Osx Ipsec Vpn Client

The instructions below demonstrate how to connect to the VPN service using native functionality for Mac OSX.

This looks like a very annoying and longstanding bug in Mac OS X/macOS. Mac OS X Snow Leopard added the support for Cisco IPSec VPN connections – that is, plain IPSec with XAuth authentication and modecfg. That makes it two layers of authentication: first, Machine Authentication with a password (Shared Secret) or an X509 certificate. Then a traditional username-password pair for XAuth, both of which you can enter and save in the Account Name and Password fields respectively when you set up the connection. Trouble is, even though you entered your password and it is apparently saved in the keychain properly, Mac OS X keeps nagging you to manually enter the password every time you connect. Turns out this is a just bug with a simple fix. Open the Keychain Access Application, select the System keychain and find your saved XAuth password entry in the list.
