Hey guys,
I have a running Site-to-Site Tunnel just for one site with configured Tunnel network 10.0.31.0/30.
The Server and Client instance on both sites is assigned to separate Interfaces.
On the main site there are 3 different OpenVPN server instances with all /24 Tunnel networks which are working very well.
Now I want to change the Tunnel Network of this specific instance from /30 to /24 to be able to connect more sites.
The problem with this is that if I change the Tunnel network on both sites to whatever (<30 Bits), the connection gets established, but no traffic will pass.
Changing the Tunnel network to /30 makes it work again.
I tried the following:
- rebooting both sides after change of Tunnel network --> same problem
- disabling and re-enabling and restart of client/server ovpn-instances --> same problem
- Re-Applying the assigned Interfaces of the OVPN Interfaces (unconfigured) --> same problem
- Cloning of the server/client instances and assign the clones to the Interfaces --> same problem
I would be happy if someone has another hint for me..
Thx
