[squid-users] cisco wccp configuration question

here is layout
squid proxy on lan 0 running in transparent mode
cisco 3640 connecting lan 0 and lan 1
lan 0 users browse web using ip of fa1/0 on cisco as default gw and requests
hit the squid proxy via wccp
lan 1 users browse using ip of e0/0 as gateway and and requests get sent to
squid via wccp
now i have a remote site connected via serial 0/0 (t1) but when they try to
browse web they dont get to the squid proxy - they get nowhere
here is cisco config

end

192.168.1.1 is core router where internet connections terminate
squid proxy is 192.168.1.6

now at the remote site, they are running a firewall and another squid proxy
that is also transparent (users use squid as gateway and then gateway uses
openbsd firewall to get to their router which connects to t1)

it seems like this should just work, but the remote t1 users cant browse and
can ftp/smtp/pop etc so I was just wondering if there is something i need to
add to there serial interface config to get this working.
