# set network tunnel ipsec tunnel-monitor proxy-id. Since PAN-OS 7.0, there is a CLI only configuration command to enable tunnel monitoring for single Proxy-ID:.The above article is based on the default that if we enable tunnel monitoring for IPSec tunnels with multiple Proxy-IDs, the firewall will send the same source/destination monitor probes through each of them.If the above procedure is not possible due to the complexity or Proxy-ID combinations, then you should not enable tunnel monitoring. The remote end, as well as the destination to be monitored, should be part of the peer's local Proxy-ID because the Cisco ASA will not respond to a Palo Alto Networks Proxy-ID message and the tunnel will drop. Pick an unused IP from the local subnet and configure it as a /32 IP address on the tunnel interface.Assign the tunnel interface an IP that belongs to the same subnet as the local subnet mentioned in that Proxy-ID.On the Palo Alto Networks firewall, build a new tunnel interface for every Proxy-ID, so the explicit phase 2 SAs are created and only one SA is bound to one tunnel interface.When the Command Prompt window opens, type pathping and the remote PC’s hostname or IP address 2. Open Command Prompt by typing Cmd in the Windows search bar and then choosing Run as administrator from the right-hand pane 2. Palo Alto Networks devices can monitor on per tunnel basis but not per SA basis. To monitor VPN connection via Command Prompt, here are the steps 1. Palo Alto Networks devices can only source the monitoring packets from the tunnel interface's IP. The ASA enforces strict checks of Proxy-ID and "interesting traffic." Interesting traffic refers to traffic that the Cisco ASA would permit through its SA. The monitor IPs on either ends should be part of the interesting traffic or the actual Proxy-IDsįor the SAs that do not match this monitor packet, the ASA will drop the packet, and since the Palo Alto Networks firewall did not receive a response, the SA would be rekeyed. When tunnel monitoring is enabled, the Palo Alto Networks firewall would send the same monitor packets through all the Phase 2 SAs bound to the same tunnel interface. In multiple Proxy-ID scenarios, there are multiple Phase-2 SAs created, which match each Proxy-ID pairs configured and are bound to the same tunnel. By being in the same network, both agents will communicate with private IP addresses by default.There are multiple Proxy-ID pairs on the Palo Alto Networks firewall that are bound to the same tunnel, but we could enable only one tunnel monitor because the configuration only allows one destination IP and, by default, chooses the tunnel interface IP as its source IP.

GlassWire warns you of network related changes to your PC, or. If for some reason the Remote agent mode is different, make sure to adjust the Client Selection Preference to make sure the Remote agent is the client. Detect spyware, malware, badly behaving apps, and bandwidth hogs, then block their connections. The Remote agent mode should be configured as Client Only because it's that agent that will initiate the connection to the HQ agent. Learn more on the Firewall Configurations. Default network monitoring ports to forward are 23999/TCP and 23999/UDP. On the firewall (or router) facing the HQ agent, port forwarding is required to forward the monitoring traffic from the Internet to the agent. The HQ agent mode must be configured as Private Internet Server because one of the sessions will go through the public Internet. Before we configure the network monitoring sessions, let's go through the Agent Modes and Agent Network configurations for both agents.
