Why port 8080 instead of 3128?
Also, is this the same box which Squid is running on? I ask because of the use of DNAT instead of REDIRECT.
I had forgotten about DG. What Tarantella version are you using? According to their FAQ, you need at least version 3.1 in order to use a proxy. Not sure what else to tell you, at this point I'm not even sure Squid is the problem here. I would suggest you take a step back and start troubleshooting by trying with a direct connection, then trying with a SNAT connection, then adding Squid (non-transparent), then adding Squid (transparent) then DansGuardian. As soon as you hit a step where the functionality breaks, then you know where to focus your energy. I'm sorry I can't be of any more use to you at this moment.
