Currently, I have setup a demo lab for the OnPlus. I have these devices connected up:
- OnPlus connected to a Cisco SMB switch (via the default VLAN 1.
- A WAN Router (with a Prepaid Telstra 4G dongle) connected to the switch for internet connectivity.
- A UC320W and some IP Phones connected to the switch.
The OnPlus and UC320W can connect (outgoing) to the internet via the WAN Router through the Telstra 4G connectivity.
I can login to the OnPlusBeta portal successfully and I am able to see the interconnected devices.
However, the issue is, if I try to connect to say the UC320W via the Web Connection, it fails giving the message on the browser (tried with both IE and Firefox) --> "Internal Failure to Connect: Unable to connect to internal tunnel. Recreate your remote connection and retry."
If I use a Prepaid Optus 3G dongle, it works fine. I have no issues with Web Connection (via the OnPlus Agent) to the other devices like the switch, UC320W, etc.
I am wondering whether this is an issue with the carrier?
Any thoughts here?
