question about dhcp and IP masqing

[Sean W. Bravener]

Hello all,

I just had cable set up at home and I want to set up a firewall for security
reasons.  however there is a proble with the whole setup and that is:  The
address is configured via DHCP.  IS there a way to set up a firewall without
knowing what the perm address is?  Also the ip address lease expires every
wednesday (roughly)

Thanks for any help
Sean
