i have addes a pix 506 to my network and am having problems. the network is a win2k domain with 2 windows 2003 servers amd a win2k server. the windows 2000 servers can access the internet but nothing else can. its like a DNS error but i cant figure it out. when i put back my old firewall/router the problem goes away, help...... i have given the pix standard PAT/NAT config.
