NimbostratusSNAT / X-FORWARD-FOR breaks HTTPS connection
We are trying to create an iAPP with SSL passthrough and X-FORWARDED set but when we enable SNAT for the X-FORWARDED-FOR (HTTP profile or iRule X-FORWARDED-FOR) the connection seems to stop passing through to our backend IIS pool (nothing logged in the IIS logs).
We have looked through a few guides but it feels like we are missing something or there is an underlying setup flaw with our F5.
Edge / Chrome give the following err_connection_reset
It would seem the minute we enable either; a HTTP Profile, an SSL Profile or enable SNAT the site stops working
I'm sure you will need more info from me, as I'm relatively new to F5's let me know what you need and I'll post the details in
SSL Passthrough is FastL4 setup.
SSL Offload or SSL Offload and Re-Encrypt or in other terms, SSL Bridging are Standard VS setups.
SSL Passthrough cannot alter http data. You cannot perform XFF with fastl4 setup.
I would request you to follow this article to understand more about HTTP traffic.
