I'm trying to help a user who wants to access files on his linkstation from where he works. Problem is that the corporate-firewall blocks port 9000, so he can only use ports that are usually not blocked by firewalls.
He should talk to his IT department and ask them to setup access through their firewall.He should not be trying to circumvent the corporate firewall
without asking for their advice. Where I work, if someone was found doing this without permission they would be subject to disciplinary action and possibly lose their job.
