Guerreiros de estrada são usuários que viajam com clientes móveis com um endereço IP atribuído dinamicamente, como os laptops. Os clientes móveis autenticam usando certificados.
O exemplo a seguir mostra a configuração para IKEv2, e evita o uso do protocolo IKEv1 XAUTH.
No servidor:
conn roadwarriors
ikev2=insist
# Support (roaming) MOBIKE clients (RFC 4555)
mobike=yes
fragmentation=yes
left=1.2.3.4
# if access to the LAN is given, enable this, otherwise use 0.0.0.0/0
# leftsubnet=10.10.0.0/16
leftsubnet=0.0.0.0/0
leftcert=gw.example.com
leftid=%fromcert
leftxauthserver=yes
leftmodecfgserver=yes
right=%any
# trust our own Certificate Agency
rightca=%same
# pick an IP address pool to assign to remote users
# 100.64.0.0/16 prevents RFC1918 clashes when remote users are behind NAT
rightaddresspool=100.64.13.100-100.64.13.254
# if you want remote clients to use some local DNS zones and servers
modecfgdns="1.2.3.4, 5.6.7.8"
modecfgdomains="internal.company.com, corp"
rightxauthclient=yes
rightmodecfgclient=yes
authby=rsasig
# optionally, run the client X.509 ID through pam to allow/deny client
# pam-authorize=yes
# load connection, don't initiate
auto=add
# kill vanished roadwarriors
dpddelay=1m
dpdtimeout=5m
dpdaction=clear
conn roadwarriors
ikev2=insist
# Support (roaming) MOBIKE clients (RFC 4555)
mobike=yes
fragmentation=yes
left=1.2.3.4
# if access to the LAN is given, enable this, otherwise use 0.0.0.0/0
# leftsubnet=10.10.0.0/16
leftsubnet=0.0.0.0/0
leftcert=gw.example.com
leftid=%fromcert
leftxauthserver=yes
leftmodecfgserver=yes
right=%any
# trust our own Certificate Agency
rightca=%same
# pick an IP address pool to assign to remote users
# 100.64.0.0/16 prevents RFC1918 clashes when remote users are behind NAT
rightaddresspool=100.64.13.100-100.64.13.254
# if you want remote clients to use some local DNS zones and servers
modecfgdns="1.2.3.4, 5.6.7.8"
modecfgdomains="internal.company.com, corp"

No cliente móvel, o dispositivo do guerreiro da estrada, utiliza uma pequena variação da configuração anterior:
conn to-vpn-server
ikev2=insist
# pick up our dynamic IP
left=%defaultroute
leftsubnet=0.0.0.0/0
leftcert=myname.example.com
leftid=%fromcert
leftmodecfgclient=yes
# right can also be a DNS hostname
right=1.2.3.4
# if access to the remote LAN is required, enable this, otherwise use 0.0.0.0/0
# rightsubnet=10.10.0.0/16
rightsubnet=0.0.0.0/0
fragmentation=yes
# trust our own Certificate Agency
rightca=%same
authby=rsasig
# allow narrowing to the server’s suggested assigned IP and remote subnet
narrowing=yes
# Support (roaming) MOBIKE clients (RFC 4555)
mobike=yes
# Initiate connection
auto=start
conn to-vpn-server
ikev2=insist
# pick up our dynamic IP
left=%defaultroute
leftsubnet=0.0.0.0/0
leftcert=myname.example.com
leftid=%fromcert
leftmodecfgclient=yes
# right can also be a DNS hostname
right=1.2.3.4
# if access to the remote LAN is required, enable this, otherwise use 0.0.0.0/0
# rightsubnet=10.10.0.0/16
rightsubnet=0.0.0.0/0
fragmentation=yes
# trust our own Certificate Agency
rightca=%same
authby=rsasig
# allow narrowing to the server’s suggested assigned IP and remote subnet
narrowing=yes
# Support (roaming) MOBIKE clients (RFC 4555)
mobike=yes
# Initiate connection
auto=start
