    @Bambos said in HEADS UP: OpenVPN deprecating shared key mode, requires TLS, deprecating cipher selection: for the remote access VPN, if is SSL/TLS + User auth, does this working with freeradius as well ? I'm using FreeRadius myself for the captive portal. Never tried to do this ... You probably want also see this one also : FreeRadius on pfSense software for Two Factor Authentication although I presume that article was written for those who wanted to "why do things the easy way if much harder is so much better ?" @Bambos said in HEADS UP: OpenVPN deprecating shared key mode, requires TLS, deprecating cipher selection: i have many 2.6 versions clients to upgrade Keep in mind that 2.6.0 uses the "old" (now completly ditched because of security) OpenVPN (and now also old OpenSSL !!) libaries. The recent pfSense uses the more modern OpenVPN and OpenSSL. All this means that some options won't work anymore. Some more options will work, but will be depreciated soon (as usual). I Use OpenVPN myself, so I always have a look at the "source" : web pages like this and the classic openvpn support forum. The OpenVPN client also changed to support the newer OpenVPN server. And yes, I agree, syncing the entire openvpn user fleet can be a hassle.

    @timbopoise said in OpenVPN instructions for ubuntu server behind router firewall and no ufw: Or am I missing something? Setting up a VPN behind the router, instead of on it, causes routing issues. Devices on your LAN have to learn somehow what the route to the other end of the VPN is. DHCP won't do it. If the VPN is on the routing, it sorts things out as usual.

    @jucelio_rosa said in Client server with two point-to-point VPNs (SSL/TLS) connection drops.: On the server, we have two links (a "primary" link and a "backup" link). What exactly do you mean with the term "link" here? Where is the OpenVPN server running on? Where is the clinet running on? How does the config look like?

    @elvisimprsntr Thanks for that elvisimprsntr. I don’t use “privacy” vpns for privacy, just for casual defense against geo-blocking and it works for me. Thumbs up for that video though.

    @TheGushi said in OpenVPN with ipv6 delegated prefix: I do not know what prefix my ISP will delegate to me. Hopefully, it won't change. I've had the same prefix for almost 7 years. However, you have to select System /Advanced / Networking Do not allow PD/Address release to keep from getting different prefixes. But not all ISPs obey that.

    @the-other Ok, I made a specific rule in the OpenVPN interface to allow any to both NAS servers. [image: 1761707110778-2cd0716f-d4f0-4e63-94e8-4fc93788fd6d-image.png] Here you can see me connecting to the VPN server with my iPhone and attempting to ping both the NAS servers. The traffic passes through the firewall but the ping fails to the Synology (200.4). [image: 1761707746508-eb97e248-fbd4-43cf-977c-31d87df234ce-image.png] [image: 1761707789724-efcea745-54b9-4460-a44a-e2fffc8c5644-image.png] I can, however, successfully ping the backup NAS (200.5) but I cannot connect to that one either with the File Explorer app. BTW, the backup NAS is an old Asus AC-RT86 router in AP mode with WiFi disabled and a SAMBA SSD in the USB port.

    Posting here because I found this thread when troubleshooting the same error message, so maybe this helps someone else: In my case it was due to an asymmetric routing situation that had developed because of static routes defined within the OpenVPN "remote network" settings. I have a multiple WAN situation with failover gateway and failover VPNs defined through policy routing groups. The behavior I experienced was very similar to what you describe, which in my case was caused by return packets flowing across a different interface than the origin packets. The firewall couldn't see the return packets, and closed the state. I couldn't figure out why traffic was coming in on one interface but going out on another, despite setting up policy routing in the firewall. In my case the "aha" moment came from reading https://docs.netgate.com/pfsense/en/latest/troubleshooting/asymmetric-routing.html -- I removed the non-obvious static route in the OpenVPN settings and instantly resolved multiple issues.

    So, poking around in docs, seems like maybe the weapon of choice here is the framed-pool RADIUS attribute. Look like you can assign distinct IP pools to clients using this attribute. Anyone know if this attribute is compatible with the FreeRADIUS package that is available for PFSense? Can OpenVPN use this attribute for assigning IP addresses to clients? Anyone done this successfully?
