Hi,
I have upgrade my AR300M with 2.26 firmware (after resetting my settings) and I have now a problem with OpenVPN. I can connect to my VPN server and after a minute the connection is dropped. I cannot connect anymore after because the session is still opened on the server and I cannot open a new session. I was not having this problem with 2.25 firmware.
Here are some logs, can you help me ?
