I don't know. I'll admit that I don't fully understand what I'm doing
here, which I apologise for, but I'm trying to learn.

All I want to do is retain a packet's mark from its arrival into Squid,
onto its transmission to the client. Something like this:


ppp0 -> PREROUTING -> Squid -> POSTROUTING -> eth0

            ^^                      ^^
         Set Mark               Read mark


If this isn't possible then please tell me.

Thanks,

Andy
