ubuntu-12.04

I have a server with ubuntu 12:04 operating system, which runs as a proxy cache server lusca and DansGuardian as well as internet content filter.

With the following composition: the client browser -> lusca -> DansGuardian -> internet. And all this running only on one machine only, the following is a partial configuration on my server lusca:

http_port 3128 transparent

cache_peer 192.168.0.1 parent 8080 0 no-query no-digest no-netdb-exchange default

which is also only found on the DansGuardian default settings namely:

filterip="blank" filterport=8080 proxyip=192.168.0.1 proxyport=3128

The question is:

Can all goes well? By simply relying on one machine only?
What causes the "WARNING: Forwarding loop detected for:"? is not problematic if we leave?
How to solve "WARNING: Forwarding loop detected for:" found in / var / log / lusca / cache.log

Thank you.
