[Opensim-users] Awaiting region handshake

Pete,
Here's a list of routers: http://opensimulator.org/wiki/NAT_Loopback_Routers
There was also a write-up on using... address translation or routing tables on a Linux system to substitute the local IP address in place of the external on the local lan here: http://opensimulator.org/wiki/Network_Settings
It's difficult to find marketing material that mentions loop back. What I did is get the router user guides and search those for the loop back function. In the Cisco/Linksys manuals they talk about "Filter Internet NAT Redirection"
Filter Internet NAT Redirection-This filter prevents a local computer from using a URL or Internet IP address to access the local server. Select this option to enable the filter. This option is disabled by default.
I've used both a WRT54G and the E3200. They support loop-back. Filter Internet NAT Redirection disabled is how you turn loop back on.
Finally - there's a very ugly process where you can revise the hosts table entry as needed. Local address while logging on locally. External address while logging on remote. Once you're logged in things are mostly OK while you stay inside a single region. I've done that while testing.

Hmmmm, OK.. that sounds logical. How do I get around this? Without buying a new router as there would be no way of knowing if it supports loop back until its in and running.

Browsing from outside your lan using myusername.dyndns.org:9000 to get the hippo page is some key info. Now I'm still wondering what you're doing in the hosts file. If your dyndns is set up to point to your external IP you shouldn't need to modify it using hosts.
