Some users cannot sign in to windows live messenger even though others can. here's my relevant config: #Msn messenger acl msn urlpath_regex -i gateway.dll acl msnd dstdomain acl msn dstdomain 64.4.13.0/24 152.163.241.0/24 64.12.163.0/24 207.46.110.0/24 207.46.1.0/24 65.54.0.0/16 207.46.104.20 207.46.110.0 messenger.msn.com gateway.messenger.hotmail.com g.live.com live.com acl msn1 req_mime_type application/x-msn-messenger http_access allow msnd http_access allow msn http_access allow msn1 and added port 1863 to SSL PORTS in access.log when i filter by IP of the user trying to sign in to WLM, nothing is denied. all his hits go through... Firewall config: All ports are denied. Any help would be appreciated. Thanks, --Roland
