Hi, Dan. Thanks for your reply.

I was reviewing on the CLI as through the web access if the router
(Zyxel P-660R-T1v3) allows to disable the negotiation of the LAN
interface, but I found nothing. So I tried the other suggestion, that it
was changing the cable, but no change in behavior.
I did some other tests with my notebook:
a) notebook (orion) <---> firewall (alderamin)
b) notebook (orion) <---> router
Case a: notebook (orion) <---> firewall (alderamin)

It seems that here the connection notebook <---> firewall has not worked
with auto-negotiation on both sides. Now I try to disable the

That is, it seems that the communication notebook <---> router works
well regardless of the type of negotiation on the notebook side.
But when I reconnect the firewall to the router, I lose again the link,
regardless of whether on the firewall is enabled or not the
auto-negotiation.
