Hi All,
Sorry, I am still confused about implementing a firewall without
having my ISP static route all of my traffic to my public IP's to a
single public IP.
So before when I have done this for work all traffic has been
statically routed.
Now I have a comcast modem and it is 'pass through' so traffic for all
my 13 IP's is allowed and I have to decide what to do.
So I am looking at Vyatta or UnTangle. I have a machine with 3 NIC'e
in it. I think one would be In, DMZ and last private.
What happens? I have one cable from my comcast gateway to my firewalls
NIC, but how does it answer for all IP's that I have so i can evaluate
the request incoming to a rule set and decide if allowed or denied?
I am missing something fundamental! Can anyone help this click in my
head? Without statically routing my traffic I dont get it.
Say a request comes to my webserver 172.13.167.xxx on port 80, but my
firewall's IP for the card is 172.13.167.zzz how does it answer for
172.13.167.xxx?
