Hi: I am working in a scope plenty of MS windows, we have the oportunity to start to replace some of them by linux.
We need to solve this problem : PC 1 default MS win --------- gw ----------- gateway PC1 | | | Linux BOX | | ip public --------------- INTERNET in the linux box we have a proxy squid , it authenticate against PDC ( MS win NT) , everything works OK (with samba , winbindd ) . An user from PC1 can acced to internet using Linux as a proxy and authenticating itsel against PDC. But the user in PC1 wants to use MSN and netmeeting :-) I tryed to configure netmeeting to use HTTP proxy pointing to Linux Box and in the linux box put /sbin/iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 1863 -j REDIRECT --to-port 3128 when the user tun MSN , it ask userid and password (this does not happen when it uses a browser because it is authenticated directly against the PDC) , when the user introduce de userid and password , the squid give tcp denied , and the user can not connect. Surely I am doing some mistake , can anybody help me ? thanks dl Argentina
