ESR Series Routers Operation Manual
esr(config-object-group-service)#
port-range 500
esr(config-object-group-service)#
exit
Create a static route to the remote LAN. For each subnet located behind an IPsec tunnel, specify a
route via VTI tunnel:
esr(config)#
ip route 192.0.2.0/24 tunnel vti 1
Create IKE protocol profile. In the profile, select Diffie-Hellman group 2, AES 128 bit encryption
algorithm, MD5 authentication algorithm. Use the following parameters to secure IKE connection:
esr(config)#
security ike proposal ike_prop1
esr(config-ike-proposal)#
dh-group 2
esr(config-ike-proposal)#
authentication algorithm md5
esr(config-ike-proposal)#
encryption algorithm aes128
esr(config-ike-proposal)#
exit
Create IKE protocol policy. For the policy, specify the list of IKE protocol profiles that may be used
for node and authentication key negotiation:
esr(config)#
security ike policy ike_pol1
esr(config-ike-policy)#
pre-shared-key hexadecimal 123FFF
esr(config-ike-policy)#
proposal ike_prop1
esr(config-ike-policy)#
exit
Create IKE protocol gateway. For this profile, specify VTI tunnel, policy, protocol version and mode
of traffic redirection into the tunnel.
esr(config)#
security ike gateway ike_gw1
esr(config-ike-gw)#
ike-policy ike_pol1
esr(config-ike-gw)#
mode route-based
esr(config-ike-gw)#
bind-interface vti 1
esr(config-ike-gw)#
version v2-only
esr(config-ike-gw)#
exit
Create security parameters' profile for IPsec tunnel. For the profile, select AES 128 bit encryption
algorithm, MD5 authentication algorithm. Use the following parameters to secure IPsec tunnel:
esr(config)#
security ipsec proposal ipsec_prop1
esr(config-ipsec-proposal)#
authentication algorithm md5
esr(config-ipsec-proposal)#
encryption algorithm aes128
esr(config-ipsec-proposal)#
exit
Create policy for IPsec tunnel. For the policy, specify the list of IPsec tunnel profiles that may be
used for node negotiation:
esr(config)#
security ipsec policy ipsec_pol1
esr(config-ipsec-policy)#
proposal ipsec_prop1
esr(config-ipsec-policy)#
exit
Create IPsec VPN. For VPN, specify IKE protocol gateway, IPsec tunnel policy, key exchange mode
and connection establishment method. When all parameters are entered, enable tunnel using
enable
command.
esr(config)#
security ipsec vpn ipsec1
esr(config-ipsec-vpn)#
mode ike
esr(config-ipsec-vpn)#
ike establish-tunnel immediate
esr(config-ipsec-vpn)#
ike gateway ike_gw1
esr(config-ipsec-vpn)#
ike ipsec-policy ipsec_pol1
esr(config-ipsec-vpn)#
enable
esr(config-ipsec-vpn)#
exit
