  @viragomann Thanks for the further response. The 4G Router used at the Client site is either a TL-MR6400 or an Archer MR400. Those routers only have only one LAN port which is connected to an internal 4-port Ethernet Switch. Unfortunately, given that scenario, I can't see a way to connect the VPN Client machine on to a separate subnet at the router. Given the number of potential Client sites the cost is significant so changing the router is not really an option.

  OpenVPN has no user licenses. If it doesn't work, it's almost certainly in your configuration. Typically issues with multiple clients end up being a problem with the certificates/credentials being used (everyone needs unique certs and usernames), or the tunnel network (it should be x.x.x.0/24), or possibly incorrect firewall rules. Post more detail about your configuration and we might be able to help narrow it down. Also check the OpenVPN log for errors, and check the clients to see what addresses they claim to be using at the time.

  Thanks alot for all of the answers. I'll try out the portforwarding thing, aswell as tls-crypt and stunnel. @rico said in How to use VIP's for OpenVPN: Well you don't have unlimited VIPs to cycle them over and over again right? No, but in the past the banned ip's have been unbanned after a month or so. Best Regards Esben

  @peter808 said in unsupported certificate purpose: When did that change? Although I usually try to read the changelogs completely, I do not remember having read about that. That would be a change in OpenVPN itself, not pfSense. Most likely when that changed to OpenVPN 2.4 (which by coincidence was new in pfSense 2.4.0 and later)

  Note from the pfSense Book: Not all clients support tap mode, using tun is more stable and more widely supported. Specifically, clients such as those found on Android and iOS only support tun mode in the Apps most people can use. Some Android and iOS OpenVPN apps that require rooting or jailbreaking a device do support tap, but the consequences of doing so can be a bit too high for most users. Can you see any activity in your Firewall Logs when trying to access the pfSense via WebIF or SSH? I would follow the guide again and try exactly as described with a very basic setup: https://www.netgate.com/docs/pfsense/book/openvpn/bridged-openvpn-connections.html e.g. don't push any routes, don't use redirect gateway and so on, just basic. Disable the Rule in your OpenVPN tab to make your Interface Rule active (which should not make any difference for this problem tho). -Rico

  under the OpenVPN Server configuration section, the pfSense GUI allows you to specify a "DNS default domain name" value to be used by the OpenVPN clients, so that they will resolve hostnames appending that domain name as a primary DNS suffix. On the GUI you can specify additional DNS domain names as well. The "DNS default domain name" field on the GUI translates to the DHCP option 15 and will appear under ISC dhcpd's config as "option domain-name", and the remaining DNS domain names specified on the GUI translate to the DHCP option 119 and will appear under ISC dhcpd's config as "option domain-search". The DHCP client of MS Windows (at least up to Windows 7, included) do not implement the DHCP option 119, so they'll ignore any DNS domain name specified on the pfSense GUI other than the one specified on the "DNS default domain name" field. It's a limitation of the Windows DHCP client. That OS itself has no such limitation, because you can specify multiple DNS search suffixes on Windows clients joined to an AD using GPO's. Take a look at this link, https://blogs.msmvps.com/acefekay/2011/02/12/configuring-dns-search-suffixes/ Regards

  @gareigle said in OpenVPN Client can not traverse site 2 site vpn: I'v tried different fw rules, and the redirect options on the vpn and no changes. I don't think it's a rules issue. I'd say routing. Since this is site to site, the firewall has to route the traffic from it's local network to the other end. Devices connected to the network should have a default route pointing to the pfSense router/firewall. Each pfSense router needs to know a route to the local network at the other end. Do you have that configured. Please note, I've only configured pfSense for a "road warrier" mode, where it runs on a computer to connect back to my home network, not site to site, so I can't advise based on my config.

  I found the issue, it turns out that the OpenVPN server didn't know where to reply to the LAN traffic coming in so I had to add the LAN's route to the OpenVPN server.

  Huh?? What? Your wan will be connnected to isp router... Your lan will be connected to your lan side switches.. pfsense is now the new gateway for all your lan devices. Yeah your tunnel network can not overlap with your lan networks on either site.

  Yes TLS is configured. I disabled it and created a new profile, and the issue replicates. But here is something I am still having trouble figuring it out. There is only one local account in the pFsense. In my team, I am the only one able to authenticate and ping/or connect to internal resources. Everyone else can only authenticate, but can't ping anything or access any internal resources. We all are using LDAP authentication.

  Sorry for the delayed response, I've been away. We have a LAN behind a Netgate SG-1000. We access this LAN remotely via OpenVPN which has been set up using the OpenVPN wizard. I believe this is a pretty simple, straight forward implementation. The OpenVPN interface has no restrictions placed on it, there are no firewall rules other than the default open to all. The LAN interface has the following firewall rules: IPv4 Default allow LAN to any rule IPv6 Default allow LAN to any rule allow Ping I am required by PCI to restrict the LAN access to only select IP addresses. As soon as I disable IPv4 allow LAN to any, I am unable to ssh into the LAN via OpenVPN. I can ping the LAN IP, and if I am already connected I do not lose my connection. Any guidance is appreciated.

  In this case, there will never be any dynamic clients. All of the clients will be cloud servers/sites that require a static IP. I just wanted to cover all bases in case there is a situation in the future that would require dynamic clients on this particular OpenVPN server instance.

  By poking around in the ISP modem/router's settings, I found one that allowed me to do Mac address passthrough - I copy-pasted my pfSense WAN interface's Mac, and Poof, all was well! I suppose I could have done a port forward for the specific port only, but given that my traffic only goes direct to the pfSense box (which acts as my firewall), I think this is acceptable - thoughts?

  Hi, Actually I got it figured out, it was compression problem! Maybe here was too many things wrong and change of things, for one I used now different VPN service as earlier. For second there might have been something wrong in the rules as I when my public ip was in use on the host which should have not been. Dunno, but now it is working as intended. Connection is off when tunnel is down. Correct compression setting in the vpn config started the packet flow. So ***Solved
