I wonder if they helped unblock some of the ports or IP addresses Tivo says should be opened. http://support.tivo.com/app/answers/detail/a_id/402 The following ports (whether inbound or outbound) must be open to allow your TiVo box to communicate with the TiVo Servers, other TiVo boxes, and your Macintosh or Windows PC: * TCP port 37 * TCP port 80 * TCP port 443 * TCP port 2190 * TCP port 4430 * TCP port 5222 * TCP port 5223 * TCP port 5254 * TCP port 5354 * TCP port 7287-7297 * TCP port 8000 * TCP ports 8080-8089 * TCP port 8101 * TCP port 8102 * TCP port 8181 * TCP port 8200 * UDP port 37 * UDP port 123 * UDP port 2190 * UDP port 5353 If your TiVo box is having issues connecting to your home network, use one of the following procedures to check if required ports or IP addresses are blocked. 1. Make sure that ports 80 and 8080 are not being blocked by your router, firewall, or Internet Service Provider (ISP). 2. Verify that the following IP addresses are not being blocked by your router, firewall or Internet Service Provider (ISP): * 184.108.40.206 through 220.127.116.11 * 18.104.22.168 through 22.214.171.124 * 126.96.36.199 through 188.8.131.52 3. If the ports and IP addresses are configured properly on the router and firewall, but the box is unable to communicate with the TiVo service or another TiVo box, some ports or addresses may be blocked by your Internet Service Provider. Contact your Internet Service Provider for assistance.
