Squid on my QNAP NAS.

[VirtualLarry]

I think I have that installed on my oldest NAS. I never bothered to config any of my client machines to point at the NAS for proxy settings.

However, I remember, Internet Explorer has an auto-detect proxy setting for LAN. I'm wondering, does Waterfox too?

I've had some issues the last few days, with web sites coming up with missing bits and pieces. I also just upgraded all of my NAS unit's firmware(s) just that night too.

I'm wondering, if I might "accidentally" be actually using the squid proxy, even though I haven't configured it on my client boxes, if there is some mechanism to auto-detect it on a LAN?

Does anyone know how squid works? Is my theory possible, and maybe I've unknowingly been using my squid proxy for months and months now, and never realized it? Any idea how to check?

Edit: There's a "Squid" icon on my QNAP main screen, clicking that, required authentication, and then it said that it was "enabled".

I opted to clear the cache, it took some time.

Then I reloaded this AT forum page, and... it loaded right up, no delay that I could see.

Any way to test my proxy cache theory?

Edit: I disabled it, and browsing on my client box didn't seem to change any. Squid was set for "Administrators only". Presumably I would have had to authenticate, in order to use it?

If you haven't set your browser to use a proxy, you can be pretty sure it's not using a proxy.

IIRC, squid has a transparent proxy mode. If turned on, all http request from clients will be forwarded to squid proxy server. No configuration change needed for client's browsers.

At least that's the case with pfSense. Don't know if QNAP's squid has that option somewhere? Or maybe it's built-in and turned on already?

But QNAP is an NAS, did you setup DHCP so client PCs use it as gateway/router? If not and you have a router serving DHCP addresses to clients, there is no way the clients will use QNAP's squid proxy automatically.

Unless the NAS is also your DHCP device it is very unlikely that squid is in transparent mode and running without any client configuration.

You can do this easily on pfsense though, very seamless and no client configuration required.

DHCP has nothing to do with transparent mode, transparent should only work if the NAS is sitting between your clients and internet connection.

DHCP does matter if it is configured to point the gateway to the IP of the NAS and squid is in transparent mode.
