Something is odd about the DIR-130 router. There are times when I change a setting, save, and then cannot get back to the UI page. I can ping the router ip address, get a reply, but cannot get back in to administer. Most of the time I have to power down the router, then I can get back in.
I also see something similar in VPN'ing. When I cannot get into the UI, it seems I cannot connect to the DIR-130 VPN server either. I've read about UI problems with this router, this seems similar to what I've read, so I am wondering if these type of problems have not been totally fixed.
