Wait, where is squid coming in at this level - pop3/imap? This has nothing "possibly" to do with proxy whether transparent or "opaque :)"

Server is out in the world and not in your LAN right?

Are you having the linux box as your gateway/firewall?

Whats the output of sysctl -p

paste below and a sketch pointer here if you need help otherwise we are just guessing what you want to do.

sysctl -p

iptables -t filter -L -n

and

iptables -t nat -L -n


If you got 2 network cards, think rule should be FORWARD and not just INPUT on the iptables. If its not the gateway to the LAN, this doesn't matter anyway.


Kind Regards,
Wilson./

I have enabled the IP forwarding but still it can't work. I have also tried the following rules but still stuck..
iptables -A INPUT -p tcp --destination-port 25 -j ACCEPT
iptables -A INPUT -p tcp --destination-port 110 -j ACCEPT

Kindly let me know if squid has to be transparent and also if it has to be the default gateway for that case.

Hi Skunks,

I am unable to allow MS Office Outlook to access email through POP3 or IMAP
protocol in our office. Our squid proxy is not configured as transparent
proxy and the mail server is present at a public domain. I have tried to
create some iptables rules but Still it doesn't work. Must the proxy be
transparent and how should the iptables rules look like?!

Could any body guide/help me out in this regard.

Thanks in advance.

Remember to allow port forward:

Better still if you could paste your iptables rule we would help better - i
think.

/etc/sysctl.conf

edit line below and set 1

net.ipv4.ip_forward=1

Then

sysctl -p

OR

echo 1 >> /proc/sys/net/ipv4/ip_forward   < if ipv4, navigate for ipv6.

Best if you reboot at this point.





Kind Regards,
Wilson./
