And here I am responding to my own post with a partial answer.
It appears that though the kernel naturally wants to send response
packets back from whence they came, there had better be a "route"
thataway before it can.
I did this:
[root@borg root]# route add default gw 192.168.1.1
[root@borg root]# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.100.0 * 255.255.255.0 U 0 0 0 eth0
192.168.1.0 * 255.255.255.0 U 0 0 0 eth1
127.0.0.0 * 255.0.0.0 U 0 0 0 lo
default 192.168.1.1 0.0.0.0 UG 0 0 0 eth1
default 192.168.100.1 0.0.0.0 UG 0 0 0 eth0
[root@borg root]#
It bothered me to have two default routes, but now it seems to work.
I can ssh in via my new DSL link, and I even did a manual e-mail via a
telnet to port 25.
So here are my next questions:
1. Is this right, or am I getting by on a technicality and things are
actually quite hosed and just don't know it yet? ("Having TWO
~defaults~? Yeah, right!")
2. What is the right way to get that route added automagically next
boot? It seems it should be part of the eth1 config, but where?
There seem to be quite a few ifcfg-eth1 files in /etc/sysconfig*, and
I think they do all have "GATEWAY=192.168.1.1"s in them. Certainly I
could put my "route add default gw 192.168.1.1" someplace like
rc.local, but that seems really wrong. What is the right way?
Thanks,
-kb, the Kent who is still learning, about to start looking at Mara
DNS to replace the ornery djbdns before he starts getting too fancy
with DNS.
* As in three. What are they all for?
/etc/sysconfig/network-scripts/ifcfg-eth1
/etc/sysconfig/networking/devices/ifcfg-eth1
/etc/sysconfig/networking/profiles/default/ifcfg-eth1
