Hello.
here is the network diagram.
Code:
<INTERNET>
|
<ISP - MODEM --- ETHERNET + WIFI ROUTER> wan side Dynamic IP, and wifi is disabled.
| |
| | 192.168.2.0/24
| |
| +------------> subnet 1
|
|
<NETGEAR - ROUTER 1> ETHERNET - NO WIFI HARDWARE
| |
| | 192.168.3.0/24
| |
| +------------> subnet 2
|
|
<DD-WRT NETGEAR - ROUTER 2> ETHERNET + WIFI ROUTER. Run as DHCP server and dns server.
|
| 192.168.4.0/24
|
+-------> subnet 3
On subnet 3, I am planning to configure :
1) a Postfix mailserver sending mail using my ISP SMTP Server
2) a local web server
I would like to have a name for the router itself, for the mailserver, and for the webserver.
here the part of the configuration for that :
Code:
#
# DOMAIN NAME : my_domain.nwk
#
domain=my_domain.nwk
local=/my_domain.nwk/
local=/localdomain/my_domain.nwk/
address=/my_domain.nwk/192.168.4.230
#
# MAIL SERVER ( 192.168.4.80 is computer address running postfix mailserver. Address different than web server )
#
address=/mailsrv.my_domain.nwk/192.168.4.80
ptr-record=80.4.168.192.in-addr.arpa,mailsrv.my_domain.nwk
mx-host=my_domain.nwk,mailsrv.my_domain.nwk,10
mx-target=mailsrv.my_domain.nwk
localmx
#
# WEB SERVER ( 192.168.4.230 is router address . Address different than mail server )
#
address=/www.my_web.nwk/192.168.4.230
ptr-record=230.4.168.192.in-addr.arpa,www.my_web.nwk
DD-WRT router act as dhcp server and dns server.
I would like :
nmap return "my_router" and "192.168.4.230" and mac address and not "www.my_web.nwk" and "192.168.4.230"
Is it correct ?
Are there any redundancy?
Are there any contradictions?
Any comment is welcome. _________________ Netgear R6300v2 DD-WRT v3.0-r47495 std (09/28/21) - Linux Opensuse Leap 15.2 - Win 10

instead of 3 NAT's you can put ISP modem/router in bridge mode and have only DD-WRT router with as many subnets you want...
what's the reason you need this Netgear in the middle...???
there is an option to run your DD-WRT in WAP mode
but this is not the case you want..i guess _________________ Atheros

As my above questions show , routers are not one of my favorite things.
The first router is an ISP router. If I run into technical problems, I am sure to be alone. So I don't want to change any things that is not accessible from the vendor windows management. Secondly the first subnet goes also to the home's caretaker and the TV port for the TV decoder must be connected to the port #4 of ISP's router. So modifying the router could prevent him from receiving TV at home.
One reason I keep router #2 is that it is here, and I have not really enough time to think to another physical/logical architecture. I have a small project under Linux with a mail server and a web server without a real domain name. So I started with that configuration.
So based on that configuration, is the config correct, are there any redundancy, are there any contradictions?
Thank you for helping. _________________ Netgear R6300v2 DD-WRT v3.0-r47495 std (09/28/21) - Linux Opensuse Leap 15.2 - Win 10
