RVS4000 And DHCP Server

Unanswered Question

I am a bit lost since I have not done this before. I inherited a job that is a mess and i cannot figure it all out. The setup I need to use right now is 2 RVS4000 routers that I need to hop together which I have not done before but I assume I would just hook up one port from router 1, to the WAN connection of router 2, router 1 is connected to the internet and to the server with DHCP enabled (SBS 2003). Normally I would use a switch, but the last guy went with 3 routers.


I guess my questions are:


1. Can I connect the 2 routers together like that (router 1 port 4 to router 2 WAN port)?

2. Can I still use the DHCP server or should I let the routers assign IP addresses?

3. This is the most important one, will I be able to setup Remote Desktop access from outside the network?


Thanks for any help you can give me.

Mr. Fudd,

Yes, they can be connected as you suggested. Only one can be a Gateway to the Internet on a connection to say... a cable modem. The second would use it's WAN port in DHCP or Static mode for its IP Address. However, under Advanced Routing it would be setup as a Router, not as a Gateway.

You could use the first RVS-4000... Your Gateway and give one subnet to all devices or use the vlan port setting to run vlan's on each of its ports and the second RVS-4000 could be on a vlan or not. And it too could give out vlan ports...

It might help you to tell us what you are trying to accomplish with this kind of setup?

here is what I have:


8 User Computers

1 Server (running SBS 2003 with DHCP running)

3 RVS4000 Routers

1 Cable Modem


And I think I want to make the following connections:


Modem to WAN port of router 1

Router 1:

(Settings DHCP Relay ON, running as Gateway)

WAN port to modem

Port 1 to Server

Port 2 to PC

Port 3 to PC

Port 4 to Router 2


Router 2:

(Settings DHCP Relay ON, running as Router)

WAN port to port 4 on Router 1

Port 1 to PC

Port 2 to PC

Port 3 to PC

Port 4 to Router 3


Router 3:

Same setup as router 2


Here is what really gets me and might explain some of the network problems I have been having. Under the LAN setting of router 1 the local IP address under IPv4 is 192.168.1.1 and i am ok with that, but then the next section for DHCP server settings they have the server address of 192.168.16.2 (which is the IP address of the server) and a starting address of 192.168.1.100. The server is handing out IP addresses of 192.168.16.X.


Noramlly when I use a switch, I would tell the switch, yes use my DHCP server to assign IP address, I assign the switch a static IP address based on the server scope and all is good. Also the server and the switch is on the same subnet even when I casade the switches, so the router and server will have an IP of 192.168.1.X, not 192.168.1.X for the router and the rest of the network on 192.168.16.X.


Thanks for the help and I hope that explains it a bit better.

I am sorry, I wasn't very clear... I meant what kind of isolation/security do you require; by Business / Companies or Departments / Workgroups?


Where your customers; should not and by your design cannot see each other’s PC's/Servers/Data, etc...


That's the kind of data needed to figure out what your VLan's and Subnet's and DHCP with and without forwarding should be.
