router firewall distro choice...
I have been lucky enough to get a halfway decent pc given to me, making my old and very slow pc somewhat redundant. However, I seem to remember reading somewhere that there is a distro of linux that can turn such a pc into a firewall/router if I cram it with network cards, this could prove to be an ideal solution to my networking needs.
has anyone had experience of such a distro? I looked on distrowatch, but I couldn't swear as to which distro would suit my needs best. it'll have to be lightweight, but I won't be asking a lot from the processor or graphics, so I'm guessing it's been done already.
advice would be greatly appreciated.
thanks in advance
