Own a premium PureVPN account The Juniper Networks® SA2500, SA4500, and SA6500 SSL VPN Appliances meet the needs of companies of all sizes. SA Series SSL VPN Appliances use SSL, the security protocol found in all standard Web browsers. The use of SSL eliminates the need for pre-installed client software, changes to internal servers, and costly ongoing maintenance and desktop Forward these ports to the IP address that is assigned to the external interface of your VPN server. If you're routing traffic inbound and performing NAT at or behind the VPN server, then you must open your firewall rules to allow UDP ports 500 and 4500 inbound to the external IP address applied to the public interface on the VPN server. Redirect Universal Datagram Protocol (UDP) ports 500 and 4500 to the VPN server. Configure routing so that the DNS servers and VPN servers can reach the Internet. This deployment uses IKEv2 and Network Address Translation (NAT). Make sure that the VPN server can reach all of the required internal networks and network resources. If two vpn routers are behind a nat device or either one of them, then you will need to do NAT traversal which uses port 4500 to successfully establish the complete IPEC tunnel over NAT devices. pantelis1 Edited by Admin February 16, 2020 at 2:30 AM
Feb 15, 2018 · A VPN routing table is called a VPN routing/forwarding (VRF) table. With the VRF-lite feature, the Catalyst 4500 series switch supports multiple VPN routing/forwarding instances in customer edge devices. (VRF-lite is also termed multi-VRF CE, or multi-VRF Customer Edge Device).
First thing you need to make sure is you have the following command :. crypto ipsec nat-transparency udp-encapsulation. Secondly, make sure the other router ahead of this device is doing one to one nat for this IP. As long as crypto map is applied to correct interface, we should see correct UDP port.. If this does not help, can you please share complete debugs (do sanitize the IPs accordingly VPN and Port Forwarding of UDP 4500 - Cisco Community
When a user starts a Mobile VPN with IKEv2 connection: The VPN client starts a connection on port UDP 500. If that port is not open on the client gateway, the session does not proceed. If port UDP 500 is open, but NAT is detected, the connection proceeds on port UDP 4500. If the client gateway does not allow UDP 4500, IPSec and IKEv2 cannot

When ipsec vpn connection is established it only shows that it is connected on port 4500 not 500? is this default behaviour? Initally when it was establishing theVPN connection it was showing both udp 500 and 4500 ports. Regards. MAhesh
