No XMPP service will work on our ZyXEL ZyWall USG 50. We primarily use HipChat for communication, so when I try to telnet the server and port, I get an error:
> telnet chat-main.hipchat.com 5222
nodename nor servname provided, or not known
Every instance of Windows, regardless of laptop type, are working perfectly. Also, hardwired and wireless connections have the same results.
- Is there any way to test generic XMPP ports or find out what the issue is exactly?
- For anyone familiar with ZyWall routers, how can I test enabling/port-forwarding XMPP ports very safely?
- How can I tell if the port is actually being blocked?
- What would cause something like a specific port to be blocked only on Mac OS X?
Thanks in advance.
