Squid cache server behind a Watchguard appliance

Hi,
I have a Watchguard XTM-520 box and I'm trying to configure it to use a Squid linux as an external cache server, since watchguard does not do caching.

If I point my browser directly to the squid server
(which is behind the firewall) I'm able to browse ok.
The firebox has a setting for the http proxy that
allows you to point all outgoing http requests to a
proxy caching server (Use Webcache Server). If I plug the squid IP address
in here, browsing stops working. The browsers hang
for a while at the site contacted, waiting for reply.
Finally the request times out.

Can anyone please help me to find out why this config is not working?

Thanks,

I'm a WatchGuard certified partner. I think you need to ask the WatchGuard support experts this question. The problem may be an incompability in the redirection.

Hi,
If I understand correctly you have some net-design like this:

PC - Watchguard - Squid - RouterInternet

The trouble could be routing-traffic from squid-box to wathguard what OS you use for Squid?

Hi,
Asumming you Network Topology is like a ask before...

You need to be shure that can reach your networks by running traceroute from your linux box to your inside LAN and to internet.
Then perhaps validate a fix iptables o rounting rules on your linux, at least check squid config ACL.
Also check the logs to see whats goin on.

This is not the right solution, in general, Watchguard HTTP-PROXY only can handle WEB-CACHE SERVER only when the rule is HTTP-PROXY rule and not part of TCP-UDP-PROXY rule. The most important is that your squid need full access (preferred in different VLAN, without direct access at your local LAN). with this you will warranty that will work great.

You can use THUNDER CACHE or RAPTOR CACHE that include really good combination of cache-proxy that help to speed up your network with new WEB 2.0 technologies (facebook, youtube, googlevideo, etc...)
