Hello!
I’m planning the following network architecture:
WAN <–> NethServer NIC red with static IPv4 <–> Nethserver NIC green 192.168.100.0/24
WAN <–> Router with Dynamic DNS <–> LAN 192.168.178.0/24
Question:
How must I configure another NethServer NIC to establish connection to LAN 192.168.178.0/24?
Red, green, blue or orange?
For me green looks to be most adequate… can you confirm?

Hi @cmonty !
I understand that you have two WAN connections in the same location?
Why do you want to use two NS?
Can you be more specific?
Anyway, it depends by how do you want to use the NS on the second connection.
If you use your router as Firewall/UTM, you can choose GREEN.
If you use your router only for NAT (any to any) and you want to use NS as Firewall/UTM, you must choose RED and the others NICs that are on NS, GREEN (LAN), ORANGE (DMZ) or BLUE (WLAN Guest, generally).
Kind regards,
Gabriel
My ISP offers static IPv4 address.
I was thinking to assign NethServer red to this static IPv4 address bypassing the router.
This means the router offers function “bridge” and hereby acts as modem only.
In the end I will have direct internet access with NethServer over static IPv4 + internet access with router using dynamic public IP.
The network behind the router is a private LAN equal to the green network of NethServer.
Question:
How can I connect these two networks?
So, you want to connect 192.168.100.0/24 with 192.168.178.0/24?
Something like this?
I read your posts again and I’m a bit confused.
Do you have two ISPs? One (WAN 1) who gives you static public IP address and another (WAN 2) who gives you dynamic public IP address (PPPoE, DHCP)?
I’m sorry for causing confusion.
Technically there’s only 1 ISP, and the contract includes 1 static IPv4.
This static IPv4 is bound to a MAC, and I need to maintain this with the ISP directly.
In theory I can maintain the MAC of router or any other MAC.
I decided to maintain the red NIC of NethServer, connect this NIC with the router and bridge the relevant port internally in the router.
Hereby the router is bypassed by any traffic going through this port and only acts as a modem.
In this picture the host would be represented by NethServer.
And there’s another LAN provided by NethServer green NIC -> 192.168.100.0/24
If you think this makes sense, there’s another question.
NethServer is running on a VM (KVM) with 3 virtual NICs.
Should I maintain the MAC of virtual NIC (red) or the MAC of physical NIC bound to virtual NIC?

I don’t exactly understand your picture. Why do you create 2 devices where you have only 1 device? The Fritzbox is a modem/router, but when you (or your ISP) put it in bridge mode, the router function will be disabled and the IP address received from the modem will be passed on to the first device connected after the Fritzbox (= your NS)
Look at my picture from here: http://community.nethserver.org/uploads/db8506/original/1X/3757dc0597ed5a467ee84c18421ef91a91d8b9d1.png

It is what do you need.
As @robb said:
You will connect NS RED NIC to your modem (PPPoE in my picture).
