I have a strange problem.. I have a UC520 that is at a hosting facility. I have couple remote users at remote sites connected via VPN using phones behind SR routers.. everything works ok.
My issue is this - I have a small laptop connected to the ethernet port of the UC520 and as soon as I unplug this, phones do not come up. When I VPN to the UC520 from the outside, I can only ping 10.1.10.1 and not 10.1.1.1 or 192.168.10.1.. seems like the vlans are not up when nothing is physically plugged into the ethernet ports. When I plug the laptop back in, system is up and running again...
1. Has anyone noticed this?
2. Is this by design?
3. If so, is there a workaround?
4. If no workaround, can I plug another device.. such as a phone and will it leave the vlans accessible?
Any help will be appreciated! thanks.
