Good day,
We have recently replaced a FortiGate firewall with a new Juniper SRX345. Networking-wise everything is working fine, however we are getting issues with e VPN connection to a Cisco SA520W. The VPN was working fine on the FortiGate, and no changes were made at the Cisco end. The configuration is attached.
We see the tunnels coming up, however we cannot reach the remote subnet. We also notice there are multiple IKE tunnels, where there should only be one. The tunnels sometimes keep adding up. Output attached.
We have also attached the logs. Any help/input would be appreciated. Thanks.
