ISO of a linux distro?

Would someone know of a version of linux that would meet my needs listed below

1. Boot from CD rom - pc will not have a hard drive.

2. I need to be able to "remote desktop" into a windows XP workstation and was wondering if and how this could be done

3. Built in firewall to protect in/out traffic

4. Not sure if this one is possible but with a CD version of linux, can you have antivirus software of some sort?

What I understand, you need specialized firewall to work on computer without hard disk and you want remote administration.

floppyfw

(floppy based linux firewall but no remote administration)

monowall

(flash card based unix firewall)

The other solution are IPCOP, smooth walls, etc (popular Linux firewall with remote administration but needs hard disk)

You can search/google for "linux firewall" (i.e. linux modified to run firewall %26 nothing else). Lot of them available free but check them with your requirement

most live linux distros will do what you are asking for. my personal recommendation is centOS. it's the most stable one that's free. if you have tricky hardware environment such as a wireless connection or raid, then try opensuse. if you have an old laptop, you can try damnsmalllinux. for comparisons, try distrowatch.com.

I do this with an Ubutnu ISO.

(not sure about the firewall part though)
