Yet another squid and pop3 questions. I know that squid is a http proxy and can not handle pop3 and smtp. But how can I get my local clients from my network to access their email from the isp via outlook?
My network looks like this Internet<----> Router<----->Linux Box (Redhat with Squid Installed) <-----> Switch<----->Internal clients

I do not want to change the configurations on my network that i currently have. I was hoping there was a way that I could bypass or forward the pop3 and smtp ports past squid? Someone had mentioned iptables but I have never used them before and am not sure if I want to play with that.
Can i just tell squid to allow anything on port 110 to flow through? Or can I tell my linux box to force port 110 to go stratight to the router?

I can access email via pop3 from the linux box.

I have read through the other threads and tried most of the suggestions without and luck (setting up sendmail, setting up a pop3 proxy). But all i want is to let the traffic to flow through without touching squid. Is it possible?

Thanks,
Ryan

Tell your linux box to ip forward port 110 and allow established,related on the reverse.

I am not overly familiar with linux. How do i go about telling my linux box to ip forward port 110 and allow established,related on the reverse.

Do you already have iptables installed and configured? You'll need to do so.

Then "iptables -A FORWARD -s $LOCALNET -p tcp --dport 110 -j ACCEPT" and "iptables -A FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT" should do it for you.

root@xxxxxx root]# iptables -A FORWARD -s $LOCALNET -p tcp --dport 110 -j ACCEPT
Bad argument `tcp'
Try `iptables -h' or 'iptables --help' for more information.

any suggestions?
Thanks for your patience and time.

Oops, sorry, should've clarified. $LOCALNET should be replaced by the local network: for example, 192.168.0.0/255.255.255.0 or similar.
