AltocumulusHelp with Local Traffic Policy with streaming app. and basic understanding.
This is a homelab to have a better understanding of F5 BIG-IP and appercaite any help.
For testing purpose I have setup a PLEX server for streaming service and will be setting up a Horizon View UAGs. I only have one public IP address and thanks to others I have setup a external VIP using a local traffic policy. I am running into couple issues with the policy. I have been doing a lot of reading but still missing something. I created a local traffic policy that matches "HTTP Host to abc.domain.com" that points to a virtual server for PLEX. If the VS is set to use the policy PLEX works via the web interface and the macOS apps works however using PLEX iOS/iPadOS app fails. It does not connect back. I have changed "forward traffic to pool and node" and still same problem. If I change the resourse setting to use "default pool" to the PLEX pool and remove the policy. The app works. I have done a tcpdump on F5 as well proxy capture of an iOS device and cipher suite are correct. I have looked at the ltm log but not seeing any errors. I have made multiple changes with SSL Profile on client/server but no luck. Any suggestions what would cause the app not to work using policy but works when default pool is set? What other troubleshooting should I look at?
Hey, Paulius, thank you again for the tcpdump switches. That helped me find the reset message. I started looking into how to debug this more, which has been a great learning experience. I noticed in the log that when trying from the mobile device, the HTTP_Request for the Host has :443, but accessing from a web GUI or macOS app, it did not. Both policy and iRule had equal to abc.domain.com. I updated the iRule and policy to include or and now it works. See below for iRule. I like the policy features, but it was great to work with iRules too.
if { [HTTP::host] equals "abc.domain.com" or [HTTP::host] equals "abc.domain.com:443" }
