I configured my PIX Firewall and opened all the TCP ports, I found that i
can ping yahoo or cisco by ip address but not with name i.e ping cisco.com
doesn't worked, then I opened all the UDP Ports also and my Surfing started
also I was been able to PING by name.
I just want to allow port 80 (HTTP), FTP , SMTP access to my users.
Which all Ports do I need to Open??????
DO I Need to open a port for DNS Name Resolution ?????
I am using DNS Server of ISP as I don't have resources to set-up my own DNS.
Please Help
