dsl setup - finally

[tyche <tyche ica net>]

after fighting with the local phone co for three years, we are finally getting 
a dsl connection.

would like some very badly needed advice.

1) i am getting one static ip and one dynamic ip. the static ip is for my 
personal box that serves as the local file server, ftp server, web server. i 
have NOT enabled telnet nor am i going to.

2) sendmail, procmail, fetchmail. any good FREE guides available for these.

3) since my machine is always on, i know that i will need a very tight 
firewall. with several ports open, obvious ones are 80, 21, 110, 25, and 
whatever yahoo uses. (i dont know this, but am thinking it is 80, but i am 
not sure.) i will need to connect with ftp, www, and ssh to this machine 
periodically. since i think my isp will be blocking those ports, how to 
change those ports, specifically, ssh to something else at the command line.

4) any other pitfalls with pppoe that i am not aware of. any  and all advise 
would be appreciated.

btw: i still have my alcatel nic asdl modem that my gf wanted to give back 
after the fight with phone co started.
