Re: java applet port in ipf
Loading the applet is the first, but often the only step. In some cases,
though, an applet may try to make a new network connection to pull data
from a server.
If you are trying to protect the client, then your ipf rules should allow
the inside to establish connections to the outside. If you are protecting
the server with a firewall, then it should be possible to know which port
the applet will try to reach.
