Could you try giving the "tcp" or "udp" flags as well as "nfsvers=3" or
similar? It might be that it simply isn't reaching the portmapper.
Baseline:
mount: mount to NFS server 'esb' failed: RPC Error: Success.
nfsvers=3 makes no difference:
mount: mount to NFS server 'esb' failed: RPC Error: Success.
tcp fails in a new way:
mount.nfs: Input/output error
That failure is explained by the current iptables rule on the gateway,
which only forwards udp for nfs:
iptables -t nat -A PREROUTING -p udp -d 122.47.72.148 --dport 4000 -j
DNAT --to 192.168.0.5:2049
upd: works!
Please close -- but this should be documented (or the default changed to
what used to be in effect before nfs-common 1.1.0-6).
Tested and confirmed to work on 1.1.0-6, 1.1.0-10, and 1.1.0-11.
