seems like a lot of collisions for a home network. See below.

I don't understand how this works, and don't trust anything I don't understand.

This route should take care of all the hosts on your internal net and should be
added by ifup when eth0 comes up. I think the problem is in your adding the
routes with your machine as the gateway. Below I suggest to comment these out
of static-routes and bounce eth0.

Mine stops here since ip is dynamic on firewall at home

Is this the same as your ppp connection? How do you know what it is going to
be? I don't believe you need this but frankly don't know if it hurts or not.

I set forwarding on in rc.local but this seems to be working

Are you really running/needing netware. I think this is what the ipx stuff is
for. If not try deleting the above line and down

OK, this routing is my main suspect here. You should not need any of this for
your setup. I am wondering if the packets are getting routed back to you in a
loop since you told your box to forward all packets back to yourself with the
gateway. Comment this stuff out and do ifdown eth0; ifup eth0 and then take a
look at your routing table

Again I have no gateway entry here. Is ppp connection Dynamic ip?

I don't have these either. Already set in /etc/sysconfig/network, no?

Hmm nothing to get worked up about here from a networking standpoint but
security guys will go nuts. Do you need portmap for some reason? My guess is
no. same with inet unless you are using ftp or (shudder) telnet. Say it ain't
so!
what services are you running through inetd? Take a hard look at
/etc/inetd.conf and make sure everything is commented out that you don't want.
If nothing there, then use ntsysv or whatever and remove this service.
I also have never understood why linuxconf nees to be running so I don't run
it.

That is what I would do even though I did not see anything in the rpm that

Let's wait to see if we can get it working first :)
I would redo/ simplify the routing first and see what that does. It is this
that I am most suspicious of. Very strange and as I said earlier I think it is
routing everything back to you. so no packets get out. I may be
misunderstanding this and if there is a reason for this then I hope someone can
enlighten us.
Let us know how it goes.
