Re: [squid-users] Slightly OT: Configuring a router for Squid.

What I understood:

1. You are using the same Wireless link for both: your office and your
guests <--- if so, that's a bad idea.
2. You have no Domain Controller on your network.
3. You have no DNS on your network.
4. You need to implement access restrictions for you internal network,
but not for you guests (so, you have an "open wireless AP" that is
used for your customers).

I would suggest:

Internet ---- DLink ADSL router ------ Linux box with 2 network cards
------- Your internal network ------ maybe a second wireless ap.

This way, you will allow your guests to access Internet (direct), but
not to your internal network (which is always a bad idea: virus and
stuff). Also, you will be able to enforce access restrictions for
your internal network. The "second wireless ap" is needed only if you
need wireless access to your internal network, and that one should, at
least, have WPA2-PSK with a long key, and that key should be changed
at least once every two months, and ideally should be configured with

In the Linux box you put:

+ Squid.
+ Linux firewall.
+ Internal DNS
+ Web server for wpad.

Maybe, other interesting services for your internal network, but that
would be really off-topic. This is not the only option, there are
several others, but I find this one more "secure", because it
separates your guests from your internal network.

I hope this helps,
