The client connects to vpnhost01 and is assigned 10.10.20.130/25. Here’s the rundown now (I’m just using the Admin VLAN with a replicated server to simplify things): I can’t seem to get the “any host can be the next-hop” working with my setup. Regarding the NAT vs non-NAT, that seems to indicate that outside of AWS or Oracle Cloud, the only way to have a truly redundant setup that allows for a single host failure is to use NAT, since non-NAT requires the static route to a single machine that could be down.Ī follow-up to the static route config for a non-NAT setup with multiple hosts. However, how do I specify that the “dev” VPN server only runs on the “dev” availability group hosts, or is that not how I use this feature? The docs might indicate I do not have ultimate control over which host the VPN server uses in a cluster. I then set the Availability Group for each host to either “admin” or “dev”. Ultimately, it looks like I’ll have to set up the servers in a way that they only run on a host that only uses the VLAN that corresponds to that VPN server (so for two VLANs, I’d need two hosts that are just on VLAN 20 and two that are just on VLAN 40). Since I have to attach an interface for each VLAN to the host, and Pritunl doesn’t have a way to route a specific VPN server over a specific gateway that corresponds to its VLAN, everything goes out the default gateway. So after thinking about this a little more, and taking the information you provided into account, it sounds like it’s not possible to run a Pritunl host machine that has multiple VPN servers that span VLANs. If someone connects to vpnhost01, the static route for the VPN subnet in the firewall needs to point to vpnhost01 (10.10.20.5), but then it won’t work for vpnhost02. Obviously I could get crazy with firewall rules on the VPN host, but that seems messy.Īlso, if I have a dual VPN host set up like this that runs replicated servers, can I not use NAT on the routes? Since non-NAT traffic requires a static route on the firewall to push the VPN subnet back to the correct VPN host, I can only make it go to one specific host. Is the only way to handle this to only route the specific subnets that each VPN server should access? Hopefully that’s not the case, since the Dev VLAN will need access to some parts of some VLANs, but not the entire subnet. However, that ends up giving the Dev VPN connections access to the production VLANs because the traffic can traverse the VPN through the VPN host and through its default gateway (which on vpnhost01 is on the Admin VLAN).įor example: A Dev VPN client tries to access 10.0.10.50 (VLAN 10, should be blocked)Ĭlient → Dev VPN → vpnhost01 → default gateway (10.10.20.1) → 10.0.10.50 (allowed because VLAN 20 is trusted). In order to allow each VPN server to run on each host, it seems like I need to assign an interface to each host from each VPN VLAN (20 and 40) so the VPN subnets are routable to the rest of the network. For simplicity, each VPN server routes all VLAN subnets over the connection (since they have to be restarted if there are changes), and the switches and firewall handle the access to the other VLANs. The Dev VLAN only has access to the Dev VLANs. The Admin VLAN has access to all other VLANs. The host themselves are currently running within VLAN 20 and 40 for Admin and Dev (respectively) and assigned an IP on that subnet. We then have two host machines running Pritunl, and we would like both VPN servers to be accessible on both hosts for resiliency and balancing. This is the simplified version of our config (we have an Enterprise license): It also helps managers regulate security policies by authenticating access through single sign-on, mobile push, 2FA, and more.So I’m trying to set up a Pritunl cluster in our new environment that has VLAN segments for production and dev, and I’m having trouble figuring out how to set everything up to work. Pritunl lets businesses utilize user auditing functionality to prevent phishing attacks and detect intrusion. The software also provides an automated Virtual Extensible LAN management module to maintain client communications by replicating servers across various availability zones. The platform offers VPN auto failover functionality, which lets professionals automatically connect with the backup VPN server to ensure seamless connectivity. Teams can configure single sign-on across YubiKey, Okta, OneLogin, Google Workspace, Auth0, Duo Security, Azure Active Directory, and Slack to securely login into Pritunl. The solution integrates with Amazon Web Services API, which enables teams to configure VPC and automate IP routing table management. Pritunl is an enterprise VPN software that helps businesses of all sizes create cloud virtual private networks across various datacenters and share the access with remote users.
