WiNG 7.6 AP310 dropping tcp keep-alive after roaming

[Jacek_Skorzewsk]

Hi, I have an issue with locally bridged trafiic on AP310 running WiNG 7.6.

The wifi client has a MSSQL database (tcp) session open.
The session goes idle, the server starts keeping the seession up by sending tcp keep-alive packets.

When roaming occurs, no tcp keep-alive ACK’s are seen from the wireless station.
Could it be firewall-policy behaviour? Stateful L2 packet inspection is enabled.

Cheers

Jacek

Hello, 

It is possible that the firewall is impacting the session. Please see this article for the suggested WiNG firewall configuration: https://extremeportal.force.com/ExtrArticleDetail?an=000087636

If this does not resolve theissue it is suggested to open up a Support case with GTAC for further analysis with a TechSupport from the Controller.
