Hi
I´ve NAS Zyxel NSA210 connected to router throught lan. I want to mount some folder from this NAS. Is there some way how to do it?
I searched this forum and found something about smbmount but I didnt found this program on my router (I´ve installed samba - 3.2.15-4)
on NAS is also samba installed

PS: on NSA is also NFS server but I´m not sure if this can help me somehow
