[squid-users] Problems Settup Up a Transparent Proxy

I'm trying to set up up one SuSE 9.3 system as a gateway for another
SuSE 9.3 system. Following a recommendation I'm using the instructions
for setting up a Squid transparent proxy from the SuSE Administration
Guide, section 33.5. The gateway system has a fixed IP address of
192.168.1.52, and the second is 192.168.1.50. I successfully set up a
DHCP server and that didn't help. I'm using modem2 to connect to the
Internet.

The changes I made to squid.conf are:

http_access allow all
httpd_accel_host virtual
httpd_accel_port 80
httpd_accel_with_proxy on
httpd_accel_uses_host_header on

Changes to sysconfig/SuSEfirewall2:

FW_DEV_EXT="modem2"
FW_DEV_INT="eth0"
FW_SERVICES_EXT_TCP="www'
FW_SERVICES_INT_TCP="domain www 3128"
FW_SERVICES_INT_UCP="domain"
FW_REDIRECT_TCP="192.168.0.0/16,0/0,3128 192.168.0.0/16,0/0,21,3128
FW_REDIRECT_UDP="192.168.0.0/16,0/0,3128 192.168.0.0/16,0/0,21,3128

There is no START_FW, the firewall is started by choosing the Start
Firewall When Booting option in Yast2, Squid is started with "rcsquid
start".

Firefox on the .50 system can't find www.yahoo.com. Pinging the IP
address (e.g. Yahoo at 66.94.234.13) gets no response so it doesn't seem
to be a DNS issue.

An NMAP scan shows ports 22, 111, 631 and 3128 open on the gateway
system. /var/log/squid/access.log is empty.

Any ideas?

Thanks
Paul
