I have Assus TUF AX600, but after upgrade from working 24.10.5 to 25.12.0 somehow nfs stopped working (CIFS mount works), but not nfs 
not even exportfs -ra works
mount: mounting 192.168.1.253:/nfs/Public on /mnt/WD failed: Connection refused
bash: apk info|grep nfs
kmod-fs-nfs
kmod-fs-nfs-common
kmod-fs-nfs-common-rpcsec
kmod-fs-nfs-v3
kmod-fs-nfs-v4
kmod-fs-nfsd
bash: exportfs -ua; exportfs -ra
bash: exportfs: command not found
anyone experienced smth similar - btw: the same mount works with RPI at the same time
THX for any usefull hints
