1 year ago I couldn’t get connected to my office’s network using my VPN client. The reason was that my p12 certificate was expired. AFAIK IPsec cannot renew certificates automatically as windows VPN client does. To make it work I needed to renew it using the windows client and then migrate a p12 certificate to a Linux/IPsec friendly format. As I was in a little hurry I tried installing the Linux Citrix client
In that email the user was referring to very useful tutorial: Check Point Firewall-1 NG(X). I remembered that link as I used it to configure my first road warrior VPN client. But this document is outdated as the procedure to obtain the private key is not valid anymore. There is a new procedure that I documented in my personal wiki. In this post I am gonna copy & paste the right procedure from it.
