when the route to a particular network is via a Secure Tunnel (ST) virtual interface. With a route based VPN, there is no particular policy tied to a VPN tunnel, rather traffic is forwarded across a tunnel link based on the routing table. Set routing-options static route 10.32.197.64/28 qualified-next-hop st0.Here’s how to build a simple route based IPSec VPN between two Juniper SRX gateways. Set security ipsec vpn test-bk0 establish-tunnels immediately Set security ipsec vpn test-bk0 ike ipsec-policy phase2 Set security ipsec vpn test-bk0 ike gateway test-bk0 Set security ipsec vpn test-bk0 vpn-monitor source-interface reth0.102 Set security ipsec vpn test-bk0 vpn-monitor optimized Set security ipsec vpn test-bk0 vpn-monitor destination-ip 10.32.197.65 Set security ipsec vpn test-bk0 bind-interface st0.10 Set security ike gateway test-bk0 external-interface reth0.101 Set security ike gateway test-bk0 dynamic hostname test-bk0 Set security ike gateway test-bk0 ike-policy test-bk0 Set security ike policy test-bk0 pre-shared-key ascii-text dl-test-bk0-123 Set security ike policy test-bk0 proposal-set standard Set security ike policy test-bk0 description "DL test" Set security ike policy test-bk0 mode aggressive Set security zones security-zone Untrust interfaces st0.10 Set interfaces st0.10 family inet mtu 1400 Set interfaces st0.10 description "DL test" Here is my configuration on SSG, i also attached a ike-trace log file: Is there any problem from Behind NAT configuration? There is something wrong in setting as "No proposal chosen" at IKE (Phase 1). I did a careful check as your recommends for days, but it's still found that #set security ike traceoptions file ike-trace You can configure the same using the below commands. If they match with the settings on the SRX then we will need IKE Traceoptions on the SRX side to proceed further. Value in Identity (ID) Payload expected by peer (IP address or hostname.Could you please check the below settings on the peer side and compare it with the settings on the SRX. Now coming to the error you have got now after the changing the locala identity from test-bko to IP address 192.168.1.5 looks lile there was some attribute sent from our side in the first packet which was not accepted by the peer. Please confirm if the issue was phase 1 and 2 both not coming up or only phase 2 not coming up. I looked through the original post you have made and found that IKE SA to be UP in the output of "show security ike security-associations detail".

I searched a lot but not to solve my problem which shows “negotiation failed with error: SA unusable”. My SRX is behind a NAT device that has a dynamic IP address. I got a profile VPN from SSG and config VPN on my SRX.
