VPN with CIPE

Dear all I would like to configure a VPN with CIPE between a Redhat 9
Maschine and a Windows Client. I read capture 6 of the RH documentation
about CIPE install and config, but I still have a question: How do I
need to configure CIPE to handle the case when the internet provider for
the RH box and the one on the other side of the internet renew the ip
adresses without losing connection between these two clients?

Thanks in advance
Peter

To build the tunnel you need at least one fixed address.
The tunneling cannot connect if it does not know the
address of the other end. This applies to *all* tunnel
protocols.

One end may be dynamic, however. It has then to build
the tunnel with the fixed address of the other end.

If the NAT does not change during the connection, you
could maybe use some dynamic DNS to resolve the peer
address. Point your favourite search engine to 'dynamic
dns' and follow the links.
