Hi!
Like many folks, I have a home network (say mydomain.com) on
ethernet (eth0) and dial-up access (ppp0) to Internet.
I've been reading about firewalling & securing networks.
And one thing mentioned is to ensure that internal addresses
do not come from outside locations. In my case, that requests
to/from mydomain.com should never come in from ppp0 or got out
over ppp0. I've seen solutions/code for the case of two
ethernets (eth0 & eth1) but not the mix of eth0 & ppp0.
Seems reasonable that code already exists. At the bookstore, I
perused through about six books (including 2 different Linux
Network Admin Guides), this wasn't really discussed. (FYI: I'm
running slackware linux 1.2.13 though I could probably upgrade, if
gives any benefits.)
Any suggestions & leads?
Sarah.
