- Improve checking for MOBIKE support. Linux kernels on QNAP systems
do not support MOBIKE.
Ref: https://github.com/hwdsl2/docker-ipsec-vpn-server/issues/247
- Switch to use /etc/ipsec.d/.vpnconfig to store generated password
for IKEv2 client config files, instead of vpnclient.p12.password.
Migrate to use .vpnconfig if the older config file is found.
Ref: 45ee41d
- Improve IKEv2 setup: Save generated password for IKEv2 client
configuration files to vpnclient.p12.password, so that it can
be re-used for later runs of the helper script. Previously,
a different password is generated each time the script is run.
- In rare cases, if a parent process traps SIGPIPE, the 'tr'
command in the VPN setup scripts could output an error
'tr: write error: Broken pipe'. This is a cosmetic error
that does NOT affect the functionality of the scripts. This
commit hides the error in such cases.
- New: Revoke a client certificate using the helper script. Users can
also manually revoke a client certificate, see https://git.io/ikev2
- Check for certificate validity when exporting client configurations
- Delete CRL from IPsec database when removing IKEv2
- Cleanup
- Remove MODP1024 from IKEv2 ciphers for improved security. Windows users
will need to make a one-time registry change before connecting for the
first time. Refer to https://git.io/ikev2.
- Use default key size (2048 bits) when generating key pairs using
certutil. This significantly reduces IKEv2 setup time on servers
with less powerful CPUs, such as Raspberry Pis, while still providing
sufficient security.
- Update docs
- Add variables VPN_DNS_SRV1 and VPN_DNS_SRV2, for specifying custom DNS
servers when running the IKEv2 script in auto mode. Example:
VPN_DNS_SRV1=1.1.1.1 VPN_DNS_SRV2=1.0.0.1 bash ikev2.sh --auto
- Add a variable VPN_DNS_NAME, which can be defined when running the
IKEv2 script in auto mode, to set up IKEv2 using a DNS name instead
of an IP address for the VPN server. The DNS name must be a fully
qualified domain name (FQDN). Example:
VPN_DNS_NAME=vpn.example.com bash ikev2.sh --auto
- Minor cleanup
- Improve output for the VPN setup and upgrade scripts. The outputs
of the scripts are now significantly reduced and only include the
most useful information for users.
- Other minor cleanup
