My ISP provides native IPv6 and it works great when I connect directly with my macbook to the ethernet port. I get a ipv6 assigned and all IPv6-only sites works great.

But when connecting through my Netgear WNR3500L router (running Tomato Firmware v1.28.7496-Toastman) IPv6 enabled sites won't work.

How would I configure my router for this to work? I don't have any "assigned/routed prefix" which the "native ipv6" settings in Tomato require, nor did I receive any settings from my ISP (it just worked).

If your service provider is TekSavvy: You need to register for IPv6 Services by going to They will supply you with new login address and credentials Next, you need to configure Tomato Router Bssic->IPv6 Select DHCPv6 with Prefix Delegation Prefix length:64 Set up a DNS such as 2620:0:ccc::2 and 2620:0:ccd::2 and 2001:4860:4860::8888 Accept RA from WAN To correct a Tomato Bug where random forward routes are generated Administration->Scripts->[Wan Up] Paste the following: echo 0 > /proc/sys/net/ipv6/conf/nvram get wan_iface/accept_raip -6 route flush default dev nvram get wan_ifaceecho 2 > /proc/sys/net/ipv6/conf/nvram get wan_iface/accept_ra
