Did you follow the steps outlined in
http://www.sanog.org/resources/sanog4-devdas-transproxy.pdf ? BTW, I've
never seen this document before, but looks interesting for sure.
Please note that the Squid patch for tproxy support mentioned on the
page above is completely independent from BalaBit and the authors of the
tproxy patch, and was kindly contributed by Gianni Tedesco and James
MacLean. I'm not really sure, but I'd say that in your case bind() fails
because you did not have any interfaces configured with 10.1.1.100. Try
creating a dummy interface (dummy0), and adding the address 10.1.1.100
to that interface.

I must admit that I don't really know Squid, so probably I'm not the
right person to ask. Have you already tried the Squid documentation, or
the Squid users mailing list?
