re: Do you have your own DNS servers and domain? Or is your ISP currently
providing it for you?
Secondly, if you're connecting to two seperate ISPs, then you're probably
ending up with two different IPs for your DSL service endpoints (your ends).
I don't know a lot about DSL, not having used it yet....

I am aware of the dns issues like caching and I think it is a small
price to pay and am willing to deal with that.
But i just confirmed something I long suspected. my network's behavior
seems to change frequently. sometimes certain things work, then I test
them
later and they are not working. I just proved that my network has problems
dependent on where I am accessing it from.
if I telnet from work to my gateway at home, and ping an internal machine,
it sends on ping and nothing else happens. however if i telnet to a
different machine at home, then to the gateway, then ping the same internal
machine from the same gateway, it pings fine. so this explains why I
thought it kept working and not working; when I test from home it works, and
at work it doesn't work.
this makes absolutely no sense to me. just to clarify, I am logging into
my gateway and pinging the same machine, but get different results if I
telnet to the gateway from different locations.
I have been trying to get a multihomed system working for over a year
(because the phone company keeps ^%&#@! the dsl lines). I actually have
3 lines, one of which has racked up 7 months of down time in the past year!
that is why i need to multihome.
there are many tools; ipmasq, iproute2, nat, etc. i have no idea what to use
and I have tried them all in all combinations. each one works in some
cases but not others.
I have it to the point where internal machines can finally communicate
with each other, but now the external machines cannot reach the internal
machines.
what I want to do is simple; 2 dsl lines, each web server accessible on either
line. doesn't sound like a big deal. but I don't expect it to ever work
anymore. linux just can't do it. on usenet i find hundreds of people
trying to do the same thing without success.
