Thanks Stuart. I set the default route on my host and I can see it in
my route table but I'm still not able to send out pings. Is there a
way I can verify that the packets are making it to PF? Does the order

However, you can filter statelessly on the internal interface (the

what i want is impossible, but i hope, someone might have an idea...
I want to use ftp-proxy for outgoing
Wait, the squid server is on a separate host, on the $int_if side of the
firewall (the same side the clients are on)?
Then transparent proxying would require reflection, and doesn't work, see

If squid is seeing TCP_MISS errors, that probably means
