Nick, You need to un-check the 'Filter Internet NAT Redirection.' When checked it will prevent the redirection you need. The hosts file setting seem helpful in getting the TCP mode login process started when NAT loop back is not working. This really isn't helpful because it when UDP kicks in the NAT loop back is still needed. Here is a link to a cisco discussion of the issue: http://homecommunity.cisco.com/t5/Wired-Routers/What-s-the-purpose-of-Filter-Internet-NAT-Redirection/td-p/63857 which contains this: If your local systems send packets to the -public- (external) IP and port of your internal servers, then if the filtering is turned on then the device will deny those packets; when the filtering is turned off, the device will re-address those packets and send them back inwards. In this situation, the source of the connection is local and the destination ends up being the local server, but the address used by the local computer was the outside address instead of the inside address. - Gary Beck ----- Original Message ----- From: Nicky Perian To: Gary Beck ; [email protected] Sent: Sunday, August 12, 2012 3:37 PM Subject: Re: [Opensim-users] Region handshake does not complete
e4200 settings that work for me. http://picpaste.com/NAT_Loop_Back_e4220-FGNLyJLJ.JPG http://picpaste.com/NAT_loop_back_port_range_triggering-LZJD67rg.JPG each hosts file 192.168.x.x my.dyndns.domain These might not be the best. I rely on each computer to be firewall protected and leave the routers open to prevent firewall fighting. Thank you for the responses. ---------------------------------------------------------------------------- From: Gary Beck <[email protected]> To: Nicky Perian <[email protected]>; [email protected] Sent: Sunday, August 12, 2012 11:55 AM Subject: Re: [Opensim-users] Region handshake does not complete The CISCO 'NAT loop back' item is 'Filter Internet NAT Redirection.' I'm not at my usual location so I can't check how it's set on my e3200. I think un-checking that option (the default) allows the redirection of your external IP back to your local LAN. It's one of the firewall settings. ----- Original Message ----- From: Nicky Perian To: Gary Beck ; [email protected] Sent: Sunday, August 12, 2012 11:40 AM Subject: Re: [Opensim-users] Region handshake does not complete Thank you for the reply. I have a cisco e4200. It has settings for port forward, triggering, DMZ, and a means to place a gaming app at a specific priority. But,it has no mention of NAT loop back. I assume that NAT loop back is just another name for one of the other port handling features mentioned above. I have searched google and not found how to set NAT loop back. Actually, about the only mention to pop up is OS wiki. How is NAT loop back set up for any cisco router?

I'm assuming that would be your dyndns domain name + a port number. However the server send the resolved address, not the domain name. So the viewer will be getting the external IP + port number. This can work if you local network router has NAT loopback enabled. If not the viewer attempts to use the address and doesn't reach the server. The host file settings would be effective if at handshake time the server sent domain names to be resolved but it doesn't. Hope this helps. - Gary Beck ----- Original Message ----- From: Nicky Perian To: [email protected] Sent: Saturday, August 11, 2012 9:57 PM Subject: [Opensim-users] Region handshake does not complete I am running a diva under win 7 64 bit. Same machine as several linux VMs. I want to connect each VM to the opensim sever. The VM's network cards are set to receive a DHCP ip from the router and that works. I can connect to any external grid (SL & OS) from the VM's. I have a dyndns domain name assigned to the cable company external IP. The hosts file in the VM is set to server's lan ip and the dyndns domain name. Ping to the domain wraps to the server IP. At viewer start I receive the splash from the server. The login will not get past establishing the region handshake. Hints please.
