As I said in  a previous email   I though I had solved the problem by 
dicarding some sanity check rules.

I had the system running fine for a day then sudddenly I  keep getting these 
flood  of  lines like the  below in /var/log/messages:-

(remark the internal net  does not use the 192.168.2.0/ subnet )

######################
Jul 16 13:37:50 biker kernel: [   57.617604] IPv4: martian source 
192.168.2.254 from 192.168.2.1, on dev eth1

I have checked  the 48-bit mac code wich I gave as as 11 22 33 etc  does not 
represent the MAC address of the NIC asigned as eth1 ( or any ther NIC  on 
tjhe mchine. )

I also  put  a line such as 
iptables -A INPUT   -s 192.168.2.1-192.168.2.254
-j DROP

(or some such )
but it made zilchdifference.

Is this done by the  by the isp or the phone company or what?
suggestions welcome

any ideas?

and 
what is a martian source ?


comments welcomed
sincerely
