5. If you are configuring a VPN to support machine authentication using certificates, define server certificates
for VPN clients using IKEv1.
For IKEv1: crypto-local isakmp server-certificate <cert>
6. If you are configuring a VPN to support IKEv1 Clients using pre-shared keys, you can configure a global IKE
key by entering 0.0.0.0 for both the address and netmask parameters in the command below, or configure an
IKE key for an individual subnet by specifying the IP address and netmask for that subnet.
crypto isakmp key <key> address <ipaddr|> netmask <mask>
7. Define IKE Policies:
crypto isakmp policy <priority>
encryption {3des|aes128|aes192|aes256|des}
version v1|v2
authentication {pre-share|rsa-sig|ecdsa-256ecdsa-384}
group {1|2|19|20}
hash {md5|sha|sha1-96|sha2-256-128|sha2-384-192}
lifetime <seconds>
Configuring a VPN for L2TP/IPsec with IKEv2
Only clients running Windows 7, StrongSwan 4.3 and Dell VIA support IKEv2. For additional information on the
authentication types supported by these clients, see ““IKEv2 Clients” on page391”.
In the WebUI
Use the following procedures to use the WebUI configure a remote access VPN for IKEv2 clients using
certificates.
“Define Authentication Method and Server Addresses” on page397
“Define Address Pools” on page397
“Enable Source NAT” on page398
“Select Certificates” on page398
“Configure IKE Policies” on page398
“Set the IPsec Dynamic Map” on page399
“Finalize your WebUI changes” on page400
Define Authentication Method and Server Addresses
1. First, define the authentication method and server addresses
2. Navigate to Configuration> Advanced Services > VPN Services and click the IPSEC tab.
3. To enable L2TP, select Enable L2TP (this is enabled by default).
4. Select the authentication method for IKEv1 clients. Currently supported methods are:
Password Authentication Protocol (PAP)
Extensible Authentication Protocol (EAP)
Challenge Handshake Authentication Protocol (CHAP)
Microsoft Challenge Handshake Authentication Protocol (MSCHAP)
5. Configure the IP addresses of the primary and secondary Domain Name System (DNS) servers and primary
and secondary Windows Internet Naming Service (WINS) Server that will be pushed to the VPN client.
Define Address Pools
Next, define the pool from which the clients are assigned addresses.
