We have a Star VPN with 3rd Party Cisco ASA firewall (interoperable device). The VPN is up and stable and able to pass traffic between encryption domains. We are experiencing an intermittent issue when traffic is initiated from the Cisco side to a resource on our Checkpoint side, when it needs to traverse our Mesh VPN network.
When the Source connects to resource that goes over 2 VPN connections, it fails on the first and sometimes second attempt but successfully connects the third attempt. It never connects the first time. There are no drops on FW-A or FW-B.
Source -> Cisco ASA -> Star VPN -> Checkpoint FW-A -> Resource
Source -> Cisco ASA -> Star VPN -> Checkpoint FW-A -> Mesh VPN -> Checkpoint FW-B -> Resource
Has anyone run into this?
