Is your server behind a NAT firewall...  If so, the request for
publimotion.com.mx will be resolving to your external IP address which,
for requests that originate from the internal network, invariably end up
with your firewall trying to deal with it.

A quick solution would be to add an entry to your hosts file that makes
publimotion.com.mx reference 127.0.0.1.  Alternatively, if you have
other machines running on the network that need to access the server you
will need to set up a DNS server on the network which has the internal
network IP addresses for all internal services, and then make all
internal machines use that DNS server.

Here's the relevant extracts from my config files:

/etc/named.conf
[...]
zone "pythagoras.no-ip.org" {
        type master;
        file "pythagoras_no-ip_org.db";
        allow-update { localhost; };
};

zone "0.168.192.in-addr.arpa" IN {
        type master;
        file "rev.pythagoras_no-ip_org.db";
        allow-update { localhost; };
};
[...]

/etc/dhcpd.conf
[...]
        option routers                  192.168.0.1;
[...]
        option domain-name-servers      192.168.0.2;
[...]

Alternatively, I suppose that you could just make everything on your
server reference localhost - but that looks unprofessional in my opinion.
