Hi folks,
I have a little bandwidth problem. My customer's network is simple like
this: internet ---> squid 2.6 StabLe 5 (trasparent mode) ----> lan
172.16.0.0/16
Now, the problem is that when I redirect the 80 port to 8080 (squid) all
the clients' connection slow down (from 250 Kbyte/s to 20/30 kbyte/s),
and when I disable the iptables rule all returns fast.
How did you measure the slowdown is speed? And what is your actual
bandwidth pipe?
How can I solve this?
Squid.conf
http_port 8080 transparent
icp_port 0
htcp_port 0
cache_access_log /var/log/squid/access.log
cache_log /var/log/squid/cache.log
cache_store_log /var/log/squid/store.log
emulate_httpd_log on
mime_table /etc/squid/mime.conf
pid_filename /var/run/squid.pid
dns_nameservers 213.140.2.12 208.67.222.222 193.205.245.66
acl all src 0.0.0.0/0.0.0.0
http_access allow all
iptables rules
$IPTABLES -t nat -A PREROUTING -p tcp --dport 80 -s 172.16.0.0/16 -j
REDIRECT --to-port 8080
$IPTABLES -t nat -A POSTROUTING -s 172.16.0.0/16 -j SNAT --to-source
192.168.1.2
How many network interfaces does your Squid box have? So this box
performs NAT and Proxy service simultaneously?
Maybe you have large ACLs filtering on your squid.conf? What is the
output of "squidclient mgr:info"?
Thanking you...
Thank you in advance
Matteo
