hi everyone…how are you???
i just want to know how to configure ubuntu squid server in mikrotik…
i have running squid proxy server…and when i put my squid’s ip to my browser proxy setting then it works fine…

My quistion is how to configure proxy server to mikrotik as parent proxy..

squid ip is 192.121.122.3
port 3128

mikrotik network address 192.121.122.1
dns1= 192.168.0.1
dns2= 192.168.2.1

please anybody help me…

please check http://wiki.mikrotik.com/wiki/Manual:IP/Proxy

details on how to set up parent proxy. You can disable caching on router off, so you do not cache on nand.

you could also add a nat rule

     chain=dstnat action=dst-nat to-addresses=192.121.122.3 to-ports=3128 protocol=tcp in-interface=ether3 dst-port=80

make sure you change the interface to the network that you want to use the proxy. Also this wont work if squid is on the same subnet as the clients you wish to use it.

thanks.but one more question..i m using ether1 as WAN..and ether2 as LAN.so where should i connect my squid…directly ether3 or
Ether2=switch=squid??
Plz help.

It’s easiest if you attach the Squid box to ether3 on a completely separate network.

that is what http://google.com is for. Without seeing your config file i dont really know but I think that you dont have squid set to trasparent mode.
you probably have a line that looks like:

http_port 3128

It needs to look like:

http_port 3128 transparent
