I am running a NAT server to map a range of my inside IP addresses to one outside IP address. To access the web which is outside,I must go through a proxy server.
At the moment, I have to put proxy settings for each client behind the nat server on my local LAN. How can i configure the NAT server to use default proxy settings of my ISP without hacing to configure any proxy settings on all clients inside or behind the NAT server.
helps if you tell us what this nat server actually is, but unless you're using a transparent proxy under squid or equivalent then you can't do that to my knowledge. i guess you're actually looking for a transparent proxy configuration, which google can easily provide you details about.
Thank acid_kewpie .. transparent proxy is exactly what im looking for. i found this link that explains how to acoomplish this: http://www.faqs.org/docs/Linux-mini/...tProxy.html#s6
unfortunately, you cannot do authentication with transparent proxy.
So if i have authentication against my ISP's proxy, i cannot allow transparent access to my clients?
well you actually have two stages to your requirements. 1) intercept traffic and make it you *your* proxy, and 2) make your proxy go upstream to a parent proxy. not the 2nd part is where your auth comes in, and that part is *not* transparent at all, and i'm sure squid 2.6+ can handle parent authentication with basic auth at the minimum.
