Hi Amos,

Here is the squid.conf file:

acl localnet src 172.16.0.0/16

And this is an extract of the log:

As you can see, always is going direct, but when going to idp.fecyt.es should be going through the peer, as the file UPF_LIST.txt has:

https://idp.fecyt.es
https://idp.fecyt.es/
https://idp.fecyt.es/*
 
among other lines.

Okay then the issue is something else, those lines in isolation are correct for allowing traffic to use that peer, but there are many other things that may make other routes either required or preferred.

So what is the rest of your squid.conf and can you provide a sample of the access.log for the traffic going wrong?
