[Masq] Adding more Internal Interfaces ???

[Engr.Wilfredo Santos]

Hi, I'm using RedHat 7.3 (download version), and have configured it for IP Masquerading and it's Dial-in with no sweat, it's IP Masq ready.  Now, I have to choose between 2 rc.firewall-simple to run manually, they differ with INTIF, one is eth1 and other is ppp1 (for dial-in).  I wonder, How can I enable them simultaneosly, so that more people will enjoy the free ride. I've tried INTIF="eth1 ppp1" and it didn't work. and what does ip_conntrack (1023 buckets, 8184 max) means ?? I know, there must be a workaround on Iptables and that I do not know, how !   I will really appreaciate any help. Many Thanks, Wilfredo Santos
