Thanks to Thierry Faidherbe for pointing me to IP resolution. Turned to be
the only entry in client's /etc/hosts. It was:
10.xxx.xxx.xxx   loghost wandaweb01 wandaweb01.mydomain.es

Cahnged to:
10.xxx.xxx.xxx   wandaweb01 wandaweb01.mydomain.es loghost

and now it works.

I think networker was identifying "loghost" as the machine`s hostname, and
"loghost" is (dont know why, wheather I did it or is a default of the
installation process) an alias of the server. Thanks all.
