IP Masqing

[Andy Ruble]

Hello,     I am a newbie at Linux and am trying to use a box to distribute a Cable modem to a LAN.  I have installed two NICs in my box.  Got these both to work.  I have been able to configure routing so that my box can ping both outside and inside.  The LAN can ping both NIC cards.  I assume since the 10. network can get to my WAN that IP Forwarding is working.  The LAN however can not get outside.  Does this mean that my provider is seeing a 10 network and not my assigned IP?  also I am having problems with DNS.  It will not recognize my DNS servers.  They are in the file but it will not ping them.  Sorry I am sure that this is all posted some place before isnce this is seeming to me as a common use for a linux box but I am sick and tired of trying to figure this out.  I just want it to work.  Thankyou for your time and consideration.   Andy
