Relatively green concerning this subject. Ill try to explain my issue as plainly as I can. I used to have a pair BigIP 3600 LTM's that I had the reverse proxy Irule version 4.11 set up for my PI servers to use as a gateway to get outbound for Microsoft updates, etc. The Bigip's were running V11. I have recently upgraded my hardware to I5600's running version 13.1 and the proxy doesnt work anymore. Ive tried various solutions that ive seen here but none are the same and none seem to work either. I need help figuring out if its something in the load balancer setups before I go yelling at my network guys. Any help would be much appreciated.
Anyone? A link to follow? A word of wisdom?
Might I suggest you open a ticket with F5 Technical Support? More details, like configuration settings and network traces, are probably necessary for anyone to do more than just speculate as to the cause. Since you've tried all the usual suspects, I think it's your best bet.
Open a case with support. A lot of data is required for analysis.
