I would like to recommend below path:
eLearnSecurity (eJPT and eWAPT or ePTP) --> OSCP
eLearnSecurity is growing in numbers and provide you very comprahensive tools and learning resources.
After getting some grasp with basics try to practice on some machines good websites:
1. Hack The Box
2. Vulnhub
3. Check over the wire website
4. Watch IPSec videos on Youtube.
Good luck!
