no LAN traffic to NAS when on VPN

Hello,

I have a RB2011UAS-IN for a VPN to a commercial VPN provider. With NAT etc… So the local addresses it is giving out are:

DHCP: 192.168.1.10 - 248
NAS IP: 192.168.1.2 (fixed)
Deafult gateway (on the MK): 192.168.1.253. The real (ADSL) modem is 192.168.1.254, NO DHCP.


The following happens:

  1. VPN traffic works flawless. All the clients connected to the router, they all go through the VPN to the outside world (that is how it supposed to be).
  2. NAS (Netgear) on the LAN can be pinged.
  3. FTP connection to the NAS is possible.
  4. Mapping the network drive in Windows (\192.168.1.2\backup) takes VERY VERY long time (+/- 1-2 minutes), but eventually, it maps the drive.
  5. Mapped drive (for example P:) is NOT accessible. Windows gives a timeout.
  6. Printing to a network printer (fixed IP 192.168.1.249) works fine.

I would like to access the NAS from Windows. When I remove the MK router (and enable DHCP on the DSL modem), everything works fine (NAS is accessible at full speed).


What can be the problem? I suspect the firewall, since the FTP and ping are going through.

What needs to be changed?

No one?

Maybe more information is needed?
