firewall

This will only allow the external interface of the local machine. I  
don't think this is what you intended, since in that case you had  
better used 'localhost' instead. If you want other machines to connect  
to this server, you'll have to relax your netmask.

> ACCEPT localhost
> ACCEPT firewall
> REJECT all
