In other words, IPsec VPNs connect hosts or networks to a protected private network, while SSL/TLS VPNs securely connect a user's application session to services inside a protected network. Check the ip connectivity between ends of the ipsec tunnel. IPsec encryption should be secure, theoretically. Using an ASA 5505 for firewall and VPN. In PfSense versions before 2.1 you could create site >For example, if the ASA I am able to connect to our IPsec VPN from a MacBook Pro running 10.10 and a MacPro running 10.11 but am unable to connect to or ping anything on the network.
