- For IKEv2 mode, add a new variable VPN_CLIENT_VALIDITY for specifying
the client certificate validity period (in months). Must be an integer
between 1 and 120. Default value is 120. Users can define it as an
environment variable when setting up IKEv2 in auto mode, or when
adding a new IKEv2 client using "--addclient".
- Instead of finding the server's public IP, use the IP address
on the default route if it is not a private IP. This makes VPN
setup slightly faster by skipping IP detection.
- Add a fallback URL for finding the server's public IP.
- Cleanup
- Add an option to skip IKEv2 setup when installing the IPsec VPN.
Example: sudo VPN_SKIP_IKEV2=yes sh vpn.sh
- This allows users to set up an IKEv1-only VPN, or install IKEv2
interactively using "sudo ikev2.sh" after VPN setup.
- Make the VPN setup scripts work on Kali Linux (based on Debian).
- Update IKEv2 helper script to check for OpenSSL 3 first when
exporting the .p12 file.
- The VPN quick start script now supports most of the environment
variables (such as VPN_DNS_SRV1) that are currently supported by
vpnsetup.sh and ikev2.sh. This change enables customization by
advanced users when running the quick start script.
- Show a warning instead of exiting with an error for missing /dev/ppp,
which could happen on Debian 11/10 with certain Linux kernels. Users
can use the IKEv2 or IPsec/XAuth ("Cisco IPsec") mode to connect.
