Hola a todos
Favor si alguien sabe como solucionar la siguiente incidencia, configure un proxy con las opciones basicas funciona bien carga todas las paginas a excepción de las Https no lo hice proxy transparente por este inconveniente, pero resulta que tengo este problema, favor indicarme si debo configurar algo adicional el squid, agregar reglas con el iptables, a continuacion detallo lo unico que configure en el squid y en iptables les detallo a continuación

#
# 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
# Comento las 5 siguientes lineas
#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 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:
#
# Se agrego las siguientes lineas
#acl ippermitidas src "/etc/squid/listas/ippermitidas"
acl macpermitidas arp "/etc/squid/listas/macpermitidas"

# 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
# comento la linea siguiente
#http_access allow localnet
http_access allow localhost
#http_access allow ippermitidas
http_access allow macpermitidas

# And finally deny all other access to this proxy
http_access deny all

# Squid normally listens to port 3128
# Comento la siguiente linea y agrego 2 lineas
#http_port 3128
http_port 192.168.0.254:3128
http_port 192.168.0.254:8080

# We recommend you to use at least the following line.
hierarchy_stoplist cgi-bin ?

# Uncomment and adjust the following to add a disk cache directory.
#cache_dir ufs /var/spool/squid 100 16 256
# Agrego la siguiente linea
cache_dir aufs /var/spool/squid 2048 16 256

# 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
# se agrega las siguientes lineas
maximum_object_size 48 MB
cache_swap_low 90
cache_swap_high 95
visible_hostname proxysrv

Y la unica regla que puse en el Iptables es
iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -o eth1 -j MASQUERADE
