Linux mount NFS with specific user
I was searching hours on the Internet, but for this specific problem I could not find any solution.
1: I have a Xubuntu Linux on my PC. I use it in average way: browse the Internet, watch videos, etc. And also it gives home for my PHPStorm app but no the project files. This is the HOST. It has a host-only network: 192.168.56.1
2: I have a VirtualBox Debian Linux (no GUI) system. This meant to be represent a development version of my real webserver. It has all the project files. This VM is on an external drive, so I can take it everywhere (e.g.: to the office). 192.168.56.101. This is the GUEST.
3: on the HOST I use dnsmasq to force every *.dev domain to be redirected to the GUEST. So I can test my projects easily.
4: on the GUEST I exported the /var/www folder in the /etc/exports:
/var/www 192.168.56.1(rw,sync,no_root_squash,no_subtree_check)
The problem: I want to use the PHPStorm on the HOST to edit the files on the GUEST "locally". But I cannot mount the GUEST's /var/www folder into the HOST's /home/gabor/Projects folder with full permissions. I tried to use the following:
$> sudo mount 192.168.56.101:/var/www /home/gabor/Projects
This looks okay for the first time, but the folder is mounted with nobody:nogoup and I have no permissions to edit.
I want the /home/gabor/Projects has the owner gabor:gabor and everything I create in this folder must has the owner www-data:www-data on the Debian side. But for NFS mounting I cannot specify the user.
$> sudo mount -o umask=0022,gid=1000,uid=1000 192.168.56.101:/var/www /home/gabor/Projects
mount.nfs: an incorrect mount option was specified
I also failed to mount --bind the /var/www with different user (should be nobody:nogroup) on the Debian, so that I could export that one...
How can I solve this problem? Please help me. Thank you.

NFS v2 and v3 do not support uid/gid.
