FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic.
This article describes how to fix high latency and packet loss issues over Telstra satellite WAN connection in SD-WAN setup.
High latency and packet loss over Satellite WAN connection under the performance SLA of SD-WAN will lead to link down issues.
Since the satellite link latency is very large, it is necessary to modify the interval(default 500ms), probe-timeout(default 500ms), and SLA of health-check as follows:
# config health-check edit "SLA_Profile_ID" set server <server1_IP_address> set interval 1600 set probe-timeout 1600 set members 0 # config sla edit 1 set latency-threshold 1000 set jitter-threshold 800 set packetloss-threshold 5 next end next end
The Fortinet Security Fabric brings together the concepts of convergence and consolidation to provide comprehensive cybersecurity protection for all users, devices, and applications and across all network edges.
