This will cover IPsec to Cisco and similar router/firewalls:

 

This guide covers configuration of IPsec between Peplink and Cisco IOS devices using pre-shared key authentication. The example configuration assumes the following settings:

IPsec VPN Settings
Peplink WAN1 IP Address 210.211.10.5
Peplink WAN2 IP Address 88.20.8.20
Peplink LAN Network 192.168.2.0/24
   
Cisco WAN IP Address 66.80.3.1
Cisco LAN Network 192.168.1.0/24
   
Pre Shared Key abc8009008
IPsec Phase 1 Authentication SHA-1
ISPEC Phase 1 Encryption AES-128
ISPEC Phase 1 DH Group 2
IPsec Phase 2 Authentication SHA-1
ISPEC Phase 2 Encryption AES-128
ISPEC Phase 2 PFS Group 2

Using the above example settings from the Cisco, Sonicwall, Etc. Router, we program the Peplink as follows:
