        Hello,

after upgrading one of my systems from Debian 11 to 12 the kernel NFS server
doesn't seem to accept NFS requests over UDP on port 2049 anymore:

        >rpcinfo -p | grep nfs
            100003    3   tcp   2049  nfs
            100003    4   tcp   2049  nfs
            100227    3   tcp   2049  nfs_acl

This causes problems for a non-Linux NFS client whose automounter
tries to perform the mount over UDP. Is there a way to re-enable
the UDP port?

        Kind regards

Edit /etc/nfs.conf file:
[nfsd]
udp=y

then:
sudo systemctl restart nfs-server

Result:
$ rpcinfo -p | grep nfs
    100003    3   tcp   2049  nfs
    100003    4   tcp   2049  nfs
    100227    3   tcp   2049  nfs_acl
    100003    3   udp   2049  nfs
    100227    3   udp   2049  nfs_acl
