I also noticed this Why the ID says "any identifier" if I established the IP in both? [image: 1723251693398-d9a3b80c-6d46-495e-abc2-20f99c573b89-image.png]

@datacare There are no responses from the opposite end. Remeber IKE uses UDP, and can transmit several packets it considers “data” without any preceeding “connection” being made as with TCP. Notice there are no packets recieved from the other end - so you need to investigate that, and why :-)

@planedrop don't load pn the ipsec tunnel.

can you share P2 subnet/IPs of both end, and firewall rule configured on IPSec interface - both ends,

@rsdu Even though the documentation states that firewall rules are added automatically, firewall log shows that incoming traffic is blocked by the "default IPv6 incoming block" rule. I added UDP Port 500 and ESP to the ruleset and there we go ...

@Mr_JinX system logs............ ipsec logs........... Unless you didn't provide the logs on purpose its impossible to say why anything happens anywhere.

After taking the screenshot, and recognizing the mismatch between the ports, I've updated the PHASE1 settings on both ends, specifying just the NAT-T port.

@viragomann Thanks for helping me. Your tip worked for me.

@lifeboy When editing the Phase one and Phase 2 settings, only one encryption settings is enabled in both: AES256 and using SHA256 with DH14: [image: 1721142730850-72a1546e-02d3-4f89-bebe-3fc688c05aec-image-resized.png] [image: 1721142765204-937960d9-5daa-465f-a6f4-630ecdc079ac-image-resized.png]

@viragomann Hello @viragomann Please see details logs on attachment filelog-ipsec-details-pfsense.txt Thank you for your help Regards

turns out, it was me. i mistakenly upgraded the secondary node to 2.7.2, but forgot to upgrade the primary node and it was still 2.7.0. HAsync was not working due to this error, so this was not a pfsense problem, it was a me problem :)

@michmoor i've founf the problem. When my p1 have multiple p2. It always getting disconnected. I dont know why its happening on latest pfsense version.

@viragomann Before routing the traffic of Server, I would like PFSense01 and PFSense02 to ping on the VTI interfaces, because from the screenshot that I showed before on PFSense01 there are 0 outbound packets, and I don't now why
