Dear developers, I found a little issue, hope you don't mind of having a look at it. The ocserv seems to packet the "NAS IP address" which is used by freeradiusclient to send messages. Recently I deployed a cloud VM which is placed behind a firewall to separate the internal network from public Internet. The VM is assigned with a group of private IP addresses (e.g. 10.15.0.0/22), and at the same time with a dedicated public IP address (e.g. 210.*.*.37) or even more, while the firewall need to be set manually to forward. Therefore what we can see from the radius server is just certain private IP address. My concern is whether it is possible to set "NAS IP address" in the config file as "NAS identifier". Due to the consideration of security and probable conflict of private addresses, I suppose a flexible setting would be a better idea. How do you think about it? Regards, Yick
