Hi,

I'm a lowly programmer looking to flower into a beautiful systems/network administrator (focusing on linux). I've been filling in the gaps in my systems knowledge, but would really like to start filling in the gaps in my networking knowledge. At home I have standard DSL with a boilerplate Westell 327W modem/router/WAP/switch. I have a main workstation (I work from home) running Fedora, a laptop running Windows/Ubuntu dual boot, an HTPC running Windows Vista (that doubles as my NAS), and I just purchased a Dell Poweredge T105 on which I will set up an ESXi farm. I also have a gigabit 5-port unmanaged switch that I use with my Ethernet-connected machines. I have a pretty good grasp of simple router-y things, like port forwarding and setting up wireless security, but I have some huge gaps in my knowledge. Some things I really want to do are: - Set up my own DNS Server - Set up my own DHCP Server - Set up a linux firewall (like pfsense or monowall) - Set up my own email server - Configure more advanced router things like QoS - Set up a caching service, web filtering possibly as well - Work with Linux and LDAP and/or NIS - Work with Windows Server and Active Directory (FYI: I have a static public IP address) So I'd like some help figuring out the simplest way to work this out. The thing is, I can't just turn off all non-modem features on the Westell because I still need to be able to use the WAP with my laptop. But I'm not really sure what I can do yet.

Any help will be apprecited.

I didn't find the right solution from the Internet.
