RV180 VPN file transfer failure

[James2015]

Every time i try to transfer a file over VPN of approx. 5mb or more the transfer fails with the error code 0x8007003B. Does anyone know what might be the cause?

You don't mention what the cisco router or device is...

The router is a RV180, as mentioned in the subject of the issue.

I've now solved this, it was due to SMB 3.02 not working over a VPN in Windows 8.1. This is a windows issue. By forcing the transfer to work under SMB 1 it works fine.
