Squid 2.7.STABLE3 transparent proxy + NTLM

[blastik]

Hello all,


I'm trying to setup a transparent proxy with squid and NTLM authentication. It looks like everything its fine but i cannot find the error.
squid.conf as follows:



#basic config
http_port 8080 transparent
visible_hostname *********
cache_mgr *********

#ntlm auth
auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp
auth_param ntlm children 10
#auth_param ntlm max_challenge_reuses 0
#auth_param ntlm max_challenge_lifetime 2 minutes
#auth_param ntlm use_ntlm_negotiate off
auth_param basic program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic
auth_param basic children 5
auth_param basic realm Domain Proxy Server
auth_param basic credentialsttl 2 hours
auth_param basic casesensitive off
authenticate_cache_garbage_interval 10 seconds

# Credentials past their TTL are removed from memory
authenticate_ttl 0 seconds

#accept only authenticated users
acl lcl src 192.168.1.0/24
acl auth proxy_auth REQUIRED
http_access allow lcl auth
http_access deny all
miss_access allow all
icp_access deny all


iptables as follows:



iptables -t nat -A PREROUTING -s 192.168.1.202 (squidip) -p tcp --dport 80 -j ACCEPT
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080
iptables -t nat -A POSTROUTING -j MASQUERADE


I have only one interface (eth0):

ip fija: 192.168.1.202
dns: 192.168.1.2 / 192.168.1.12
gw: 192.168.1.9 (router's ip)

When i try to access to google for example i get this on the access.log file:



TCP_DENIED/403 1518 GET http://www.google.com/ - NONE/- text/html


Thanks in advance!
