I dunno if these questions have been asked before or if there's something 
I'm just doing wrong, but for some reason I have a problem

Sisela installs quite nicely, gets an IP and sets up routing without too 
much bother, and as far as I can see everything works, i.e. sisela can 
ping www.google.com , sisela can ping another box attached to it 
( and that box can ping sisela. Everything works fine.

At this point I try setting up IP Masquerading/IP Forwading with the 

echo "1" > /proc/sys/net/ipv4/ip_forward

iptables -A FORWARD -o eth0 -i eth1 -m state --state ESTABLISHED,RELATED 
iptables -A FORWARD -s -o eth0 -j ACCEPT
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

However upon trying to ping www.google.com on, nothing 
happens. This is quite odd, since I've used the same code (with stuff 
like logging and some basic port-filtering) on both 
slackware and debian installations and its worked more or less perfectly.

have I assumed something sisela needs to be told explicity, or is there 
another way of doing this or something ?

Sorry if this is incredibly trivial and a waste of time, but I'm somewhat 

Oh and can the 0.3a code be compiled from the 0.3 ? I'd like sisela to 
boot with "pcifix" automatically and have a feeling I'll have to compile 
it into the code.

Thanks for your help, and thanks for what is otherwise a very cool disc :)
