2nd ethernet port for backup data to other readynas?
Hi all,
I can't get the following setup to work:
I have read: https://community.netgear.com/t5/Using-your-ReadyNAS-in-Business/dedicating-2nd-ethernet-port-for-backups-how/td-p/957428, but it...
I'm not completely clear on your "correction", but I think you have this:
Pro4:
Ethernet port 1: Static 192.168.2.91 / Gateway 192.168.2.254
Ethernet port 2: Static 192.168.2.89 / Gateway 192.168.2.254
NV+:
Ethernet port: Static 192.168.2.90 / Gateway 192.168.2.254
When what you need is this, assuming your home network is 192.168.2.xxx::
Pro4:
Ethernet port 1: Static 192.168.2.91 / Gateway 192.168.2.254
Ethernet port 2: Static 192.168.3.89 / Gateway 192.168.3.254
NV+:
Ethernet port: Static 192.168.3.90 / Gateway 192.168.3.254
Of course, neither the Pro4 port 2 nor the NV+ can actually reach 192.168.3.254. Besides no internet access, I don't know what consequences that will have, if any.
BTW, you missed another important item in the post you referenced. It is for two NASes that each have two Ethernet ports, so admin and internet connections are still available through the other port on each.

People have deliberately misconfigured gateway addresses before (to intentionally block internet access, but continue local administrative access). so I believe that will work.
Some consequences are
- Inaccurate time on the NV+, since it can't sync to NTP. The amount of inaccuracy will increase over time. If the RTC backup battery in the NV+ is dead (likely given the age of the NAS) then the clock will be completely wrong when the NAS is restarted after being disconnected from power.
- Loss of email alerts
- No ability to use hostnames in backup jobs.
Eliminating local administrative access for the NV+ (which this setup also does) is of course a bad idea, as I tried to explain above.
