Am having trouble with v42 of the firmware. I upgraded my Router and 2x satellites this morning but could not connect to the internet. Have now downgraded back to v41 and all is good again. Am not sure what is going on or how to diagnose things further.

Further to the above message, there is something wrong somewhere with v41 too. v41 will not work on one of my RBR50 Satellites. So far I have rolled the non-working one back to v40. On both v41 and v42 access to the internet is block by the Satellite.

Hi Voxel,
Thank you very much for the hard work you put into this project!
Im on the latest firmware and unfortunately i cant get openvpn server to work. It worked fine in older firmware versions.
I'm on a static IP address from my ISP. I pinged IP from my cell phone and it pings with no issues.
I downloaded fresh cert and connection profiles from opennvpn tab on router.
On my iphone, while connected through cellular, Openvpn client cant reach host with UDP 12973 port. It just times out trying to connect.
I tried to see logthrough netgear interface but cant see anything vpn related there.
Can you please help where to look?
Thank you!
