Hi,

I am trying to setup my ethernet LAN with internet connection from
internet provider via PPP link. I am having some problem in routing
PPP incoming traffic (from internet) to my entry machine's ethernet.
To give some background here is how my setup looks like:


						     ^ to internet
						     |
      port-server                                    |     Nameserver &
      	 |--------------|                     --------------- internet
         | lp1.tiac.net |                    | zork.tiac.net | gateway
         |  199.0.65.12 |                    | 199.0.65.2    |
         -------|--------                     -------|-------
                |				     |
                |            Subnet 199.0.65 (commercial internet provider)
      ==========|=================================================
                |
                |ppp link
                |
     ---------------------- 
     | alpha-ppp.dtix.com  |
     |     199.0.65.53     | 
     |---------------------|
     |   alpha.dtix.com    | 
     |   198.62.174.1      | 
     ----------------------  
                |
                |ethernet
                |            Subnet 198.62.174 (our own class C network)
      =============================================================


Versions of OS running on alpha.dtix.com is SCO SystemV version 3.2.4 with
TCP/IP runtime 1.2.1 with NET382 SLS applied. Our PPP link is working fine.
We are supposed to use internet provider's primary and secondary nameserver.
Here is what I am not able to configure.

(1) Configure DNS at our side, which is on alpha.dtix.com and will make use
    of internet provider's primary and secondary nameserver. They told me that
    I need to configure my nameserver as unauthoritative secondary nameserver.
    I would like to get some example configuration file like, named.soa, 
    named.hosts, named.local and named.boot which will help me in configuring
    my nameserver to make use of their primary & secondary nameserver. Also,
    what changes I need to make to any other relevant files on this machine
    or any other machine on my LAN. I read O'reilly's book on DNS and BIND,
    also another book Managing TCP/IP networks from O'reilly. But they
    discuss generally primary/secondary DNS setup in one domain. I couldn't
    find any example where two domains (dtix.com and tiac.net) are involved.
    I am sure someone out there must have gone through my situation.
    Any help please ??

(2) This question is for SCO sysadm's : I read in comp.protocols.ppp
    that SCO TCP/IP runtime has some bug which will not allow such
    co-existance of local ethernet with PPP connection and route traffic
    on appropriate channels. They have some patch for this. Has any body
    applied this patch? or does it work?

I would appreciate any help in this regard.

Thanks,
