IKEv2 (iOS Only)
This VPN connection type is supported on iOS devices.
Internet Key Exchange version 2 (IKEv2) is the default VPN setting for iOS. The IKEv2 is used to create a security association in the IPSec (Internet Protocol Security) suite. A security association (SA) establishes shared security attributes between two network entities to support secure communication.
Use the following guidelines to configure the IKEv2 VPN connection type.
Within these selections, you may make settings for:
iOS VPN configurations using IKEv2 need to include a selected value from the following list of certificate types:
- RSA
- ECDSA256
- ECDSA384
- ECDSA512
The ED25519 certificate type is not supported.

On Demand Rules
Applicable to: iOS 7 and later
Whenever a network change is detected, the VPN On Demand service compares the newly connected network against the match network criteria specified in each set of rules (in order) to determine whether VPN On Demand should be allowed or not on the newly-joined network.
Rule sets are checked sequentially, beginning with the first. A rule set matches the current network only if all of the specified policies in that rule set match.
If a rule set matches the current network, a server probe is sent if a URL is specified in the profile. VPN then acts according to the policy defined in the dictionary (for example, Allow, Ignore, Evaluate Connection, Connect, or Disconnect).
Define sets of evaluation rules for each action that can be taken by VPN On Demand: Allow, Connect, Disconnect, Evaluate Connection, and Ignore. You can define more than one set of rules for each type of action that can be taken. For each set of evaluation rules, the number of rules defined for that set is indicated in the No. of Rules column.
Procedure
-
Select Add+ to add a new set of On Demand evaluation rules.
A rule creation dialog box opens.
-
From the On Demand Action drop-down list, select the action you want to be taken when the rules you create below are matched.
The following actions are available:
•Allow: (Deprecated by iOS.) Allow VPN On Demand to connect if triggered.
•Connect: Unconditionally initiate a VPN connection on the next network attempt.
•Disconnect: Tear down the VPN connection and do not reconnect on demand as long as this dictionary matches.
•Evaluate Connection: Evaluate the action parameters for each connection attempt.
•Ignore: Leave any existing VPN connection up, but do not reconnect on demand as long as this dictionary matches.
-
Matching Rules - For each rule you create, enter one of the following types:
•DNS domain: This rule matches if any of the domain names in the specified list matches any domain in the device’s search domains list. A wildcard '*' prefix is supported. For example, *.example.com matches against either mydomain.example.com or yourdomain.example.com.
•DNS Server Address: This rule matches if any of the network’s specified DNS servers match any entry in the list. Matching with a single wildcard is supported. For example, 17.* matches any DNS server in the class A 17 subnet.
•SSID: A list of SSIDs to match against the current network. If the network is not a Wi-Fi network, or if the SSID does not appear in this list, the match fails. Omit this rule and the corresponding list to match against any SSID.
•Interface Type: If specified, this rule matches only if the primary network interface hardware matches the specified interface type. Choose Ethernet, Wifi, or Cellular.
•URL String Probe: A URL to probe. If this URL is successfully fetched without redirection (returning a 200 HTTP status code), this rule matches.
- Enter a value for each rule type and an optional description.
- After adding your rules, select OK.
Default Rules
Define a default rule that simply specifies a default VPN On Demand action in case none of the On Demand rules match, or if no On Demand rules have been defined.
Procedure
- From the On Demand Action drop-down list, select the action you want to be taken by default, if none of the rules match or none are defined.
-
Select Add+ to add a default rule.
The following actions are available:
•Allow: (Deprecated by iOS.) Allow VPN On Demand to connect if triggered.
•Connect: Unconditionally initiate a VPN connection on the next network attempt.
•Disconnect: Tear down the VPN connection and do not reconnect on demand as long as this dictionary matches.
•Evaluate Connection: Evaluate the action parameters for each connection attempt.
•Ignore: Leave any existing VPN connection up, but do not reconnect on demand as long as this dictionary matches.
If you select Evaluate Connection, a domain actions table displays:
-
Select Add+ to add a domain action.
The Action Parameters dialog box opens.
-
From the Domain Action drop-down list, select one of the following actions to be taken for the domains listed in the table:
•Connect if needed: The specified domains should trigger a VPN connection attempt if domain name resolution fails, such as when the DNS server indicates that it cannot resolve the domain, responds with a redirection to a different server, or fails to respond (timeout).
•Never connect: The specified domains should never trigger a VPN connection attempt.
-
Select Add+ to include any of the following evaluation types:
•Domain: The domains for which this evaluation applies.
•Required DNS Server: IP addresses of DNS servers to be used for resolving the specified domains. These servers need not be part of the device’s current network configuration. If these DNS servers are not reachable, a VPN connection is established in response. These DNS servers should be either internal DNS servers or trusted external DNS servers. You can only configure required DNS server evaluation types for the Connect if needed domain action.
•Required URL Probe: An HTTP or HTTPS (preferred) URL to probe, using a GET request. If no HTTP response code is received from the server, a VPN connection is established in response. You can only configure required URL probe evaluation types for the Connect if needed domain action.
- Add a value and optional description for each entry.
- Select OK to save your domain action parameters.
