Routing problems with Fedora 11 (worked on fedora8)

[Clemens Eisserer]

Hi,

I've already posted this to fedora-list twice some time ago, and once
in fedora-forums, but never got any answer.
Please apologise the cross-post.

I have I server which routes a private network to the internet through ppp.
All I had to do on Fedora-8 was:
> /sbin/ifconfig eth0 up 192.168.1.1
> echo 1 > /proc/sys/net/ipv4/ip_forward
> /sbin/iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

However with Fedora-11 this doesn't work anymore. Packes simply are
not forewarded anymore.
The routing tables look 1:1 the same:

Fedora8:
> 10.64.64.64     *               255.255.255.255 UH    0      0        0 ppp0
> 192.168.1.0     *               255.255.255.0   U     0      0        0 eth0
> default         *               0.0.0.0         U     0      0        0 ppp0

Fedora11:
> 10.64.64.64     *               255.255.255.255 UH    0      0        0 ppp0
> 192.168.1.0     *               255.255.255.0   U     0      0        0 eth0
> default         *               0.0.0.0         U     0      0        0 ppp0

Any idea what the problem could be, or how I can debug that problem.

Thank you in advance, Clemens
