[squid-users] howto forward to squid proxy

Hello
First i want say sorry for bad english :(
Here mine situation

I work in huge gonoverment netowk. Mine network uses proxy to acces
internet. Shame that proxy not transparent... so i must every time
tipe setting in every PC. Thats anoying. SO i want to change
situation.

I made a bit stupid gateway PC (debian). With single network adapter.
Mess a bit with IP tables. And simple gateway working.
network Cnfig:
[CODE]
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
allow-hotplug eth0
#iface eth0 inet dhcp
iface eth0 inet static
address 10.0.8.226
netmask 255.255.255.0
gateway 10.0.8.1
[/CODE]
iptables Config:
[CODE]
###Flush iptables configurations
iptables -F
iptables -X
iptables -t nat -F
iptables -t nat -X
iptables -t mangle -F
iptables -t mangle -X
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT

###Enable IP forwarding
echo 1 > /proc/sys/net/ipv4/ip_forward

###Enable ip masquerading
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
[/CODE]
And all seemes working.. i can browse sies (with proxie esttings).

So now i want with that Gateway make proxie transparent. So i'm
tryeing to forward 80 port to proxie.
Config:
[CODE]
###Flush iptables configurations
iptables -F
iptables -X
iptables -t nat -F
iptables -t nat -X
iptables -t mangle -F
iptables -t mangle -X
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT

###Enable IP forwarding
echo 1 > /proc/sys/net/ipv4/ip_forward

###Enable ip masquerading
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

###bandau forwardint 80 porta
iptables -A FORWARD -j ACCEPT
iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT
--to-destination 212.59.6.119:80
[/CODE]

Well it seems forwarding working... but i try to get page (for example
www.inuxforums.org)... i get from proxy error
[CODE]

But if i put proxie setting in browser (212.59.6.119:80) all again works fine.

So i want to advice what i'm doing wrong..

P.s. Auto proxie seetings not possible. And i hawe a lot of
notebooks.. so they every time need to change setting.. and thats bad
:(
