CentOS上にSquidを構築しプロキシ・サーバー経由でインターネットアクセスをしております。 そこでSkypeを使用しチャットは使用出来ていますが通話やビデオ通話が出来ません。 通話ボタンを押すと画面が切り替わりますが"接続中"と表示されたままになってしまいます。 squid.confの下記の行をコメントアウトしたりiptablesをstopしてテストしてみましたが結果は変わりませんでした。 http_access deny !Safe_ports プロキシ・サーバーやSkype接続端末は同セグメントの192.168.1.0/24に属しています。 プロキシ・サーバーはLANカード２枚差しで一つは上記セグメント、 もう一つは外抜け用のセグメントになっています。 ご教授よろしくお願い致します。 squid.confの中身は以下のとおりです。 ------------ # # Recommended minimum configuration: # acl manager proto cache_object acl localhost src 127.0.0.1/32 ::1 acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1 # Example rule allowing access from your local networks. # Adapt to list your (internal) IP networks from where browsing # should be allowed acl localnet src 10.0.0.0/8 # RFC1918 possible internal network acl localnet src 172.16.0.0/12 # RFC1918 possible internal network acl localnet src 192.168.0.0/16 # RFC1918 possible internal network acl localnet src fc00::/7 # RFC 4193 local private network range acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines acl lan src 192.168.1.0/24 # acl Safe_ports port 21 # ftp acl Safe_ports port 80 # http acl Safe_ports port 443 # https acl Safe_ports port 1025-65535 # unregistered ports acl CONNECT method CONNECT acl numeric_IPs url_regex ^(([0-9]+\.[0-9]+\.[0-9]+\.[0-9]+)|(\[([0-9a-f]+)?:([0-9a-f:]+)?:([0-9a-f]+|0-9\.]+)?\])):443 acl Skype_UA browser ^skype http_access allow CONNECT localnet numeric_IPs Skype_UA # # Recommended minimum Access Permission configuration: # # Only allow cachemgr access from localhost http_access allow manager localhost http_access deny manager # Deny requests to certain unsafe ports http_access deny !Safe_ports # Deny CONNECT to other than secure SSL ports #http_access deny CONNECT !SSL_ports # We strongly recommend the following be uncommented to protect innocent # web applications running on the proxy server who think the only # one who can access services on "localhost" is a local user #http_access deny to_localhost # # INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS # # Example rule allowing access from your local networks. # Adapt localnet in the ACL section to list your (internal) IP networks # from where browsing should be allowed http_access allow localnet http_access allow localhost http_access allow lan # And finally deny all other access to this proxy http_access deny all # Squid normally listens to port 3128 #http_port 3128 http_port 60088 # Uncomment and adjust the following to add a disk cache directory. cache_dir ufs /var/spool/squid 200 16 256 cache_mem 128 MB # Leave coredumps in the first cache dir coredump_dir /var/spool/squid # Add any of your own refresh_pattern entries above these. refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320 forwarded_for off request_header_access Referer deny all request_header_access X-FORWARDED-FOR deny all request_header_access Via deny all request_header_access Cache-Control deny all visible_hostname test.test.co.jp cache_access_log /var/log/squid/access.log cache_log /var/log/squid/cache.log cache_store_log /var/log/squid/store.log ------------
