RV340 DHCP option 121 - static route

Hi,

I'm using an RV340 router. Can I push a state route to computers on the LAN? It seems like DHCP option 121 would do that but I don't see that available on my router.

Here is an example:

 

The RV340 DHCP is set up to give out addresses for 192.168.100.0/24 (network A). I have another network (network B), using 192.168.200.0/24. I set up a gateway on network A with the address 192.168.100.200. The clients on network A need to know it is the gateway for network B, which could be done with a static route.

For that one you need to setup 2 VLAN

 

VLAN1 default with 192.168.100.x/24

VLAN2 default with 192.168.200.x/24

 

Enable IP routing they communicate each other by default.

 

is this make sense ?

It might make sense. I have to consider my approach because maybe I am overlooking something simple.

 

Here is the topology:

[ LAN 200 ] --- [ Gateway GW2 ] --- [ LAN 100 ] --- [ RV340 ]

 

The second LAN is behind GW2, which has a firewall. So, I want the devices on LAN 100 to route directly through GW2 when they need to access anything on LAN 200.

 

I can make GW2 use NAT but I would rather have it route directly to the RV340. Then the RV340 can do NAT for LAN 200, like it does for LAN 100.

For VLAN 200 Subnet you need to make a static Route pointing towards GW2 (on RV340)

GW2 pointing default route anyway point towards RV340 here.

 

GW2 should have configured IP helper-address to get DHCP from RV340 for the LAN 200 IP address, Set it own gateway 192.168.200.x/24 (this is GW2 IP address (what you configured on GW2) in the DHCP Config.

 

Example :

 

192.168.200.x/24 Gateway 192.168.200.254[ LAN 200 ] --- 192.168.200.254[ Gateway GW2 ]192.168.100.X --- [ LAN 100 ] --- 192.168.100.Y[ RV340 ]
