Got a spare one of these knocking around at the moment I I wanted to try and isolate a network for some testing.

 

 

 

My R7000 running Tomato allows for tagged and untagged networks to run on the same ethernet ports.

 

The nf18acv has a "Lan VLAN Setting" option but there are no details or instructions on what it can actually do. Has anyone had a play with this?

 

My ideal would be a

 

  • tagged VLAN X from R7000 -> NF18ACV port 4.
  • Normal LAN untagged R7000 -> NF18ACV port 4.
  • Norma LAN on Port 1 of NF18ACV
  • Untagged access to VLAN X on ports 2 + 3 of NF18ACV

This would allow me to use the R7000 to provide all DNS and DHCP services regardless of endpoint network. It can also handle any internetwork routing.

 

I  have a feeling my best option is to run the nf18acv as its own network with its own IP address range rather than having it run as a VLAN.

 

  • R7000 -> NF18ACV WAN Port
  • local private LAN X DHCP on NF18ACV
  • Ports 1-4 on NF18ACV on private LAN X

Damn I wish there was a ddwrt/openwrt build for the NF18ACV

 

Any thoughts that don't require additional hardware.

So I'm instead trying with the NF4V older model

 

One thought was to accept a tagged VLAN on the WAN port and then have all of my private LAN clients on the LAN ports.

 

In theory it is setup correctly, but in practise only DHCP traffic appears to be making it over the VLAN.

 

 

 

R7000 -> tagged VLAN 4  -> NF4V WAN Port VLAN ID 4 -> LAN ports -> Client

 

 

 

Client DHCP requests are being serviced by the R7000, but I can't ping the NF4v or the client.

 

In full bridge mode the NF4V should have no firewall, and the Client can see the NF4V.

 

 

 

Any thoughts /ideas?

router (default firewall setting) normally block icmp, etc. from the WAN port.

 

some allow the option to let them through, e.g. DMZ, port forwarding...
