Hi,
I am new to this networking and trying to setup a small
network here using two RedHat Linux systems with IP-Masquerading.
I have read all the stuff I could find, expecially the IP-Masquerade
Mini-HOWTO, which I tryed to follow step by step, but I still can't
seem to get it working. My setup is as follows:
BOX1 Name = raven BOX2 Name = picard
204.215.83.136 192.168.1.1 192.168.1.2
INTERNET<----------> BOX1 <---------------------------------> BOX2
Diald PPP Connection Ethernet 10Base-T Crossover Cable
Modem
I seem to be able to ping between BOX1 and BOX2, but somehow I missing
something in BOX1 to tell it, that it has (2) two interfaces, because
I can't send anything out. I have tried many different setups but
this is how it is now. I have been struggling with this for
several days now and am frustrated, could someone please help
me and explain what I have done wrong here and why ?
The one ERROR message I do see is:
'ARP: arp called for own IP address'
I hope I have explained everything here, I really would like to
get this system up soon.
Any help or suggestions much appreciated.
Thanks,
