What is NCP exclusive client?

The NCP Exclusive Remote Access Client is part of the NCP Exclusive Remote Access solution for Juniper SRX Series Gateways. The VPN client is only available with NCP Exclusive Remote Access Management. Use the NCP Exclusive Client to establish secure, IPsec -based data links from any location when connected with SRX Series Gateways.

What is SRX traffic selector?

Traffic selectors configured on the SRX Series device and the NCP client determine the client traffic that is sent through the IPsec VPN tunnel. Traffic in and out of the tunnel is allowed only for the negotiated traffic selectors. If the route lookup for a packet’s destination address points to an st0 interface (on which traffic selectors are configured) and the packet’s traffic selector does not match the negotiated traffic selector, the packet is dropped. Multiple Phase 2 IPsec SAs and auto route insertion (ARI) are supported with the NCP Exclusive Remote Access Client. Traffic selector flexible match with port and protocols is not supported. For this feature, the remote address of the traffic selector must be 0.0.0.0/0.

What is TCP encapsulation profile?

On an SRX Series device, a TCP encapsulation profile defines the data encapsulation operation for remote access clients. Multiple TCP encapsulation profiles can be configured to handle different sets of clients. For each profile, the following information is configured:

How many times can you send a message on NCP?

The default DPD settings on the NCP Exclusive Remote Access Client specify sending messages at 20-second intervals for a maximum of eight times. When chassis cluster failover occurs, the SRX Series devices might not recover within the parameters specified by the DPD settings and the tunnel goes down. In this case, increase the DPD interval on the NCP Exclusive Remote Access Client to 60 seconds.

What is an ARI in a VPN?

After the tunnel is established, auto route insertion (ARI) automatically inserts a static route to the remote client’s IP address so that traffic from behind the SRX Series device can be sent into the VPN tunnel to the client’s IP address.

What happens if you exceed the license limit on SRX?

This means that a remote access user can connect to the SRX Series device and IKE and IPsec SAs can be established, but if the user exceeds the licensed user limit, the user is disconnected.

What port is secure remote access?

Secure remote access is ensured even when a device between the client and the gateway blocks Internet Key Exchange (IKE) (UDP port 500).
