We have an Sonicwall NSA with some VMs running on Hyper-V in 2 x LANs connected to it.
The VMs in the 1st LAN are fine however the VMs in the second LAN keep losing their WAN connection and therefore we cannot access them remotely (we can access them from the LAN).
To fix the issue we just log into the console of the VM and ping the gateway or open IE and browse a website.
This then fixes the issue but only for a few hours until it happens again.
Any ideas? (nothing else is using the same IPs)
