I installed the latest update 197 today. After that, my Roadwarrior clients had the issue that no DNS server was assigned via OpenVPN, even though I had specified DNS servers for both DNS 1 and DNS 2 in the client configuration. At the moment it seems as if these entries are completely ignored. Only a single DNS server entered in the advanced server settings is adopted by the client or pushed by the server.
2025-09-23 20:43:11 Options error: --dhcp-option: unknown option type ‘172.16.1.101’ or missing or unknown parameter
The client only receives the entries that are stored in the “Advanced Server Settings” section.
i found this in the ccd client file
#DHCP Optionspush “dhcp-option DNS 172.16.1.100”
#DHCP Options
push “dhcp-option DNS 172.16.1.100”
maybe this is better
Could it be that the DNS 2 field in the WebIF of the OVPN client configuration is not being processed?
In addition, I had to lower the MTU from 1500 to 1470 because my users with Linux OS could connect and ping, but couldn’t use any other services—no SSH, no HTTPS, no RDP. The update hasn’t been well received so far. The web UI in OpenVPN is anything but user-friendly.
Before the update everything worked better, and I was able to leave the MTU unchanged as well.
