Hello,
i have installed a ubuntu 12.04 with squid 3.3.5 as intercept(transparent proxy) + iptables.
now i can visit websites over http but not https! i will paste my config below
here is my network configuration:
auto lo
iface lo inet loopback
# The primary network interface
auto eth0//INTERNET
iface eth0 inet static
address 192.168.4.96
netmask 255.255.255.0
broadcast 192.168.4.255
gateway 192.168.4.1
dns-nameservers 192.168.4.100
auto eth1//LOCAL
iface eth1 inet static
address 192.168.4.97
netmask 255.255.255.0
broadcast 192.168.4.255
So im about to receive from eth1 and send to eth0!
In client side Default Gateway = ip address of eth0 on squid server(192.168.4.96)
squid.conf:
#
# Recommended minimum configuration:
#
# 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 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 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:
#
# 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
# Only allow cachemgr access from localhost
http_access allow localhost manager
http_access deny manager
# 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
always_direct allow all
ssl_bump allow all
# the following two options are unsafe and not always necessary:
sslproxy_cert_error allow all
sslproxy_flags DONT_VERIFY_PEER
# And finally deny all other access to this proxy
http_access deny all
# Squid normally listens to port 3128
#http_port 3128 intercept
http_port 3128 intercept ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=4MB cert=/usr/local/squid/ssl_cert/myCA.pem
# Uncomment and adjust the following to add a disk cache directory.
#cache_dir ufs /usr/local/squid/var/cache/squid 100 16 256
# Leave coredumps in the first cache dir
coredump_dir /usr/local/squid/var/cache/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
in /etc/sysctl.conf ipforwading is enabled.
and for iptables:
iptables -t nat -A PREROUTING -i eth1 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 3128
iptables -t nat -A PREROUTING -i eth0 -p tcp -m tcp --dport 80 -j DNAT --to-destination 192.168.4.96:3128
i added these two rules work well for http, i tried many rules for https non them works!
Please check squid configuration if its okay please give me the firewall rule
thank you very much
