[nos-bbs] What are we missing?

[George (Skip) VerDuin]

We have been knocking our heads against a brick wall...
Dave WA8RSA and I K8RRA.
We ask for help.

I'm working with a local friend to install jnos2.0e on FC-4 to replace
his jnos2.0a on DOS.
Linux command line  "$ ping 192.168.1.31" and "$ ping 192.168.2.1" get
response from both ends of jnos tun0.
Linux jnos supervisor "> ping 192.168.1.30" gets response from the Linux
platform jnos is loaded upon.
  Thus I conclude "tun" is installed and working OK?
But here is a nasty problem:
  jnos BBS "> ping 192.168.1.1" does not get response from the LAN
gateway.
  Linux command line "$ ping 192.168.1.1" does get response from the LAN
gateway.

Here is the set of "clues" from our test protocol...
There are four nodes on this LAN -  DHCP supplies two, two are static IP
(DOS & jnos ...1.44, Linux & jnos ...1.30).
I find no IP duplication anywhere.
The Linux firewall is disabled & SELINUX is not installed
(so /etc/sysconfig/selinux is missing).
The "# cat /proc/sys/net/ipv4/ip_forward" responds "1".
  YET the results seem to indicate that the ip_forward is not working?
Linux command line "$ ping 192.168.1.100" does get response from one
DHCP configured node.
Linux jnos BBS "> ping 192.168.1.100" does not get response from one
DHCP configured node.

jnos on the DOS box continues to work simultaneously in most aspects
that jnos on Linux fails in.
DOS jnos2.0a supervisor command "> ping 192.168.1.1" does get response
from the LAN gateway.
Linux jnos2.0e supervisor command "> ping 192.168.1.1" does not get
response from the LAN gateway.
DOS jnos2.0a supervisor command "> ping 192.168.2.1" does not get
response from jnos (I expect this because there is no knowledge of route
to ...2.1 being thru ...1.31).

"Access" to Dos Jnos from remote internet is tested for ping and telnet.
The DOS jnos responds to remote Internet access at "wa8rsa.no-ip.org"
from my home QTH
The DOS jnos does PROBABLY respond to remote Internet access to
"hamgate.ottawa.drg-mi.org" EXCEPT the remote user does not receive it
(per the status line: jnos gets a remote request to answer).

Because I have been running a jnos on FC-4 and -5 for a year(+) there
has to be something I don't remember doing to make my similar K8RRA
installation successful.  Does anyone spot our omission?
