Hi.

The most safe way, I believe is to get that information by running an internet "query".

You can try this:

httpClient lo_client
integer li_ret, li_StatusCode
long ll_ret
string ls_url
string ls_data
string ls_ret

ls_url = 'http://ipinfo.io/ip'

lo_client = Create httpClient
ll_ret = lo_client.sendrequest('get',ls_url)
li_StatusCode = lo_client.GetResponseStatusCode()

ls_ret = lo_client.GetResponseStatusText( )
li_ret = lo_client.getresponsebody(  ls_data)
destroy lo_client

messagebox("", ls_ret)
messagebox("", ls_data)

return

ls_data should contain you external ip.
