Routing problems with rawhide

I use my Laptop to route my brothers computer to the internet through
my UMTS modem.

With Fedora 8 it was enough to enable ip-forewarding and masquerading:
> echo 1 > /proc/sys/net/ipv4/ip_forward
> /sbin/iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

However with Fedora11 my brother can ping my two IPs (eth0 and ppp0),
but no ip of the internet.

Do you have any idea what could be the cause?
Btw. I have selinux disabled.

Thank you in advance, Clemens

My routing table:
[root at localhost ce]# /sbin/route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface     *      UH    0      0        0 ppp0     *        U     0      0        0 eth0
default         *              U     0      0        0 ppp0
