Squid use eth1 outgoing ip change

squid

I've set up squid as an http proxy and I've multi nic cards, by default it uses eth1 ip for outgoing; I want it to use eth1:1 ip for outgoing. Any clue?

Best Answer

Correct option is tcp_outgoing_address.

tcp_outgoing_address 123.123.123.123

Of course, replace 123.123.123.123 with your ip address assigned to eth1:1

Multple IP routing on Squid Proxy

Found a way of doing it. In the squid config I setup 4 http_port values with an acl for each port:

acl portA myport 8080
acl portB myport 8081
acl portC myport 8082
acl portD myport 8083
http_port 8080
http_port 8081
http_port 8082
http_port 8083

and then I redirect the outgoing ip address according to the port it came in on:

tcp_outgoing_address 192.123.0.10 portA
tcp_outgoing_address 192.123.0.11 portB
tcp_outgoing_address 192.123.0.12 portC
tcp_outgoing_address 192.123.0.13 portD

Then before I make a request to a certian web page I change the port in the browser proxy settings and the the IP address they see changes.

Only issue is that it seems to have a cache on it. I need to wait a few minutes after I change the proxy port before it reflects the new ip address.

How to force Squid Proxy to use a specific gateway for internet access

Original

From a command prompt:

sudo route add default gw i.p.add.ress eth1

Then, in /etc/network/interfaces, add this line:

up route add default gw i.p.add.ress eth1

Of course, replacing i.p.add.ress with the gateway's IP in both lines.

Edit for new question

If you need to delete a route, just change "add" to "del". Example:

(command) sudo route del default gw 128.0.x.x eth0
(/etc/network/interfaces) up route del default gw 128.0.x.x eth0

You can set a static route for the branch office through the route command as well

route add -net (network_id/prefix) GW (gateway) (interface)
