I need to put a toaster server into a DMZ subnet.
The IDEA is this:
INTERNET - GW - DMZ
|
LAN
And the TOASTER server be used from LAN and FROM internet.
I need some help about questions I have about this:
1) I have my DNS server (hosting my domain) in the DMZ network and
appears to be working fine. The question is: How need I configure the
SPF (and any other DNS registers) in my domain to works fine for the
LAN and the INTERNET? I have 3 public IPs (in loadbalancing
configuration).
2) How I need to configure qmail to allow the WAN and LAN domain be
used as one domain?
3) How I need to configure qmail to allow send e-mails from my LAN
subdomains (the servers in DMZ sends e-mails to internet in the form
root@<machine>.<lan_domain>).
If you know any usefull link (or more) that allow me learn how to do this,
please, send!!
Don't know of any links....
You'll set your SPF records up for whatever public IP you're using.
There's some instructions on the wiki I believe on how to set the SPF
records up. Let me know if they are not there. As far as setting up
the rest of your DNS, that's a big order and a lot can be opinion. If
you have 3 public IPs and a load balancer, I'd list all 3 IPs in a
round-robin configuration in DNS and let the load balancer work for it's
money. Others may do it different.
Qmail will not care about the LAN/WAN. It doesn't really deal with IP
addresses in this sense; it deals with accounts. If they have an
account, they can send/receive emails. Shouldn't matter where they're
coming from.
I don't understand #3. Can you explain what you're trying to accomplish?
