otherwise goes to internet.

as announced in my previous mails, I migrated all my proxies servers
last night. this ran fine and the packages are running well.
I updated access ntlm rule by removing 'all' at the end of the line but
this does not chnage anything except it happened at most 37 times on one
of of the proxies. I got this more than 100 times a day before.

so can I still try something else ?
