I've succesfully mounted my unraid server read-only over wan to a particular client (port forwarding 111, 2049 and a high port) with:

 

sudo mount -t nfs -o vers=3,ro,rsize=32768,nolock,soft,async,intr,noatime,mountport=xxxxx wan.ip:/mnt/user/sharename/path /local/path

 

But the speed was much slower than when I mounted my linux mint machine behind the same router with the same params.

 

With /etc/exports having

-async,no_subtree_check,anongid=0,anonuid=0,all_squash,fsid=100 client.wan.ip(ro,insecure)

mounting my linux mint machine yields full upload speed of ~1.2MB/s but when I mount unraid with the same parameters, a dd copy from a mounted folder to /dev/null gives a speed of about 300kB/s no matter what block size used.

 

nfsstat shows badcalls badauth if that helps

 

What files can I tweak/fix in unraid's nfs server? What other info should I look at? Note: mounting unraid locally is fine and fast so it's something between unraid and its router. iperf between unraid and remote client also gives full speed

 

Thanks in advance
