How to configure Bridge mode - Get IP address check error

Pritunl Pritunl VPN
1

Hi,

I wanted to test the bridge mode on one of our servers but I’m not able to activate the configuration.

Server version:
pritunl/unknown,now 1.30.3116.68-0debian1~bullseye amd64 [installed]
Server network
10.100.4.0/23 usable IP addresses: 10.100.4.1 to 10.100.5.254

If I try to set up the bridge like this:
Network Start: 10.100.5.201/23
Network End: 10.100.5.240/23

I get this error:

Same if I put in the values for a extra subnet, wich I this is wrong.
What are the right values to set up the bridge mode?

Greetings

Network start and stop should not contain a CIDR prefix.

Hey thank you for your answer.

I tried this of course, then the gui tells me:

Bridge network start and end must be inside the server network.

And no log entry is done.

Hello,
are there other ways to adjust the settings? I really would like to test the bridge mode.
