Running out of IP addresses so want to put site B on another subnet. Suggest best approach.
I have two sites linked with RF link 2 kilometers apart. Site A has a Windows DC+DHCP+DNS+Exchange server+file server; Site B has Windows clients & other IP devices. Now we are running out of available IP addresses. Now want to put site B on another subnet. Lets say 192.168.6.0 255.255.255.0. Now which is the best way to accomplish this.
Should I put one router at site B & put 192.168.6.x on its lan side. Should I use DHCP relay at site B so that it can get IP address from DHCP at site A. How to define scope at DHCP server at site A so that it allot IP address to both the sites accordingly.
Current scenario:
SiteA- Router(RV0120)-Win2012 DHCP-192.168.5.x 255.255.255.0
|
|
|(10Mbps RF link)
|
SiteB-Windows 7 *20 machines + IP cameras 192.168.5.x 255.255.255.0

Most routers are able to run a DHCP server, and that is what I would do for site B. In general it is best to keep traffic local as much as possible.

Hi Akash,
Which option do you prefer?
I think you should go for option (ii) since it would be best recommended to have a DHCP server at local site itself. Even in option (ii), are you going to use a separate windows DHCP server or the router as a DHCP.
Kindly confirm if the physical connectivity is as given below:
LAN A--Switch A---Router A---WAN Device A[Existing]<---->WAN Device B---Router B---Switch B----LAN B[proposed]

Existing :
WAN Internet Lease line---routerA---SwitchA--
What I get from your suggestion 2:
WAN Internet Lease line---routerA---SwitchA(1
Currently I would put the router as a DHCP as you proposed, if I get a budget later; I would try to put additional windows Domain controller with DHCP & branch cache mode.

Hi There,
Kindly confirm if the below:
i)
If you need assistance with the router configuration at Site B.
ii)
DNS servers being used at site A. If it is local to site A, the same IP could be configured on the router as well (assuming that the site B does not have a locally hosted DNS).

Thanks Ian Arakel,
I would setup DHCP at the router myself. Would set DNS at DHCP pool as 192.168.5.2 (site A DNS).
I guess this would accomplish the task.
The issue would come when Site B would have two gateways, one for accessing public internet & another to access domain controller/ exchange server & file server. I guess I need to create a routing table. To create the routing table I need your kind assistance. (I may ask this query in a separate thread if you say.)

Hi Akash,
Glad to know the above.
I would be rather happy to assist you to the best of my abilities.

Your default gateway on Site B is your router. The router then has info how to go to Site A, by creating a route for Site A network with the Site A router as gateway.
The RF connection probably requires that you use a transfer network, i.e. you set up the RF facing interfaces on routers with an own IP network (e.g. 192.168.254.1 and .2). Your existing and new routers are the devices having one 192.168.254.x and one 192.168.x.x address. and the route to each other site with the opposite's transfer network IP as gateway.

Everybody is right in his own way. In fact the task can be accomplished in either way suggested by you all. All depends on one's preference and available resources and benefits one choose.
Here also ideally i like to put another DC with ad integrated dns, dhcp and branch-cache role enabled. But i need a budget approval for it.
In case i did not get budget approval... I would prefer to put another router/gateway and keep local traffic local. And if i feel lazy or just want to get rid of addresses limit I would go for subnetting as suggested in this thread.
I would like to thank you all for giving so good alternative ways to resolve the issue and improving the network design.

Thanks guys. Everybody gave the valuable advice. It was very difficult for me to choose the best solution.
Each solution is the best; it is a matter of a choice between best practice or the current issue resolution.
