Hi! I need help in a very bad way here..
This is the situation:
DX4/100 - 32megs RAM - 6 gigs SCSI - Boca 6 port card - 2 NE2000 compat cards
I have one IP that is being broadcasted to the net. 198.161.220.180.
This IP comes from an ISP that we are connected to via ethernet on ed0.
Our internal network that runs TCP/IP and NetBeui is on the second
ethernet, ed1 and has been given an IP of 204.209.57.10, an IP that is
part of class C block but is not broadcasted/routed. I use parts of the
same 204.209.57 block for the rest of our internel network.I have built a
DNS server on 204.209.57.10 which works perfectly.
I run `gated' as apposed to `routed' because I was told it would be better.
Copy of my /etc/sysconfig: (sorry about including everything but I need
help bad and if someone could point out *anything* I should change I
would appreciate!)
#!/bin/sh
#
# This is sysconfig - a file full of useful variables that you can set
# to change the default startup behavior of your system.

What I am trying to do is use SLIRP to provide CSlip/PPP on the FreeBSD
box and also allow the internal network to get on the net from the
204.209.57 net. (noteing that it is routed by uplink).
I have TIS's firewall tool/servers installed but am finding it hard to
figure out how to install them properly to get full functionality out of
them.
My most frustrating problem is routing/gating/gateway.
How should the interfaces ed0, ed1 and lo0 be setup as far as
routing/gatewaying. Should I be IP forwarding? Is my kernel config
close to be right and how about my sysconfig?
Any example configs or any other help would be appreciated! Now I think
it's time to head of to bed after 72 hours of this;(
Thanks!
Phil..
