Pfsense 2.1 vpn ipsec tunnel to azure

[Miguelino]

Hi. I have been able to establish a vpn ipsec to Windows Azure. Initially proper operation, the networks of each site are visible but there are a problem when I move files between sites. Copying files, especially large files, are stuck  and  cut. I tried with different values ​​in the MSS claping but solves nothing. Can anyone experience this behaviour. Thank you.
