YES. YES. YES.

Many folks have had this question of late (or concerns about dynamic
addresses), so I'm morereplying to all those questions than to just yours.

If you have a working ppp setup, YOU have a setup which works w/ dynamic
addresses. Just don't have an IP address set in your options file and
the other end will tell you your address. Unless you do something silly
like tell ppp to not negotiate the address.

ppp works fine w/ dynamic addresses. Oh, and do set the "defaultroute"
option for your dialup connection, and pppd will make it all work
right. When you dial up, you will get a default route. When you quit
the ppp link, the default route will go away. When you dial up again,
you will get a (different but correct) default route again.

To recap, your ppp chat file should end with the connection ready for
pppd to take over. If you are using account name & password logins,
the chat script should send them (possably with magic to keep others from
seeing the pw in a text file). If you are using PAP or CHAP, the chat
script should end just when PAP or CHAP authentication will happen.

There are two how-to kits on ftp.macbsd.com for setting up ppp. They
both work with dynamic addresses.

Take care,
