setup Checkpoint Firewall VPN with SNX on Linux Fedora 25
First you have to ensure the Java JRE is installed on your system.
Remember the java plugin will only work on Firefox. If you prefer to install from fedora/rhel repos:
sudo dnf (yum) install java-1.8.0-openjdk icedtea-web
download the snx script installer from the Checkpoint VPN page:
https://<your company vpn ip addr>/sslvpn/SNX/INSTALL/snx_install.sh
run int as root to install
sudo /usr/bin/snx --help
