Im definitely NOT a network manager, but sometimes I have to....

I sit on a SuSE Enterprise Desktop 10.
I am in a LAN: 10.x.y.z/
I have to go through the proxy: 64.a.b.c/ which is in the next town to reach the internet.

In the squid.conf file, I read:
-----the line "acl allowed_hosts src should be replaced with your own".

Can anyone tell me where I can find these parameters??
Thank you in advance...
