Dreamgrid 5.491 is out. I installed it and experienced issues. For some reason dreamgrid is choosing random port numbers outside the range i forwarded for dreamgrid use. This means that random sims in my dreamgrid are unreachable when i go to teleport. In my case half the sims were offline. It seems if you do not use Upnp, that the latest dreamgrid skips ports in the allocated port list, and chooses some ports in a slightly higher range. If you have a small number of ports allocated, then this means that some sims will come online with a port number outside your forwarded port range making them inaccessible. So beware of this issue.
