TNSR Basic Configuration¶
LAN Configuration¶
Set up the LAN interface with a static IP address:
tnsr tnsr# configure
tnsr tnsr(config)# interface GigabitEthernetb/0/0
tnsr tnsr(config-interface)# description LAN
tnsr tnsr(config-interface)# ip address 192.168.0.1/24
tnsr tnsr(config-interface)# enable
tnsr tnsr(config-interface)# exit
tnsr tnsr(config)# exit
WAN Configuration¶
Set up the WAN interface to obtain its IP address via DHCP:
tnsr tnsr# configure
tnsr tnsr(config)# interface GigabitEthernet13/0/0
tnsr tnsr(config-interface)# description WAN
tnsr tnsr(config-interface)# dhcp client ipv4 hostname tnsr
tnsr tnsr(config-interface)# enable
tnsr tnsr(config-interface)# exit
tnsr tnsr(config)# exit
DHCP Server Configuration¶
Set up the DHCP server on the LAN interface with following settings:
Item |
Value |
|---|---|
DHCP IP address pool |
192.168.0.100 to 192.168.0.199 |
Default gateway |
TNSR LAN IP address |
DNS |
8.8.8.8 and 1.1.1.1 |
tnsr tnsr# configure
tnsr tnsr(config)# dhcp4 server
tnsr tnsr(config-kea-dhcp4)# description LAN DHCP
tnsr tnsr(config-kea-dhcp4)# interface listen GigabitEthernetb/0/0
tnsr tnsr(config-kea-dhcp4)# lease lfc-interval 3600
tnsr tnsr(config-kea-dhcp4)# subnet 192.168.0.0/24
tnsr tnsr(config-kea-subnet4)# interface GigabitEthernetb/0/0
tnsr tnsr(config-kea-subnet4)# id 1
tnsr tnsr(config-kea-subnet4)# pool 192.168.0.100-192.168.0.199
tnsr tnsr(config-kea-subnet4-pool)# exit
tnsr tnsr(config-kea-subnet4)# option routers
tnsr tnsr(config-kea-subnet4-opt)# data 192.168.0.1
tnsr tnsr(config-kea-subnet4-opt)# exit
tnsr tnsr(config-kea-subnet4)# option domain-name-servers
tnsr tnsr(config-kea-subnet4-opt)# data 8.8.8.8, 1.1.1.1
tnsr tnsr(config-kea-subnet4-opt)# exit
tnsr tnsr(config-kea-subnet4)# exit
tnsr tnsr(config-kea-dhcp4)# exit
tnsr tnsr(config)# dhcp4 enable
tnsr tnsr(config)# exit
NAT Configuration¶
Create and activate a NAT ruleset that covers the local networks of all peers.
This example has the local networks structured so they all are covered by
192.168.0.0/22.
tnsr tnsr# configure
tnsr(config)# vpf nat ruleset WAN-nat
tnsr(config-vpf-nat-ruleset)# description NAT for WAN
tnsr(config-vpf-nat-ruleset)# rule 1000
tnsr(config-vpf-nat-rule)# description NAT from all internal networks
tnsr(config-vpf-nat-rule)# direction out
tnsr(config-vpf-nat-rule)# dynamic
tnsr(config-vpf-nat-rule)# algorithm ip-hash
tnsr(config-vpf-nat-rule)# from ipv4-prefix 192.168.0.0/22
tnsr(config-vpf-nat-rule)# nat-interface GigabitEthernet13/0/0
tnsr(config-vpf-nat-rule)# exit
tnsr(config-vpf-nat-ruleset)# exit
tnsr(config)# vpf options
tnsr(config-vpf-option)# interface GigabitEthernet13/0/0 nat-ruleset WAN-nat
tnsr(config-vpf-option)# exit
