Okay, I have a bunch of virtual domains that point to
private.opennms.com. They are NAT'd from the outside world to
172.20.1.10 (on the LAN).
However, when I am actually on the LAN (with a 172.20.1.x address) I
can't reach any of those external addresses, as going to
private.opennms.com terminates on the router and it is not NAT'd to
the proper box.
I get around this now with an entry in /etc/hosts for those domains to
point to 172.20.1.10 that I just comment out when I'm off the LAN, but
I'd like a better solution. I know that we can futz with the DNS
server and make this work, but we'd rather not have to if there is a
better way.
Remember that low-end routers seem to NAT regardless of where the
traffic originates. I've been told that this is actually incorrect
behavior but it made things easier.
