ftp smtp&pop with squid and iptables

[ssilayaraja]

I have configured squid proxy on centos 5 in my office with two network card
1) 180.192.6.2-eth0 connected with LAN
2) 192.168.0.1-eth1 connected with ADSL

i have configured my cent so box as a router by editing /etc/sysctl.conf

and i didnot configured any iptables settings, eventhough our office staff can brosw all sites using squid proxy.

but what my problem is

1. our employes could not connect ftp server to outside network
2. our employes could get our ISP mail

we are using outlook express to connect our isp pop3 server


kindly give me your valuable ideas

you can open your ftp port 20,21 for the operation.

See if your squid acl blocking ftp connection:-

acl block_ftp port 21
http_access deny block_ftp

i checked it is not blocking

BTW, the user can't ftp to outside using internet browser?

did u try to ftp using any ftp client instead?
