i have leased line connected to cisco router through int serial0/0/0 ip address 194.x.x.x
, along with free public ip address
what iwant is to configure mail server and ftp server
and the confusion is , do i need to asign acl in the router to port forwarding my public ip address to the local mail and ftp server
or do i need to assign one of the fastehternet in the router with public ip and thier subnet mask and use these public ips for the servers,
or what shoud i do please i need some one to imagine the case .
any advice will be appreciated
