Hi, web gui don't have access to internet, I could install by console setting the http_proxy var, but the web gui dont download by example, the access control list.
Sorry but your question is unintelligible. If english is your second language then maybe try using the appropriate section and write your problem in your native tongue.
If what your trying to do is access the web GUI from a WAN then you need to create a rule to allow that.
firewall -->Rules-->WAN
