Divert Web Traffic From One SQUID Box to Another

ssd26 · 04-25-2008, 03:13 AM

Hi Everybody,

I have a squid-box with other services running on it. This squid service on this box needs to be stopped for certain other activities. The web traffic however cannot be disrupted. So i have setup another squid-box-2.
My query is how do i redirect all web traffic from squid-box to squid-box-2.

Any help is appreciated.

Thanks

well how are clients reaching that box in the first place? what other network architecture do you have? presumably you don't want to actually redirect on the box itself if it's a maintenance window you're after...?

Hi,

All the clients have their browser configured for the SQUID-BOX IP and PORT. After authentication on this box, they are able to browse.

Now since the squid services on this box are to be stopped, i need some method to divert the web traffic coming to the SQUID-BOX on port 3128 to the new SQUID-BOX-2, without the users being hassled about it.

wel you could use an iptables rule on the box, but ideally you'll have a NAT capable router between these points which would be a better way to do it... is there such a thing?

on the server itself, "iptables -t nat -A INPUT -i eth0 -p tcp --dport 3128 -j DNAT --to other-squid-box:3128" should work i think... but this isn't a nice solution if you're actively working on the box.
