Configuring a Basic L2TP VPN in the CLI
Use the following procedures to use the command-line interface to configure a remote access VPN for L2TP
IPsec:
1. Define the authentication method and server addresses:
(host)(config) #vpdn group l2tp
enable
client configuration {dns|wins} <ipaddr1> [<ipaddr2>]
2. Enable authentication methods for IKEv1 clients:
vpdn group l2tp ppp authentication {cache-securid|chap|eap|mschap|mschapv2|pap
3. Create address pools:
(host)(config) #ip local pool <pool> <start-ipaddr> <end-ipaddr>
4. Configure source NAT:
(host)(config) #ip access-list session srcnatuser any any src-nat pool <pool> position 1
5. If you are configuring a VPN to support machine authentication using certificates, define server certificates
for VPN clients using IKEv1:
(host)(config) #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:
(host)(config) #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 in the WebUI
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 “Working with IKEv2 Clients on page 339."
Use the following procedures to in the WebUI configure a remote access VPN for IKEv2 clients using
certificates.
