Problem connecting to Siemens CMR2020 module via OpenVPN

Post by ajfdezg » Sun Aug 30, 2020 9:31 am

Hi,

I am not able to establish a VPN connection between my Siemens CMR2020 module (server) and my Win 10 PC (client) with OpenVPN GUI. I was hoping someone here can help me find and solve the problem.

Here is the Siemens CMR2020 module manual -> https://cache.industry.siemens.com/dl/f ... 040_78.pdf

And here, the Siemens application guide that I have followed -> https://cache.industry.siemens.com/dl/f ... V10_en.pdf

These are the client config file, and the OpenVPN GUI log ->

Client config

dev tun0
disable-occ
remote 10.169.185.113 1194
ifconfig 10.8.0.1 10.8.0.2
nobind
keepalive 15 60
route 192.168.1.0 255.255.255.0
tun-mtu 1500
fragment 1371
mssfix 1282
persist-key
replay-window 512 15
cipher AES-128-CBC
auth SHA256
auth-nocache
comp-lzo
verb 4
key-direction 1
<secret>
#
# 2048 bit OpenVPN static key
#
-----BEGIN OpenVPN Static key V1-----
I removed the key here
-----END OpenVPN Static key V1-----
</secret>


OpenVPN GUI log:

You need to check your server log.

Hello TinCanTech,

Thanks for your reply. I cannot check the server log because it is embedded in a Siemens CMR2020 module. This is not a conventional PC but a PLC module that comes with an integrated OpenVPN server. A diagnostic report is the closest I can get to a server log. According to it, everything seems to work fine on the server: https://drive.google.com/file/d/1OItW4B ... sp=sharing.

Any other ideas?

Thanks

I expect your device can still output a log file to an external syslog host.
