VyOS

Tento návod poskytuje informace o konfiguraci a ukázkovou šablonu pro použití zařízení VyOS s konfigurací IPsec.

Poznámky

vti <NAME_OF_VTI_INTERFACE>: Určuje virtuální rozhraní tunelu IPsec.
esp-group <NAME_OF_ESP_GROUP>: Šifruje provoz procházející tunelem pomocí konkrétní zásady nebo profilu ESP.
ike-group <NAME_OF_IKE_GROUP>: Vyměňuje klíče pomocí konkrétní zásady nebo profilu IKE.
IP adresy rozhraní tunelu IPsec na obou koncích tunelu by měly tvořit dvojici privátních IP adres (RFC 1918) ve stejné /31 nebo /30 podsíť a zadejte spojení Point-to-Point Link.
Endpoint tunelu IPsec na tomto routeru VyOS je <IP_ADDR_OF_UPLINK_INTF_TO_INTERNET/WAN>.
IP adresa endpointu tunelu IPsec na straně Cloudflare je jedna z anycast IP adres přiřazených vašemu účtu, které najdete v Pronajaté IP adresy ↗.
Tento router je nakonfigurován tak, aby inicioval připojení tunelu IPsec.
