@johnpoz Yup all of that is true.
Additionally the server is on the same hyper-v machine that all the other servers are on. So it's not a real world networking problem at all. All the Vms are on the same 10Gb virtual switch.
The only odd thing about this particular server is that it has a 6TB volume on it.
Also, this was not a problem with another firewall system that also used openvpn.
I switched to pfsense because the ipsec support is somehow better- this was trying to resolve an issue with a customer we need to connect to.
Now I can't get to testing the ipsec link until I resolve this. I've got a $10,000 Checkpoint sitting here which I want to return.
