Windows 7: Router on different subnet to network - worried?

Router on different subnet to network - worried?

Hi all,

Quick question,

I'm just wondering what are the complications of doing this?

We have our network on the Subnet Address from -

I have set up a router, and this gives out IP addresses from to whatever with subnet This is connected into our network and therefore we are able to receive Internet/Network shares etc.

Now I'm thinking is this a plausible thing to do? Because everything seems to work okay. We are slowly running out of IP addresses so this would help this cause. Obviosuly from the Server side I won't be able to see what our DHCP server will be giving out and will have to do so by going into the Router's Web Console - but I'm not too worried about that and computers not being able to see each other, not worried about that either.

P.S. Not known to me, we had this set up on another Router and there hasn't been any problems with this.

Just after a bit of guidance on how this effects the network/bandwidth etc?

There is a reason why people spend years and lots of money to become experts in networking... it can get complicated setting up a network for a business. I do not happen to be one of those network experts; but I hope to watch your thread and see what other forum members say.

I'll add a warning that you need to meet any applicable laws (or maybe just rules) that govern how your business network must be setup. For instance, on this side of the pond, there are rules that must be followed if you process/retain credit card info on a computer.

If the router that is handing out IP addresses in the to range is a commercial grade router, then it should allow you to expand the DHCP range to more than 254 IP addresses. Then all of your computers could be served by that one router. But doing that might be against the rules (as I understand them) for processing credit cards over here. The network must be segmented.

Before we discuss the downside of adding another router to your network, I would like to know what the manufacturer and model number of the router that is currently handing out IPs in the to range.
