udp port sunrpc unreachable

[Ingo Lantschner <ingo.lists@vum.at>]

Hi all,
I have a propably simple problem here - but can not find a solution:
NFS-Client wslisi should mount a directory from NFS-Server wsvideo. 
Potmaper und nfs-common are installed on both machines. The server has 
nfs-kernel-server installed:
-------------------------------------------------------------------------
wsvideo$ env LANG=C dpkg -l nfs*
...
un  nfs-client                       <none>
ii  nfs-common                       1.0.6-3.1ubuntu1
ii  nfs-kernel-server                1.0.6-3.1ubuntu1
--------------------------------------------------------------------------

But I still can not connect - tcpdump says that port 111 (sunrpc) is not 
reachable:
-------------------------------------------------------------------------
# tcpdump -t not port 22
IP wslisi.696 > wsvideo.sunrpc: S 727126627:727126627(0) win 5840 <mss 
1460,sackOK,timestamp 2256871 0,nop,wscale 2>
IP wsvideo.sunrpc > wslisi.696: R 0:0(0) ack 727126628 win 0
IP wslisi.697 > wsvideo.sunrpc: UDP, length: 56

arp who-has wsvideo tell wslisi
arp reply wsvideo is-at 00:0c:76:71:02:09
arp who-has fw tell wsvideo
arp reply fw is-at 00:4f:4e:05:d1:bd
--------------------------------------------------------------------------

netstat sees tcp open:

--------------------------------------------------------------------------
$ env LANG=C netstat -an | grep 111
tcp        0      0 127.0.0.1:111           0.0.0.0:*           LISTEN
udp        0      0 127.0.0.1:111           0.0.0.0:*
--------------------------------------------------------------------------

Any idea? TIA Ingo.
