    Until recently I had configured PPTP and L2TP. They were ending at the different devices (PPTP - SBS 2011, L2TP - Zyxel USG 100 ) I have now strange behavior, I can connect and browse for some folders but not larger (by size) . To be even stranger some client can browse and some cannot. 

    So I installed SSTP to avoid different ports that needs to be opened, and it takes longer time to load and display folders than PPTP and L2TP. I saw that sometimes this slow behavior can cause NOD32 antivirus , mine is AVIRA. 

    Can someone please help. I read that this can be because of MTU. Do I need to change MTU on both SBS and Zyxel or client side ?

    Thanks

    After some testing here are the results:

    L2TP, IPsec, they behave the same (tunnels terminates one device - Zyxel USG 100 ). I can connect to the remote location, I am able not to browse folders (I don't know what happened but this problem disappeared, sometimes I was not able to browse just bigger folders) but I have a problem with copy paste (but just for files larger than - 1 MB, if I try to copy shortcut I can do that without the problem), windows starts calculating ..... and nothing. If I use FTP software this goes without the problem.

    Sometimes like now I managed to transfer picture file 2.5MB but it took about 5 min to do that.

    Also deleting files >1MB takes ethernity.

    So if FTP is working but windows copy paste not , that means that tunnel in total is OK and there is a problem with SMB. Am I right ?

    Please help, this problem is killing me...

    Thanks

    On the client machine I have Avira and on the server there is no antivirus, but that is virtual machine (but PPTP doesn't have any similar problems).

    Thanks

    Hi, it was firmware of Zyxel router. After I installed newest update, everything is working.
