CirrusLTM Policy based External VServer. New need: use it also as proxy for PostgreSQL DB
Hi! I got some new challenge for my F5. I have F5 Act/Stb cluster running in Azure, 16.1.3 Big-IP software version. F5 has been divided into 1 external VServer that has LTM policies defined. Base...
I get that for http protocols, but you cannot read an http header on a PostgreSQL connection. Is there an option for NO HTTP host? If so, try that.. although, you'll forward every garbage packet, too.
I understand adherance to design, as well, but maybe that's the design for http. You can resolve your issue right now by creating a new "external VS" that listens on the appropriate port and selects the primary DB box. If you're concerned about things like persistence, maybe enable universal persistence, if needed.

Doable, but breaks the scheme.
Currently we have there 1 External VServer and 41 Internal VServers.External VServer gets the request, checks HTTP Host URL and redirects traffic to Internal VServer X
(small example below):I'd like to keep this way without making exceptions if possible. I need to have it scalable
I don't know if next week there could be another - new - PostreSQL DB proxy necessary
