NFS mount internal error

Question

I have a server that I use for NFS share. 4 servers use it without a problem. I configured a new server and that can't mount. I get this error

   mount.nfs: internal error

In the logfile of the client:

   nfs: server 192.168.1.100 not responding, timed out

On the server I opened the ports I need, and in the log I can see this:

   rpc.mountd[20520]: authenticated mount request from 192.168.1.10:824 for /mnt/nfs/archive/server05 (/mnt/nfs/archive)

iptables rules on the nfs server:

    -A INPUT -s 192.168.1.10/32 -p tcp -m tcp --dport 1:1024 -j ACCEPT 
    -A INPUT -s 192.168.1.10/32 -p udp -m udp --dport 1:1024 -j ACCEPT 
    -A INPUT -s 192.168.1.10/32 -p tcp -m tcp --dport 32803 -j ACCEPT

    -A INPUT -s 192.168.1.10/32 -p udp -m udp --dport 8125 -j ACCEPT

hosts.allow

    [root@nfs_server]# cat /etc/hosts.allow
    portmap:ALL
    lockd:ALL
    mountd:ALL
    rquotad:ALL
    statd:ALL

If I stop iptables it works.

I have tried many things and searched for a long time. Please help...

`If I stop iptables it works.` Stopping it on the client? The server? Both? — Sven, May 25 '16 at 13:14
Also if I open all the ports for the client on the nfs server it works, so probably I'm missing a port but I don't know which. — atakacs, May 25 '16 at 13:34

Per redhat.com - 9.7.3 Running NFS Behind a Firewall -

Procedure 9.1. Configure a firewall to allow NFS

Allow TCP and UDP port 2049 for NFS.
Allow TCP and UDP port 111 (rpcbind/sunrpc).
Allow the TCP and UDP port specified with MOUNTD_PORT="port"
Allow the TCP and UDP port specified with STATD_PORT="port"
Allow the TCP port specified with LOCKD_TCPPORT="port"
Allow the UDP port specified with LOCKD_UDPPORT="port"

As I said, I searched for a long time and tried everything. I have done that already RQUOTAD_PORT=875 LOCKD_TCPPORT=32803 LOCKD_UDPPORT=32769 MOUNTD_PORT=892 STATD_PORT=662 STATD_OUTGOING_PORT=2020 – atakacs May 26 '16 at 07:26
