RV042 multiple subnets

[matt.siegel.cisco]

I have an RV042 running the most recent firmware, and I'd like to

know if the following is possible:

I'd like to have two subnets, 192.168.1.0/24 and 192.168.2.0/24

I'd like to have DHCP available on both, with some static DHCP assignments on both.

I'd like to have each subnet assigned to a port on the back of the router.

Example:

You plug a laptop into Port 1, and you get an address like 192.168.1.xxx

You plug a laptop into Port 2, and you get an address like 192.168.2.xxx

How would I make this happen?

Hi Matt,

The RV0XX routers support only port based VLAN. The multiple subnet feature allows the router to understand different subnet and communicate with them. The DHCP server may be configured for only 1 subnet. This goal would require an external DHCP service.

If you're looking for this functionality as described, you may want to look in to the RV180 router.

Thanks Thomas.

Just to clarify, with an RV180, I'd be able to assign physical ports on the back of the router to differnet subnets? 

I do all my VLANs in my switches, and don't want to burden the routers (or router appliances) with that.

Correct

I'm not familiar with Cisco's many product lines. 

If this is the kind of stuff I need to do, and upgrading is in my future, would you suggest moving up to the SA520, or even something like the Cisco 800 ISR?

Thanks again.

Depending on the required feature set. The SA520 is extremely feature filled but the pricing point is dramatically higher than the RV series products. The RV180 supports 5 vlans total, with the default vlan and the ability to create 4 others. If your interest lies with assigning ports to a vlan and having the dhcp service on the router, its simply a matter of how many vlans for how many users.

With that being said, you should check out the data sheets. The SA520/SA540 are obviously quite a bit more router.

I'm sorry to dig up an old post like this but I'm in the same situation as Matt... Just to clarify even more - The RV180 can act as a DHCP-server on several different VLANs (subnets)?

kind regards

I have 2 RV042s, a subnet on each. Currently R1 is connected to the WAN. I need to connect R2 to the WAN somehow. I only have 1 port on the ISP router that I can use. I need to have DHCP on R2 as well. Currently R1s subnet is receiving DHCP from a windows server. There was a patch cable plugged in between the two routers previously, however DHCP was assigning addresses two both subnets in various ranges. I'm not sure if any other traffic was crossing, I assume it was. I inherited this network and would like to set it up the correct way.
