Re: [PLUG] Find Open Ports
|
wait - i'm confused.
you're still going to be running your webserver from within your home
network, right? if so, what you need to figure out is what outgoing
ports your employer is blocking or not blocking, no?
(and if 80 outgoing is open, can't you configure your home network to
listen on port 80?)
