IPSec VPN tunnel not coming up

jac101 — Tue, 12 Dec 2017 04:06:25 GMT

I configured IPSec VPN tunnel between my 2 PA FWs. The physical interfaces are up but the tunnel is not up. I am a Cisco guy and new to the PA. I am trying to see ipvpn traffic va the Monitor. But I did not see any traffic. How do I check for my ike phase 1 and ipsec phase 2 to make sure that all the parameters and the password matched on both side. Also, how do I need which side is the initiator and which side is the receiver? Thanks

hi @jac101

have you checked this article: Getting Started: VPN ?

you can initiate from one peer by running

> test vpn ike-sa gateway <gateway>

> test vpn ipsec-sa tunnel <value>

the best place to start looking is in the 'system' log, the responder should have most information you need to fix configuration mismatches

How do I need which FW is the receiver?

if you execute the commands on firewall A, firewall B will be the receiver

I did the commands from my main FW. So the next step is to go to the remote FW and look at the Monitor. Correct?

5220A(active)> test vpn ike-sa gateway PHASE1-gtw2

Start time: Dec.12 10:28:45
Initiate 1 IKE SA.

5220A(active)> test vpn ipsec-sa tunnel PHASE2-tunnel

Start time: Dec.12 10:29:18
Initiate 1 IPSec SA for tunnel PHASE2-tunnel.

correct, you should now see the negotiation taking place on the remote peer and see more info regarding what is succeeding and what is failing

you can access the system logs and filter for ( subtype eq vpn )
