MVPrbunix This link seems to be a similar situation to yours.
I'm not 100% positive this will resolve your issue because you do not have an html profile applied based on your configuration that you provided.
NimbostratusHello Paulius! Thanks for sharing that link, I actually saw that link earlier and tried to debug from there but I don't have nothing configured in the VIP so guess it must be something different.
Thanks anyway!
MVPrbunix You might consider performing the same troubleshooting that they did in the referenced article to see if something similar is happening. It could be that the F5 isn't agreeing to the compression and that is why it isn't passing to the user compressed. If you are not able to figure this one out you could open an F5 case to see if they can assist. I would imagine that in addition to the QKVIEW they will want captures of the communication both from the client to the VS and from the F5 to the pool member. You should be able to get this all in one tcpdump by doing the following because it will follow the connection through the SNAT that occurs and it will add additional fields that show what the F5 is doing with the connection as it passes through it. You could also add on "-w <directory_path_with_filename>" to the end and save the capture so you can provide it to F5.
tcpdump -nni 0.0:nnp host <client_IP>
