I've configured three squid box with iptables, and all works fine,
squid-box1 -- squid-box2 -- squid-box3 (proxys-cache)
squid-box4 --- squid-box5 (proxys-filter with squidguard)
but in squid-box4 and box5 with iptables, I've seen in cache.log
comm_udp_sendto: FD 4, ip-dns-server, port 53: (1) Operation not permitted
2003/08/20 11:21:48| idnsSendQuery: FD 4: sendto: (1) Operation not permitted
and the connections go stopping slowly until all stop,
what does these lines mean ?, I will have to enable udp port 53 like src ?
Thanks. Emilio
