I can't help any further without the numbers which you are eliding and a lot more details about the network topology configuration. PS. Squid uses modern CIDR subnet masks, not the 1970's netmask format. If the xxx mask bit does not exactly match a CIDR mask it will be mapped by dropping/0-ing the rightmost mask bits until it does.

Re: [squid-users] Access regulation with multiple outgoing IPs
Hey Amos, thank you very much for your very helpful information. Now i have an access control an SSL is fixed too but i had to add port 80 as SSL port to use the proxies as https proxy in proxifier. One more question. Now i can use the proxies from 193.xxx.xxx.x1/255.255.255.xxx. But if i want to use the proxies from a virtual machine i can not get access to them. I tried different Ips. Do you know what IPs or information i have to add to the acl on top to get the VMs working? Thank you so much!

[squid-users] Access regulation with multiple outgoing IPs
Hey guys, im trying to setup squid for windows. I have different IPs on my server and i want to assign them to VMs: VM1 --> Outgoing IP1 VM2 --> Outgoing IP2 ... So far this is working! But now i want to deny all other IPs to avoid false access. So all VMs have the same incoming IP (i think) but the outgoing IP changes by port. Can you help me to set up the access regulation and deny all unwanted adresses? 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 http_port 5.189.xxx.xx1:3129 name=3129 http_port 5.189.xxx.xx2:3130 name=3130 #VM1 acl vm3129 myportname 3129 src 213.xxx.xxx.83/24 tcp_outgoing_address 5.189.xxx.xx1 vm3129 http_access allow vm3129 #VM2 acl vm3130 myportname 3130 src 213.xxx.xxx.83/24 tcp_outgoing_address 5.189.xxx.xx2 bot3130 http_access allow vm3130 acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT # # Recommended minimum Access Permission configuration: # # Only allow cachemgr access from localhost http_access allow localhost manager 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 all # And finally deny all other access to this proxy http_access deny all # Squid normally listens to port 3128 #http_port 3128 # Uncomment the line below to enable disk caching - path format is /cygdrive/, i.e. #cache_mem 64 MB #cache_dir aufs /cygdrive/d/squid/cache 4000 16 256 # Leave coredumps in the first cache dir #coredump_dir /var/cache/squid # Add any of your own refresh_pattern entries above these. refresh_pattern ^ftp: 144020% 10080 refresh_pattern ^gopher:14400% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320 dns_nameservers xxx xxx max_filedescriptors 3200 Thank you for your help! -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Access-regulation-with-multiple-outgoing-IPs-tp4673900.html Sent from the Squid - Users mailing list archive at Nabble.com. ___ squid-users mailing list squid-users@lists.squid-cache.org http://lists.squid-cache.org/listinfo/squid-users
