Will enterprise site-to-site VPN or SDWAN appliances work on Starlink?


Yes. Like client VPN applications, NAT traversal support via TCP or UDP is required on the Starlink side of the VPN/SDWAN appliance. VPNs that rely on protocols 47 (GRE), 50 (ESP), 51 (AH), 115 (L2TP) are dropped by CGNAT at this time.
