I installed the new version and tried it without success. The machine
phoenix.rhein.de has an default route which points to petium.rhein.de,
and a PPP link to the outside world. I want to route http packets over
this link, instead of routing them over petium. So I configured
IPFilter/IPNat as follows:

 | pass out on ed1 to ppp0 proto tcp from any to any port = 80

and 

 | map ppp0 0.0.0.0/0 -> 193.175.163.115/32


I also tried:

 | map ppp0 193.175.27.172/32 -> 193.175.163.115/32

but I had no success. phoenix sends the IP packet out on the right
interface, but the From-Address is still the one, phoenix has on the
ethernet. And this address is, unfortunately, not accepted on this
line, for reasons that are beyond my control. :-(

Any idea what I am doing wrong?
