Only FreeBSD machines are on the network. It all works as expected until I give the address 192.168.0.121 to a client machine. This machine is not able to mount remote file systems via NFS despite this IP address is specifically mentioned in /etc/exports. I know that some routers/switches use this address as the default. But I run into this problem even when I connect the NFS server and the client directly. I do not need to use this address but I would like to know why it does not work. Showmount for the specific NFS mount point shows this: /usr/home 192.168.0.121 192.168.0.122 192.168.0.99 192.168.0.112 192.168.0.116 192.168.0.117 192.168.0.118 192.168.0.119 192.168.0.120 192.168.0.123 192.168.0.124 192.168.0.125 192.168.0.126 192.168.0.127 192.168.0.128 192.168.0.129 /etc/hosts.allow says this as the first effective line: ALL : ALL : allow Does anybody has an idea what could cause this?
