set interfaces ethernet eth0 address 60.0.0.10/24 set interfaces ethernet eth1 address 192.168.10.1/24 set system offload timeout 30 set protocols static route 0.0.0.0/0 next-hop 60.0.0.20 set vpn ipsec auth-profile AUTH-SA local auth pre-shared-secret test set vpn ipsec esp-group CHILD-SA proposal 1 encryption aes256gcm128 set vpn ipsec esp-group CHILD-SA proposal 1 pfs dh-group19 set vpn ipsec ike-group IKE-SA key-exchange ikev2 set vpn ipsec ike-group IKE-SA proposal 1 dh-group 19 set vpn ipsec ike-group IKE-SA proposal 1 encryption aes256gcm128 set vpn ipsec ike-group IKE-SA proposal 1 hash sha256 set vpn ipsec site-to-site peer PEER default-esp-group CHILD-SA set vpn ipsec site-to-site peer PEER auth-profile AUTH-SA set vpn ipsec site-to-site peer PEER ike-group IKE-SA set vpn ipsec site-to-site peer PEER connection-type on-demand set vpn ipsec site-to-site peer PEER local-address 60.0.0.10 set vpn ipsec site-to-site peer PEER remote-address 60.0.0.20 set vpn ipsec site-to-site peer PEER tunnel 1 local prefix 192.168.10.0/24 set vpn ipsec site-to-site peer PEER tunnel 1 remote prefix 192.168.20.0/24
Step 2: Set the following configuration in DUT1:
set interfaces ethernet eth0 address 60.0.0.20/24 set interfaces ethernet eth1 address 192.168.20.1/24 set system offload timeout 30 set vpn ipsec auth-profile AUTH-SA local auth pre-shared-secret test set vpn ipsec esp-group CHILD-SA proposal 1 encryption aes256gcm128 set vpn ipsec esp-group CHILD-SA proposal 1 pfs dh-group19 set vpn ipsec ike-group IKE-SA key-exchange ikev2 set vpn ipsec ike-group IKE-SA proposal 1 dh-group 19 set vpn ipsec ike-group IKE-SA proposal 1 encryption aes256gcm128 set vpn ipsec ike-group IKE-SA proposal 1 hash sha256 set vpn ipsec site-to-site peer PEER default-esp-group CHILD-SA set vpn ipsec site-to-site peer PEER auth-profile AUTH-SA set vpn ipsec site-to-site peer PEER ike-group IKE-SA set vpn ipsec site-to-site peer PEER connection-type initiate set vpn ipsec site-to-site peer PEER local-address 60.0.0.20 set vpn ipsec site-to-site peer PEER remote-address 60.0.0.10 set vpn ipsec site-to-site peer PEER tunnel 1 local prefix 192.168.20.0/24 set vpn ipsec site-to-site peer PEER tunnel 1 remote prefix 192.168.10.0/24 set protocols static route 0.0.0.0/0 next-hop 60.0.0.10
Step 3: Run command vpn ipsec show sa at DUT0 and check if output contains the following tokens:
INSTALLEDShow output

Step 4: Set the following configuration in DUT2:
set interfaces ethernet eth0 address 192.168.10.2/24 set protocols static route 0.0.0.0/0 next-hop 192.168.10.1
Step 5: Ping IP address 192.168.20.1 from DUT2:
admin@DUT2$ ping 192.168.20.1 count 1 size 56 timeout 1Show output
PING 192.168.20.1 (192.168.20.1) 56(84) bytes of data. 64 bytes from 192.168.20.1: icmp_seq=1 ttl=63 time=0.993 ms --- 192.168.20.1 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.993/0.993/0.993/0.000 ms
Step 6: Run command system conntrack clear at DUT0.
Step 7: Initiate a udp connection from DUT2 to DUT1 and try to send some messages between both endpoints
admin@DUT1$ monitor test connection server 5050 udp local-address 192.168.20.1 admin@DUT2$ monitor test connection client 192.168.20.1 5050 udp source-port 6060
Step 8: Run command system conntrack show at DUT0 and check if output matches the following regular expressions:

Step 9: Run command system conntrack clear at DUT0.
Step 10: Initiate a udp connection from DUT1 to DUT2 and try to send some messages between both endpoints
admin@DUT2$ monitor test connection server 5050 udp local-address 192.168.10.2 admin@DUT1$ monitor test connection client 192.168.10.2 5050 udp source-port 6060 local-address 192.168.20.1
Step 11: Initiate a udp connection from DUT2 to DUT1 and try to send some messages between both endpoints
admin@DUT1$ monitor test connection server 6060 udp local-address 192.168.20.1 admin@DUT2$ monitor test connection client 192.168.20.1 6060 udp source-port 5050
Step 12: Run command system conntrack show at DUT0 and check if output matches the following regular expressions:
