I know that this question has been asked before, but it's really important
to me that it will be solved in the upcoming version of m0n0wall.
For people like me who get a public dynamic IP from the ISP, use of
hostnames in the IPSec configuration would be the best solution.
Otherwise we will have to change the IPSec configuration manually every
time we get a new IP. It's also very important that when a change of IP is
made by the ISP when m0n0wall is running it must update the dynamic DNS
and after that the IPSec tunnels.
