I need a Server 2016 Tech Preview 5 that is a VM in Azure to connect to a VPN using PPTP to access an internal website and a file share. Azure does not support GRE so we need to figure out a way around this and changing the current PPTP protocol isn't an option. Maybe we can have the 2016 Server connect to something else that has GRE before it connects to the VPN server and then have that connect using GRE. Please don't apply if you don't have a solution.

Need someone to provide me tutorials (screenshots and texts) on how to setup VPN with the following routers & platforms (some of them or all): 1- Asus (OpenVPN) 2- Linksys (OpenVPN) 3- Mikrotik (L2TP, OpenVPN) 4- DD-WRT (L2TP, OpenVPN) 5- Tomato (PPTP, L2TP, OpenVPN) 6- Sabai (PPTP, L2TP, OpenVPN) 7- Netgear (PPTP, L2TP, OpenVPN) Important: We are VPN provider and have our own server configuration. You can't copy these tutorials from other websites because it will not work with our configuration. It means if you want to provide tutorials on each model, you should have that model. We will give you a VPN account to test from your-side.

Do you eat, sleep and breathe ZFS? Does properly configuring and implimenting 100's of TB's of FreeNAS storage keep you up at night? Can you create an efficient, simple and reliable storage system like nobody's business? If you love pushing the limits of IOPS, storage capacity, network speed, efficiency and more, this is the position for you. ARCHITECTURE We currently have 3 VMware ESXi servers running primarily Windows Server 2012 VMs. We have a freeNAS box filled with SSDs acting as our VM shared storage, another freeNAS box for our business storage (about 50 TB of space), and a third freeNAS box that is our backup target and archive server with about 100 TB usable of space. All ESXi servers are connected to 10 gbit Netgear ethernet switches (M7100s & M7300s) in a stack with clients connecting to client switches (Netgear M5300's in a stack). The M7300's handle our vlan routing. We have a VLAN for servers (management), Workstations, Phones, and Cameras. We currently have about 40 workstations in Detroit that are a mixture of Windows and Mac. We have a Windows Server 2012 r2 VM that is connected to our business storage via iSCSI connection to serve our files to our users. Our internet is a 1/1 gbps dedicated fiber connection. CHALLENGE - Things are running extremely slow to do any type of file operations, even from the server itself - We are seeing tons of reads/writes and are not sure why - FreeNAS hasn't been updated in a long time - The architecture of the storage might not be as efficient as it could be - It takes forever to do simple copy/paste operations between our main server and the archive server - Backups aren't even maxing out our 1 gbps fiber connection - NTFS permissions are probably not setup properly REQUIREMENTS - Must have expert-level knowledge in FreeNAS, networking and routing and iSCSI - Must be an expert with Microsoft Windows OS, Microsoft Server 2008 + 2012, VMWare - Must have a solid understanding of file systems and how they function - Experience working with pfSense a plus SUMMARY We're looking for an expert in freeNAS, iSCSI, VMware and Windows/Mac to basically get our systems running the right way so our data is secure, protected, available, and to treat the environment as their own. PLEASE NOTE: To make sure that you have read our requirements, please tell us your favorite color and provide examples of how you've architected vm storage (HA), normal business storage, archive storage and backups (on-site and off-site). Otherwise, we will reject all generic applications. If we find the right person and things get fixed fast, there is certainly opportunity for tons of on-going work with everything related to our network environment. ABOUT US Join the Revolution.
