Post the outputs as linuxwrangler said. Also, are you trying to masquerade other boxes? If so, did you compile tke kernel with the specific options? More info on what is needed in the kernel, in the IP-MASQ HOWTO available at <a href="http://www.linuxdoc.org" rel="ugc">www.linuxdoc.org</a>

thank you both of you. i did manage to solve the problem. the problem was with the host i was trying to ping.<br />
i realized that i could ping the host from behind the linux router but not from outside the linux router.<br />
the problem was that the gateway had not been defined properly on the host.

what necesary options have to be enabled in a linux box to make it act as a router ?<br />
i have done the following in the proc filesystem :<br />
<br />
ip_forward=1<br />
rp_filter=0<br />
ip_always_defrag=1 <br />
<br />
(above may differ a little as i am mailing this at 5 in the morning with no sleep :-) )<br />
<br />
the linux box is acting strange, it allows ping to certain hosts and does not allow to others and after sometime starts to ping the hosts it was not pinging earlier.<br />
<br />
please help<br />
<br />
thanks

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.
