There is no file because the router isn't a Linux distribution.

You'd have to create a User Script which ran mountd/statd with the desired parameter.

i have three questions

first is :in merlin there is a `nfs export` panel which has a switch on/off the nfs service
dose it means if i need specific some parameters i need close the `nfs export` panel switch on. and use my own userscript to start the nfs service? how to start nfs serivce by myself,i have download the nfs_export.asp file but only find some navam_get and some function didn't find some nfs start code,it's hard for me.

two is: there is a nfsv4 version which could already specific the port which could use nfs under a firewall,but merlin didn't support nfsv4,is this true

three is:as you mentioned mountd/statd with specific parameters & custom userscript,could give me a sample code?

thanks
