Pretty much same as this thread, cept it's locked so I can't post in it:
http://www.geekzone.co.nz/forums.asp?forumid=66&topicid=57953

Instructions in that thread not working, wondering if someone can help me out

modem: 192.168.1.1
router: 192.168.3.1 (Asus RT N16 with Tomato)

When I plug straight into the vigor I can access it with http://192.168.1.1. I'm assuming the ip address doesn't change after adding the router

I've tried these instructions and various others, but http://192.168.1.1 just gives me connection time out

Anyone able to help? Would love to be able to access modem
