Hello,
is it possible to chance the IP subnet on OpenVPN

i’ve a running OpenVPN with the Subnet 10.10.35.0/255.255.255.0
all Connections with Fix IP
but now i need more new addresses

Ouestion:
is it possible to change the Subnet to 10.10.35.0/255.255.254.0
without loose any connection

sorry for my bad english

AFAIK no. Changing the configuration will reboot daemon.

Hello,
not reboot ! :wink:
Only restart the daemon, but…

uncorrect computed your Network -
impossible choice = 10.10.35.0/255.255.254.0
correct choice = 10.10.34.0/255.255.254.0

it means the serveraddress changes…

Hi all,

this should be no problem. You can add “Static IP address pools” --> https://wiki.ipfire.org/configuration/services/openvpn/config/static_ip also while running already existing connections. Subnet calculation will be done by the WUI.

Best,

Erik
