RE: [MLUG] ipchain slowdown?

["Spurling, Shannon " <EMAIL:PROTECTED>]

If they are in the same subnet, public or private, IP chains should not
affect that. I would try doing things by IP number, that lets you know what
layer the slowdown is occurring at. Now, I think that in order to pull names
out of the hosts.conf file ( is that the right file? it's been a little
while) you have to let your resolver pretty much time out in some cases.
Also, I've found that IP masquerading in general slows DNS requests down to
a crawl. You really have to run bind on your firewall, or some other
internal server in order to get things back up to speed. Also, if you are
running bind, make sure it's set up to serve stuff out on the internal IP
address. If not, requests have to route through and then back to the public
side of your box.

Subject: [MLUG] ipchain slowdown?


I implemented IPchains on my machine connected to the Internet and now
communication with other machines on my LAN is really slow. It takes maybe
30 seconds to ssh between machines when they are idle and so is the
network. Connecting to the Internet doesn't seem any slower.
