Cable modem–>pfsense-->Switch-->hosts & and problem server

Logically:

WAN-->Router(192.168.11.1)-->Switch(192.168.11.28)--> Problem Server (NVR) (192.168.11.29)

When using the VPN

• I can't access the switch config page over VPN

• I can't access the Network Video Recorder using the NVR client over VPN

• I can access the NVR client using tightVNC, but I receive a connection error

• I can access the webpage of all IP cameras

The NVR software & switch seems to be suffering from a strange one way communication problem over the VPN but work fine on the LAN. When accessing the switch config page it seems to be trying to load but never does and eventually finishes loading after a few minutes but displays nothing (chrome); just a white screen, no error messages from chrome. When running ping on a IP camera over VPN:

When using trace route to any accessible host over VPN I get this, dont know if this is normal:

Tracing route to 192.168.11.77 over a maximum of 30 hops

The NVR network settings are as follows:

Subnet: 255.255.255.0
Default Gateway: 192.168.11.1

Here is a trace route to the non-accessible NVR, the same results for the switch:

Trace complete.

• Why cant I access the switch setup page over vpn?

• Why cant I use the NVR client software over vpn?

Any help would be appreciated guys, thanks in advance.
