 |
|
Hello NG-
I recently got NAT running on our 2621 (I'm quite new to Cisco routers).
I have three global IP's serving up ports 80, 20/21, 22 a couple of servers.
These ports work fine from the Internet, but not from our network. ie, I
can't browse to the httpd servers via the global addresses. We need this
functionality to be able to verify that things are working correctly.
Does what I have said make sense? I'm sure this is something normal and
that there is just one more setting that I need to give the router in order
that it work right.
Thanks,
Jake

You will not be able to do so. The router will assume you are spoofing an
internal address. Basically, you are trying to go out and right back in
through the router, which it will not do.
You will need to dial out to a ISP to do your testing.

There _must_ be a way to do this, because the Linksys NAT routers we just
upgraded from did the job without even asking them to. (Or is that some
kind of special situation?) I'm not sure how, but when I find out how to do
this, I'll let you know.

Well, I've set up a DNS server on a Linux (Debian 3.0) box using dnsmasq.
It's a simple setup, dnsmasq works out of /etc/hosts and /etc/resolv.conf.
It's not the solution I'd like to have, but it's working great for the time
being.
