May 03, 2012Virtual Server send an R flag and reset the connection
Hello my dear friends!
I've used this forum multiple times and you guys have helped me a lot in some of the weird issues I have had!
So here I go again....
When I hit my VS I see the 3 way handshake taking place.... Then I see a P flag but my VS returns an R flag and terminates the connection before I can actually reach my pool members
Please see a small tcpdump I capture that ilustrates my problem
root@f5-dmz1-dc1:/S1-green-P:Active] config tcpdump -i vlan_ext_dmz_sofia dst host 172.25.9.37 and dst port 8480

I tried to change setting in the TCP profile Im using with out positive results :S
Anyone facing an issue like this before?
Where I am right now id 3:00 in the morning and I've been awake for 18 straight hours now and Im running out of ideas here...
Any suggestion will be highly appreciated!!
