The request indicates that 172.16.11.1 / BazazathSquid.intranet.uplb.edu.ph has become extremely confused about what to do. Check that you: * have "via on" in both proxies * are using port 3128 for sibling communications and properly configured client requests * are using a different (secret) port for the NAT traffic from the firewall [this port ONLY needs to be known to the firewall NAT rule and squid.conf] * are NAT'ing only port 80 into the proxies * are excluding any requests sent by both proxies from the NAT rule * that rDNS for 172.16.11.1 resolves to the proxy hostname BazazathSquid... * that DNS lookup for BazazathSquid... resolves to 172.16.11.1 * vice-versa for DNS of the other sibling. Preferably all of the above can be answered with a "yes". I'll take a look through the loop detection code as to why BazazathSquid is not detecting it anyway. Amos
