Squid with three isp

Squid with three isp

[Senthilkumar]

Hello All,

We have a gateway machine which has three upstream isp and to make 
clients use the particular isp we use advance routing based on the 
source address.  When we run squid  on the same machine to log websites 
all traffic passes through the single isp i.e. the isp which is set as 
default gateway. We need all the users to pass through squid and use 
different isp's as per source route.
Please share your views to achieve it.

Thanks
Senthil.

Hi Senthilkumar,

I suppose you should use multiple rt_tables facility based on
netfilter's marks for routing to different ISPs. And you also need
some scheme to disperse marks for squid's output connections like nth
option from iptables. Here is an example:
