F5 LTM / Riverbed / Exchange 2010 Disconnect and Reconnect
All of our remote users get disconnected and then reconnected when using that setup. If we take F5 out of the loop over the WAN, their connection is fine. However, if we take Riverbed out of the loop and go directly to the F5 their connection to Exchange 2010 is also fine.
F5 support is baffled and cannot find an anwser. Same with Riverbed.
- Scott_81793NimbostratusWe have the exact same issue. I'm unclear as to what the final config/fix was on both the F5 and Riverbed. Which of the following changes were made to resolve?
F5
- change the Exch2010 rpc VIP to FastL4 with a idle timeout of 7200 seconds
Riverbed
- change riverbed to allow Exch2010 traffic to pass through without modification
- update riverbed code to version ?
Also - were you able to fix the Directory disconnect issues or did this just take care of the Mail disconnects?
- JTrimbleNimbostratusAs I said, the work around that we implemented to fix the issue was to put a rule on the Riverbed to ignore traffic to/from the F5 Outlook RPC VIP. We have since worked with Riverbed on a proper solution:
https://support.riverbed.com/kb/sol...yName=MAPIAs for the directory disconnects, no I did not solve that yet. It appears to be isolated to Windows 7 clients, or at least Windows 7 clients appear to be more affected than Windows XP clients. Since we don't officially support Windows 7 in the office yet I haven't made it a priority to fix. I am certainly interested though if anyone else has solved that particular issue. - Simon_Beirne_84NimbostratusDid the upgrade to >=6.5.1 RiOS fix the issue?
- JTrimbleNimbostratusYes the upgrade to RiOS fixed the Riverbed problem.
- Thomas_Schocka1AltocumulusHi JTrimble,
- JTrimbleNimbostratus
As far as I know, there are only Avaya switches between the users and the F5 devices, so I don't see where additional SNAT's would be in the picture. Increasing the timeout for RPCs on the F5 resolved our problems though. I think it was defaulted for something like 5 minutes and I increased it to 2 hours.
