2024-04-22 05:44:46 Wang Xuancong description nfs mount over VPN tunnel does not work while other nfs mount works. I have physical network interface eth0 on 192.168.101.1, and OpenVPN tunnel tun0 on 20.8.0.1. If I try to nfs mount over VPN, I get the following error: ``` root@wxc-dell:/# mount -v 20.8.0.1:/netboot/nfs /mnt/a mount.nfs: timeout set for Fri Apr 19 13:27:51 2024 mount.nfs: trying text-based options 'vers=4.2,addr=20.8.0.1,clientaddr=20.8.0.1' mount.nfs: mount(2): No such file or directory mount.nfs: trying text-based options 'addr=20.8.0.1' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: trying 20.8.0.1 prog 100003 vers 3 prot TCP port 2049 mount.nfs: prog 100005, trying vers=3, prot=17 mount.nfs: trying 20.8.0.1 prog 100005 vers 3 prot UDP port 49387 mount.nfs: mount(2): Permission denied mount.nfs: mounting 20.8.0.1:/netboot/nfs failed, reason given by server: No such file or directory ``` If I downgrade nfs-kernel-server from 2.6.1-1ubuntu1.2 to Debian Bullseye's version (1.3.4-6), then everything works.
