Re: TCP setup question

[Jim Langston <jimlangston@xxxxxxxxxxxxxxxx>]

As Christopher said your 192.168.106.21 is not a public (internet) address.

192.168.x.x is used for internal networks as are a few other ranges.
You need to talk to your ISP and get some additional information from them.

1. What is your public IP range?  Sometimes you only get 1 IP address, some-
   times you get quite a few.  13 addresses is common for a small office.
2. What is your gateway address to the internet?  This would be your router
   address.  It sounds like 196.168.106.21 would be your router address,
   but again, that is not visible on the internet.
3. Are you supposed to be using NAT (Network Address Translation)?  If so,
   you will need to learn how to set that up, I have no idea myself.  If you
   are using NAT I don't think you need public IP addresses, but again, I'm
   not sure.

Basically, the scenario you are stating here will just not work as it is.
You are missing some piece(s) of the puzzle.

Subject: TCP setup question

I have an interesting situation.  I have two Frame-Relay lines coming in.
One of the frame lines goes directly to a remote office in a different state
and the other frame line goes to the internet.  The IP scheme is as follows:

all internal traffic:  192.168.xxx.xxx
The internal network IP frame relay address:  192.168.100.21
The internet IP frame relay address:  192.168.106.21

I have created two interfaces:
192.168.100.254  255.255.255.0    ETHLINE1     *ELAN    (the company LAN)
192.168.106.254  255.255.255.0    ETHLINE1     *ELAN    (the internet)

 I have added the following routes:
*DFTROUTE        *NONE            192.168.106.21   *NONE    (the internet)
192.168.0.0      255.255.0.0      192.168.100.21   *NONE      (the company
LAN)

What I expected to occur was to have all internet traffic routed to the
internet port on the router and all other traffic routed to the company
frame relay.  This does not occur.  I can ping both router ports and I can
ping other LAN ports.  I can not ping any internet addresses.  We checked
the router and we can ping from the router to the internet.  I have added
the DNS servers (they are on the internet) and I can not reach them.  Both
interfaces are active and there are no port restrictions defined on the 400.

Does anyone have any ideas?

Thanks

Mike
