[ale] Gateway Problem

[Brian J. Dowd]

If anyone is familiar with gateways I sure could use some help on
this...
My machine has a static IP of 206.98.xxx.xxx given by my ISP  to use
when I ppp connect using his gateway of 206.98.aaa.aaa
Locally eth0 is set to 192.100.bbb.bbb on my company's WAN (yes I know
it should be 192.168.bbb.bbb)
Using linuxconf I can set up my gateway to either allow all users on my
WAN to access my web server *or* to make Apache serve users on the WWW.
What I can't do is figure how to make my Apache serve users on my WAN
*and* still be able to use my ppp connection to my ISP so that I can
browse (not serve www).
Are two gateways possible?
I tried 'route add -net 192.100.xxx.xxx netmask 255.255.255.255 eth0' to
no avail....
Any help is most appreceiated!
