Allowing TCP -Options through UTM 9

Hi,
I recntly upgraded my Sophos virtual appliance 8 to a virtual version 9 UTM, by exporting and importing the configuration.

Since then my Citrix Repeaters are unable to connect to each other, hence no traffic is accelerated between our companies sites any more.

Citrx technical support claims, this is due to the firewall not allowing TCP-options (options 24 to 31 (decimal) to be precise).
I already disable IPS to be on the safe side, but still no luck.

Is there a way on the UTM9 to allow the forwarding of packets with TCP-options set ?

Regards

Tobias

Thanks, Tobias. The Rulz really represent the combined knowledge of folks here as well as input from Astaro/Sophos Support - all I did was organize.

The accepted wisdom here is what Sascha Paris recommends.
