Networks

Let me summarize your question, if I understand it correctly:

1. You have 2 private network and one Internet connection. "Central" location has DSL to Internet and 56K FR link to "Remote" location.

2. You have some servers in "Remote" location, you want telnet to.

3. You want users from "Central" location to be able to browse Internet through DSL link.

4. Suppose you may want servers/users in "Remote" location to browse Internet through DSL link in "Central" location.

5. Lets say we have following IP addresses in use:
"Central" - 10.0.0.0/24
"Remote" - 10.1.0.0/24


Let look at two possible scenarios:

1. You have one router in "Central" location with 2 links (56K FR & DSL). In this case you should configure following routing in "Central" router:

10.0.0.0 -> ethernet (LAN)
10.1.0.0 -> Frame Relay 56K
0.0.0.0 -> DSL (default route)

In "Remote" location:

10.1.0.0 -> Ethernet (LAN)
0.0.0.0 -> Frame Relay (since it's only way out)

2. In case you have 2 separate routers in "Central" location, one for DSL and one for Frame Relay. In this case you must configure same routing in "Central-DSL" router with exception of:

10.1.0.0 -> "Central-FR" router

In "Central-FR" router:

10.1.0.0 -> Frame Relay 56K
0.0.0.0 -> "Central-DSL" router

That's all. Then you should configure your PCs with "Central" (or "CentralDSL") router IP address as Default Gateway.

If you have more questions - send me an e-mail.

Good luck.

Buy a Cisco Router with 3 ethernet ports.
create a dhcp server and move everyone to dhcp. configure e1 to route internet traffic, connect to dsl router
configure e2 to route telnet traffic, connect to 56k router
connect e3 to the lan.
