Okay, so something *is* listening on port 2049 of <FreeNAS-IP> (confirmed with netstat -an4).

I can ping both ways successfully.
Both machines are on the same physical switch.
Both are on the same subnet, same netmask, etc.
Source (VMware ESXi) says "Unable to contact NFS server"
ESXi firewall disabled with " esxcli network firewall set --enabled false "
FreeNAS /var/log/messages has three entries like
mountd[pid]: mount request successful from <IP> for <mountpoint>

This is really annoying. What else can I try/check?

I'm trying to get FreeNAS (based on FreeBSD) to serve up NFS shares. It keep failing with

nfsd: Can't bind to tcp addr *: Address already in use

Which doesn't make sense. I tried binding to a specific address (the IP address of this server) and I get the same message, but with the IP address instead of *.

No other services are running on this server, other than http (80). Where do I start?

Thanks,
