Hi I’ve done a total conf **reset** e firmware **upgrade**. Now: 1. I’ve about **20** GL-AR750S-EXT in production with **3.025** firmware. The only (initial) problem I have is that, for exclude “normal” traffic from VPN, a [patch](https://forum.gl-inet.com/t/openvpn-configuration-to-avoid-the-default-redirection-all-through-the-vpn/6519/6) is required. But all works FINE: I **regularly** access to all client node and to SSH server services (VPN routed subnets). (scenario “ **1** ” of attached file) 2. On one of this router I’ve updated firmware to **3.212** and OpenVPN _don’t works_ for version incompatibiliry with server (scenario “ **2** ” of attached file) 3. Adding “_data-ciphers BF-CBC_” parameter to **ovpn conf** , OpenVPN **connects** to server … but (by default) all traffic is through VPN (scenario “ **3** ” of attached file) 4. Initially all works fine … but after some seconds I cannot access to nodes and to server services. 5. Only restarting router or restarting firewall (from OpenWrt Luci interface) all come to work for some time … 6. Use of patch is another topic … I hope to avoid it using VPN Policies … In summary: On this firmware version it seems OpenVPN is unstable … Detailed Server and client **conf** : [GL.inet configurations.txt.zip](https://forum.gl-inet.com/uploads/short-url/4tJpAAt6Wo2RdjovBCwT4nlUa6q.zip) (1.6 KB) Thanks --- _[View the full topic](https://forum.gl-inet.com/t/gl-ar750s-ext-and-openvpn-on-3-212-version/22285)._
