The problem is that the translation does not show up and traffic from the outside does not work, until the host 188.8.131.52 sends traffic out from the inside. Then the translation is there and traffic initiated from the outside works.
From everything I read this is not how it is supposed to work. The clear xlate removes the static nat entries!!!
No, a static will not show up in the XLATE table untill an actual translation takes place. Does the static show up in your config? I have heard of a similar problem that after adding a static, it does not show in the config but I think it was with PIX code 6.2. Can I see your full config?
