Need the software names and types needed to have a
subnet  call the main network (as needed). The the main network call the subnet and maintain the correct IP's  every time need  static  IP's and routes.
What would be used as a central hub ? (RRAS?)

Any Ideas would Help

RRas will do It.

Cisco will do it.

What you're looking for is On-Demand Dialing, which is available for most any good router.

Cisco, for example, allows you to define a list of "interesting" traffic. Every time it sees interesting traffic on the net, it will trigger a Dial session to connect with the remote site. Other traffic (uninteresting) gets to go if the connection is established, but does not trigger a new connection if it isn't. Uninteresting traffic also doesn't reset the inactivity timer, so if only uninteresting traffic is moving in your link, it will be disconnected as soon as the timer reaches 0.

I used Cisco as an example. Others have a similar solution, I'm sure.

This what you were looking for?

Kinda We have sites (nonetyeT). will need to have something on that subnet call local net and become part of it.

However I the something on the local net
need to get to some device on the remote(subnet) the reverse needs to occur.  In both cases the IP's need to be static. Have tried a dailable 3Com router into an RRAS server but when started from the remote cannot find out how or if we can do a reverse route...

Fulltime WAN half the time!

If this would work we could start it quickly and work on the full time after.

YES! Thats exactly what I was talking about! Here goes:

Router A is on your main network. Router B is on your remote network. You have a modem on a serial port of each router. Router A knows that the remote network is on the other side of his modem. Router B knows that the main network is on the other side of his modem also.

That way, when router A receives traffic meant for the remote network, it brings up the link. When router B has traffic that needs to get to router A, it brings up the network. Anyhow, for this to work (and it does), router A and router B KNOWS what network is on the other side of which serial port, or phone number, etc.

Make any sense?
