4f8a19d337 Update OS check 
- Add a check for Ubuntu 18.04 on architectures other than x86_64,
  which is not supported by the VPN scripts for Libreswan 4.9.

2bd37ccf66 Cleanup 
- Save a redirect and make VPN setup slightly faster by using
  raw.githubusercontent.com directly instead of
  https://github.com/hwdsl2/setup-ipsec-vpn/raw/...

4174ffa3ef Improve VPN setup 
- Improve download of VPN helper scripts during setup.
  Note: https://github.com/hwdsl2/setup-ipsec-vpn/raw/master/extras/...
  redirects to
  https://raw.githubusercontent.com/hwdsl2/setup-ipsec-vpn/master/extras/...
  Use the latter directly so that Wget can reuse the same connection
  for all 3 helper scripts.
- For Ubuntu 18.04, improve download of NSS packages and add fallback URLs.

780f815540 Improve VPN setup

  reliability.
- Check and skip installing NSS packages if already installed.

d1da04b1d4 New Libreswan version 
- Support upgrading to Libreswan 4.9.
- Compilation of Libreswan 4.9 on Ubuntu 18.04 requires newer
  versions of NSS packages. They are installed in a similar way
  as apply_ubuntu1804_nss_fix in ikev2setup.sh.

6e596825e2 Improve VPN ciphers 
- Improve security by removing support for modp1536 (DH group 5),
  which is less secure and rarely used by VPN clients. To do this,
  we specify modp2048 on the "ike=" line in ipsec.conf.

025387df91 Improve VPN ciphers 
- Improve security by removing support for modp1024 (DH group 2),
  which is less secure and no longer enabled in Libreswan by default.
- The native VPN client on Android devices uses modp1024 for the
  IPsec/L2TP and IPsec/XAuth ("Cisco IPsec") modes. After this change,
  Android users should instead connect using IKEv2 mode (recommended).

32faed40d5 Improve IP check 
- 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.

4995ec03f5 Improve OS support

  exporting the .p12 file.
