AirVPN blocked by firewall

[Seedy 0]

I am spending some time at a health care astablishment as staff. When I connected to their WiFi last night I found I was unable to view any catchup TV service due to a firewall block they had put in place. I then tried to run AirVPN which returned the same result so have now, from a different location, added the Netherlands frontend IP address to my hosts file, as discussed in another thread, to try and gain access tomorrow.

If I should still experience an issue, can you suggest any other ways I can hopefully cirumvent the firewall block please, since I think I'm correct in saying that AirVPN has only two frontend IP addresses?

Thank you in advance.
