NFS share issues with multiple ip on a host

NAS box has a share which is to be mounted on a client


NAS box: myNasBox
Client: SolZone1


NAS box has provided access to the ip/hostname of the host

(SolZone1:/)# nslookup SolZone1
Server:         10.10.134.3
Address:        10.10.134.3#53

Name:   SolZone1.bc
Address: 45.26.20.216

But the mounting failed with permission error

(SolZone1:/)# mount -F nfs -o rw,bg,soft,vers=3 myNasBox:/nasdump/nasdata /nasdata
nfs mount: myNasBox:/nasdump/nasdata: Permission denied


Issue identified as below

(SolZone1:/)# traceroute myNasBox

The traffic comes through the ip 10.12.12.12

(SolZone1:/)# nslookup 10.12.12.12
Server:         10.10.134.3
Address:        10.10.134.3#53

12.142.120.10.in-addr.arpa      name = SolZone1-lb.bc.

Multiple ip's for the host

NAS is adapted to permit the ip 10.12.12.12.

Now the mount is successfull
