Dynamic addresses on both ends of a vpn

[Reil]

Hi all,

our vpn is growing! tinc does a great job since one year now with a 
dial in connection via isdn.

Now i want to connect to the vpn via internet. My box is a notebook, 
having a dynamic ip.

The other end (firewall at work)  has a dynamic ip, too, but is 
registrated and reachable via a dyndns entry.

My question: Do i have to make one more entry for my notebook, or is 
the one for my firewall at work enough?
