- Device: Teltonika RUT950 LTE
- Firmware: FW ver.: RUT9XX_R_00.06.07.5
Seems to be a common issue/request but not seen a solution yet.
Have setup a site to site OpenVPN server on the pfsense router with the following settings
- Server Mode: Peer to Peer (Shared Key)
- Protocol: UDP on IPv4 only
- Device Mode: tun
- Interface: WAN
- Port: 1195
- Encription Algorithm: AES-128-CBC (128 bit key, 128 bit block)
- Auth digest Algorithm: SHA256 (256-bit)
- IPv4 Tunnel Network: 10.0.100.0/24
- Ipv4 Remote network: 192.168.0.0/24
- Compression: disabled
- Keepalive
- Gateway creation: Both
I setup the OpenVPN client on the RTU950 with the following settings
- Enabled: Checked
- OpenVPN config from file: disabled
- Tun/Tap: TUN
- Protocol: UDP
- Port: 1195
- LZO: Unchecked
- Remote host IP: <WAN IP of the pfsense router>
- Resolve retry: infinite
- Keep alive 10 60
- Remote network ip: 192.168.100.0
- remote network ip mask: 255.255.255.0
- Authentication: Static Key
- Encription: AES-128-CBC 128
- Local tunnel endpoint IP: 10.0.100.2
- Remote tunnel endpoint IP: 10.0.100.1
- Extra Options: none
- Static pre-shared key: 2048 bit OpenVPN static key file uploaded to RUT950
However this failes to connect. I note that there is no choice for the Auth Digest Algorithim on the RUT950 and the Local and remote tunnel IP have to be individual not a subnet.
The errors on the pfsense OpenVPN seem to be Authentication/decription issues?
