Description

This article provides information about the ports that can be used by Junos Pulse for dynamic VPN.

Symptoms

Can any other port, apart from port 443, be configured for dynamic VPN?

Solution

  • No other port can be configured for dynamic VPN (initial web-auth). For dynamic VPN requests, the JSRX device has to listen on port 443.

  • JSRX dynamic VPN client (Junos Pulse) initiates a connection on port 443 for web-auth, and when web-auth is passed, it starts the phase-1 negotiation and xauth process.

  • The Junos Pulse client does not have an option to configure the port on which it has to send the request; it is hard coded.

  • If a customer needs the option to configure dynamic VPN on any other port apart from port 443, the customer must contact the Juniper Accounts team to file an Enhancement Request.
