Hello List -

Is there an "IPTABLES" expert on the list?  I telnet to my TNOS box from 
a Windoze
box on my LAN.  After I replaced my "ipchains" firewall with a new 
"iptables" firewall
I can no longer telnet to my TNOS box using my terminal program "putty". 
 What is
interesting is that if I shell out to DOS on the Windoze box I can 
"ping" the TNOS
box and "telnet" to it using the DOS "telnet 44.16.2.100" command.  I 
have attached
two files "dos.output" and "putty.output".  Both of these files capture 
what is going on
when I try to telnet to my TNOS box via "dos" or "putty".  The files 
were captured
using the "tcpdump" command ie "tcpdump -tqn -i eth1 > <output filename>.

I can also make my firewall file available to you by request 
"rc.firewall".  Any help
you could offer would be appreciated.  For whatever reason I just can't 
telnet to
the TNOS box using "putty".  Maybe I can't see the forest for the trees?

FYI, I can use "putty" telnet to connect to any other 44 IP number.  I 
can also use
"putty" ssh to connect to any of my servers on the LAN.

Any suggestions?

Regards,

Bill Walton KJ6EO (kj6eo.ampr.org)(44.16.2.100)
