SOLVED NFS mount behind pfSense

[fahadshery]

Hi,

I have my TrueNas running at 192.168.1.100 and another machine on a difference subnet i.e. 192.168.2.100. Both of these networks are managed via VLANs on pfSense.
I understand that if I need to mount a NFS share then both networks should be able to talk to each other. But I just want to open up NFS ports only for 192.168.2.100 machine so that it could mount the share.
Any ideas, which ports to open? I have already allowed TCP and UDP port 2049 for NFS. But I am still unable to mount the NFS share on 192.168.2.100.
Is there any other configuration I need to do on TrueNas side?

Many thanks,

This is how I resolved it:

1. check the ports truenas listening at by rpcinfo -p
2. I opened Ports 2049, 111, 716
3. Make sure some ports are for TCP and some are for UDP. Step 1 will tell you which ports to open with which protocol

that's it!
