The situation:

              OSPF ROUTERS   ZEBRA OSPF ROUTER (A)
                             ----------------------------
 internet --- 10.224.1.5 ---| 10.224.1.14 -- 212.125.x.x |--- 212.125.x.x
                            | external          internal |    network (B)
 internet --- 10.224.1.6 ---| xl1               xl0      |
                             ----------------------------

The problem:

It is not possible to connect to the internet from host A. Machines in
the network behind the ospf router (B) are able to connect. The host A
canno connect because the IP 10.224.1.14 is not routable over the
internet.

I would like to rewrite 10.224.1.14 packets with an routable IP adres.
But when i use the ipnat rule map xl 10.224.1.14/32 -> 212.125.141.129/32
to do this the router loses connection with the upstream ospf router.

How to rewrite IP packtes for the internet EXCEPT for the 10.x.x.x range?
The communication with the upstream ospf router should be untouched,
multicasting should be possible.

In advance, thanks!!
