Hi, My friend has a sharepoint (don't know what it is) server in her DMZ at 10.10.10.3. She can access that server from outside world by giving its public IP in browser. She cannot access it via her squid proxy inside the LAN. But when she removes proxy settings and gives, iptables -I FORWARD -s 192.168.10.7 -j ACCEPT she can access it. When I say access here it means that in all cases she can see IIS page but it is giving authorization failed from inside LAN. When she removes proxy settings and gives iptables rule above she is presented with a username-password box which is not seen via squid internally. Strangely if I am on the squid/gateway/firewall machine and still using proxy I can see the authorization box. Can someone give us both some hints to proceed? With warm regards, -Payal
