i have got little more understanding in clearos.
my problem was exactly same.
i have some internel web servers in my environment.
i am using 1-1 NAT to map the public ip of my isp with the local ip.
when i disable all the NATing, my network become damn fast.
i went through 1-1 NAT and port forwarding related topics in our forums.
As i understand Tim's 1st reply,
1-1 NAT is the suitable one for my atmosphere.because i am using many external ips to bind with different local ips.
i want reconfigure my NATing stuffs.
my question is simple any novel little experienced clearos users can answer.
Network ==========>Firewall==========>1-1NAT windows of the webconfig has two sections.
1.configure 1-1 NAT
2.Configure 1-1 NAT Port
in the 1st section, if i map a local ip to public ip, will all the inbound traffic with different ports to the particular machine is allowed? or only 80
in the second section,last field in the name of PORT denotes port range for particluar ip or from port to port.
right now i configured by assuming it as from port and to port..
