IPSec Synology RT1900ac setup


New Member
Hi everyone,

i'm just looking for a bit of help setting up an ipsec connection on my synology router because i found out that my ISP is throttling my OpenVPN connections as i get full isp speed with ipsec and only half speed with OpenVPN (not CPU related as i have only 20Mbps isp and tried it both on my Computer and router - same results)

I'm having a hard time figuring out if i need to open some ports and how to do it properly.
Also which authentification protocol i must chosse (MS CHAP v2?)

Thanks for any help.
