@Medster87 Have you done switch acl? If yes. My-bee you have close your self out from the network.

@ZIZOU94 yes normaly. but you cant only open port you have to port nat in to ER605. UDP port 500 for Internet Key Exchange (IKE) to manage encryption keys, and UDP port 4500 for IPSec NAT-Traversal...

@ZIZOU94 I did a google search but didn't find any answers. but you are not alone, there were many people who did not get the vpn to work since there is no dh group configuration on liveboks, you...

@ZIZOU94 ok, look right, but the story don't tel anything about dh group on livebox orange you use dh14 on ER605 but what group on livebox orange

@ZIZOU94 what is phase 1 settings on ER605? screenshot

@ZIZOU94 I don't know what you have on the other end of the vpn but SHA2-256 SHA-256 should be the same. but there are many other parameters in a VPN tunnel that must match for it to work.
