Timeout: No Response from client-server

Hi

I have two server-rooms (DZ-A and DZ-B)

in DZ-A there is a server called client-server and in a DZ-B there is a 
monitoring server called monitoring-server.

if i do in monitoring-server i got:
~# snmpwalk -c sw client-server -v1
Timeout: No Response from client-server
~#
I have a connection between monitoring-server and client-server:
15:23:00 root[load: 0.14]@monitoring-server ~# ping client-server
PING client-server (xxx.xxx.xxx.xxx) 56(84) bytes of data.
64 bytes from client-server (xxx.xxx.xxx.xxx): icmp_seq=1 ttl=56 
time=1.23 ms
...

--- client-server ping statistics ---

so looks like there are no connection and firewall problems

client-server snmpd.local.conf:
com2sec local client-server sw
com2sec local xxx.xxx.xxx.xxx (<-- client-server IP) sw
com2sec local monitoring-server sw


group MyRWGroup any             local

view all    included  .1                               80

access MyROGroup ""      any       noauth    exact  all    none   none
access MyRWGroup ""      any       noauth    exact  all    all    none


SNMPD is running: root     24039  0.0  0.8   8992  4248 ?        S    
May06   0:05 /usr/sbin/snmpd -Lsd -p /var/run/snmpd.pid
and in both servers: NET-SNMP version:  5.4.2.1

Any ideas?
