Hi!
OpenVPN still doesn't work on firmware version 7.20.4 (and 7.21beta11).
I ran some tests and discovered that the problem occurs when I initiate push routes from the OpenVPN server (Linux) to the client, and the OpenVPN client simply freezes during the connection process.
If I disable push routes on the OpenVPN server (Linux), the connection succeeds. Therefore, all routes must be entered manually.
When I check the box:
Don't pull routes, it doesn't affect the freeze.
Only the error appears in the log:
warning - received OVPN option length exceeds limit
Perhaps this will give the developers some insight.
I created a support ticket #[SUP-200620] - 2025/10/03
