Hi All,
So my electricity bill is through the roof and I need to pair down
some equipment.
I have a CentOS 6.5 Server (a few TB, 32gb RAM) running some simple
web stuff and Zimbra. I have 5 static IP's from Comcast. I am
considering giving this server a public IP and plugging it directly
into my cable modem. This box can handle everything with room for me
to do more.
Doing this would allow me to power down my pfSense box and
additional servers by consolidating onto this single box.
I have the firewall on on the server and only allowing the few ports
I need.
I dont run ssh on 22
An additional consideration on Comcast's network is IPv6. Comcast will
assign your routing device a /64 netblock in many, perhaps most,
markets.
If, after being connected directly to your Comcast connection and
having its network service restarted, your CentOS box still has an
fe80::/64 address, you have no worries (yet). If you're on a 2601::/64
(or other 2xxx::/64) network, then you're accessible via IPv6.
So make sure that in addition to iptables, you brush up on ip6tables
as well.
