[FW-1] Problems NATing
I currently have a test setup running CP4.1sp5 on Win2KAdvancedServer. The
outside NIC is DHCP which gets a DHCP address from an ISP (this usually
stays the same so my FW object reflects the actual IP that is always
renewed); this is my only public address. Meanwhile I have my internal NIC
on a private address attached to a hub which is then connected to multiple
PC's all on the same network segment. I need to set up the multiple PC's on
that network segment to initiate and accept internet traffic. Do I need one
more public address to NAT the private network segment to or is there a way
I can set it up to use the one public address I currently have available?
Right now I am setup to NAT one server to the 1 public address but I have
problems connecting to the outside world via HTTP; if I run my anti-virus
updates for example, it goes out checked for an update and downloads the
necessary updates, but when it comes to HTTP, it doesn't seem to complete
the 3-way handshake. I have also run into problems getting SMTP through: I
check my mail on the private network segment, I can see traffic passing
through my FW logs, and I get 20 mail messages but then get a message saying
"lost connection"; when I re-retrieve the mail again, I get all the same
messages downloaded again; so some weird things are going on which is
leading me to think having only one valid addresses, which is being used by
my FW's external address is causing some "behind-the-scenes" headaches. Any
help, words of wisdom would be greatly appreciated, TIA!
