ip tcp adjust-mss on FTD with FMC

Hi all,

I'm working on setting up an IKEv2/IPSec VPN tunnel from an FTD (6.2) managed by FMC to Azure.  The tunnel is up and icmp is working fine but our server engineer is reporting issues with RDP and domain controller replication.

We're wondering if MTU or MSS could be causing these issues.  The FTD interface MTU are currently default (1500) but I don't see a way to set ip tcp-adjust mss on the FTD. I'm not sure if there's a way to do this in FMC or via the FTD command line.

Thanks.
