Thanks ahead of time...
I have a Win2003 web server with multiple sites (not using host
headers) running in a data center. As of now I only have a software
firewall running on it. Want to add a hardware appliance but am
stumped on what I need to look for. I am confused about what it takes
to forward multiple (not consecutive) external IPs in our range
through to multiple internal addresses. I know the basics of hardware
firewalls but am not sure what to look for that would fit this need. I
definitely know the cheaper firewalls don't support this. I've looked
over what sonicwall has to offer but am not sure which firewall would
be best for this. I don't want to do anytning too fancy, just block
the junk packets before they get to the machine and lock down all but
thenecessary ports. Each IP now has at least http/https/smtp/pop
running on them. Also, what exactly is the interface in the firewall's
admin that would allow this? Is it 1-1 NAT? Thx, Roy J
