proxy server iptables redirect to connect to outside card

invader44 · 10-03-2012, 10:23 AM

Hello,
I have an Ubuntu 12.04 server running Squid3 with an inside and outside card. I am testing out dd-wrt router which can redirect traffic to our proxy server. Stuck on how to allow our outside network card to allow traffic from the dd-wrt router. Need help with iptables and how to actually set this up.

Thanks

Hi, not real sure of your config, but...

port-forwarding in /etc/sysctl.conf

Quote:

#---------------------------------------------------------------
# Enable IP routing. Required if your firewall is protecting a
# network, NAT included
#---------------------------------------------------------------
net.ipv4.ip_forward = 1

If the line is not in the file, add it. 1=on, 0=off.

I use this with "transparent squid proxy" and iptables jst to save a bit of bandwidth and speedup web-page relaods.
