RE: [squid-users] Front page problem - Help me !!!

I don't know if this has been answered already (I don't think it has), but
here's how I worked around this problem...
 
My Squid box is the default gateway for the users on my network. I run
squid on port 8080. I have an ipchains rule that transparently redirects
all outbound HTTP traffic to port 8080. It looks like this...
 
/sbin/ipchains -A input -p tcp -s 192.168.0.0/16 -d 0.0.0.0 80 -j REDIRECT
8080
 
Using that rule alone, all the outbound HTTP traffic from my private network
(192.168.0.0) will be handed off to the Squid cache (which, incidentally,
has been configured to handle transparent proxying). However, that doesn't
fix the FrontPage problem. So in order to do that, I have to create some
ipchains rules that basically say "send all outbound HTTP traffic to Squid
UNLESS it's bound to the following addresses..." It can be done a couple of
ways. If you only have one address that your users have to connect to via
FrontPage, then you can change the above rule to look like this...
 
/sbin/ipchains -A input -p tcp -s 192.168.0.0/16 -d ! aaa.bbb.ccc.ddd 80 -j
REDIRECT 8080
 
This basically says "forward all outbound HTTP traffic to Squid EXCEPT
traffic bound to aaa.bbb.ccc.ddd (where aaa.bbb.ccc.ddd is the ip
address/FQDN of the FrontPage server)."
 
If there are multiple FrontPage servers they need to connect to, then you
can do it a different way:
 
/sbin/ipchains -A input -p tcp -s 192.168.0.0/16 -d aaa.bbb.ccc.ddd 80 -j
ACCEPT
/sbin/ipchains -A input -p tcp -s 192.168.0.0/16 -d eee.fff.ggg.hhh 80 -j
ACCEPT
/sbin/ipchains -A input -p tcp -s 192.168.0.0/16 -d iii.jjj.kkk.lll 80 -j
ACCEPT
...for each FrontPage server, then, at the end:
/sbin/ipchains -A input -p tcp -s 192.168.0.0/16 -d 0.0.0.0 80 -j REDIRECT
8080
 
The order of these rules is important; make sure you put the REDIRECT rule
last.
 
Another advantage to setting it up this way is that you don't have to make
any configuration changes on your client browsers to get them to use the
Squid cache.
