Dear All, 

 

I was trying to setup VPN IPsec between Fortigate and SRX, but it didn't work at all.. 

 

I got the IPSec logs from Fortigate,  and found this 

ike 0:VPN-GW:225: sent IKE msg (ident_r1send): FORTIGW:500->SRX-GW:500, len=152, id=6c1c70d3deab4bab/31f33050dfa3e739 ike 0:VPN-GW:224: negotiation timeout, deleting

 

it looks  it has tried to send reply of 1st message, but it failed for some reason, 

i'm not 100% sure if it's correct, 

 

Do you have any idea how i can troubleshoot this case and if there's any other reason why negotiation failed ?

Configure ike v2 on Fortigate instead of ike v1 You need to make sure that the configuration is exactly the same for the vpn to come up. Please confirm the proxy id on the Juniper device as it needs to be the same on both the sides.

Proxy id in Juniper=Quick mode selector in Fortigate. You can efer to the following link to configure the site to site vpn [link]https://www.youtube.com/watch?v=sZC0AldHi34[/link] Routes and the policies have to be in place for the vpn to come up.

Hi, 

I can see packet drop or remote location not replying to the packet

sent IKE msg (P1_RETRANSMIT): FORTIGW:500->SRX-GW:500, If any of device is behind the NAT then check port forwarding and NAT-T configuration. Best suggestion to check the remote site device debugging also. So you will get a clear picture. What is going on between two devices? Is there any VPN blocked by ISP? Regards, Deepak Kumar
