Create a virtual server for web traffic over QUIC

You can create a virtual server on the BIG-IP system to manage web traffic that uses the transport-layer protocol QUIC instead of TCP. Once deployed, this virtual server causes the system to: listen for secure client web traffic sent over QUIC and UDP, decrypt the traffic, and forward the decrypted traffic to an application server pool over TCP.

  1. On the Main tab, click Local Traffic > Virtual Servers. This displays a list of virtual servers on the system.
  2. Click Create.
  3. Type a name for the virtual server, such as my_vs_quic.
  4. From the Type list, select Standard.
  5. In the Source Address box, confirm that Host is selected, and type the address 0.0.0.0.
  6. In the Destination Address/Mask box, confirm that Host is selected, and type an IP address in CIDR format. The netmask you specify must be /32 (that is, 255.255.255.255).
  7. From the Service Port list, select HTTPS.
  8. From the State list, confirm that Enabled is selected.
  9. From the Configuration list, select Advanced.
  10. From the Protocol list, select UDP.
  11. From the Protocol Profile (Client) list, confirm that udp is selected.
  12. From the Protocol Profile (Server) list, select an existing TCP profile. Note: F5 recommends that you select the default profile f5-tcp-lan.
  13. For the HTTP Profile (Client) setting, confirm that the default profile http is selected.
  14. For the HTTP Profile (Server) setting, confirm that (Use Client Profile) is selected.
  15. For the SSL Profile (Client) setting, select clientssl-quic.
  16. From the Source Address Translation list, select Auto Map.
  17. For the Address Translation setting, confirm that the Enabled check box is selected.
  18. For the Port Translation setting, confirm that the Enabled check box is selected.
  19. In the Acceleration area of the screen, for the HTTP MRF Router setting, select the check box.
  20. For the QUIC Profile setting, select the QUIC profile that you previously created.
  21. From the HTTP3 Profile list, select the HTTP3 profile you previously created.
  22. From the Default Pool list, select the name of the web server pool you created earlier.
  23. Click Finished.
