TomatoUSB

Hi guys, I need a help.
I have latest shibby tomato firmware without radvd. From my ISP I've got a IPes for native IPv6 setting.
settings are:

connecting segment: aaaa:bbb:xxxx::c/126
isp router: aaaa:bbb:xxxx::d
my router: aaaa:bbb:xxxx::e

subnet: aaaa:bbb:xxxx:0004::/64

DNS 1: 2a01:260:1:2::3
DNS 2: 2a01:260:1:3::3

settings window in gui is:
IPv6 Service Type - native IPv6 form ISP

Assigned / Routed Prefix
Prefix Length 64
Router IPv6 Address ____
Static DNS

Accept RA from WAN LAN

So please, could you tell me what exactly to put in the settings and I think this input in basic ipv6 config is not enough for working network.

thanks

There's no proper ipv6 support on tomato. works a bit here and there, broken in others, including dhcpv6. You're better off with openwrt if you need compliant ipv6 router.

I have to agree. I've only managed to get TomatoUSB to work with radvd. Getting it to work without radvd would be a trick and a half. If someone gets it working please post your configuration. Really ipv6 is still buggy on other systems as well. For example, I have two pathways to the internet. Each has it's own HE tunnel. If I enable radvd on both routers, then every linux based machine assigns itself two primary DNS address, one for each subnet. You would think that would give me double reliability, but actually what happens is it just completely breaks ipv6, so even the most basic of tcp-ip connections don't work. Since I can't get dnsmasq to serve addresses via DHCPv6 instead, I cannot even use the round-robin approach I use with ipv4 where each machine gets assigned the gateway for the first machine to respond.

Really the only thing that might still work is if I made sure each HE tunnel was on the same subnet. But when I tried that with HE, it complained a different IP address was already registered for that address…

the main and only selling point of tomato is qos. when you have more than 100Mbps, qos isn't really needed and you'll hit routing performance issue with the aging firmware kernel. so if you have the bandwidth already, it'll be time to move away from tomato.

To me the power of tomato USB is it presents everything I need to configure in the UI in a user friendly manner, but does not prevent me from configuring things with a command line. For me, QOS is more of an after thought. I have not even seen a screenshot of another firmware that exposes the NAS functionality that to me is so very essential.

Before I used Tomato USB, I used dd-wrt. In fact I still have some routers in use with dd-wrt. But it is the USB support that made Tomato USB the obvious choice. I've considered OpenWRT. At a low level, OpenWRT can do everything I want. With LuCi, X-Wrt, and Gargoyle, there are lots of options for OpenWRT front-end GUI. But of the three, only Gargoyle looks user friendly. I see no screen shots with NAS and VPN configurations for Gargoyle. So either they aren't there, or they aren't stable enough where they found it worth showing off. I certainly have the technical abilities to configure everything from the command line. However, that means my wife would be royally screwed if she ever needs to make changes when I'm out of town.

So while TomatoUSB is not perfect, it does work well enough for my requirements. It is only in the nice to have columns that it is a bit lacking.

What's the criteria for having "IPv6 working"? I just spent the whole day figuring it out by way of tunnelbroker (6in4static) and the HE.net certification course, such that on my RT-N66U w/ Shibby 109-AIO:

- test-ipv6.com showing 10/10
- successfully routing web/email servers strictly on ipv6
- reverse dns via dns.he.net
- not using qos, dhcpv6, just router advertisements and client autoconf

i was about to relax while exploring whats out there with ipv6, but this thread is casting some doubt on my level of "completeness" with this…

Ipv6 support in tomato was written by someone who only had access to hurricane electric tunnel. So that's the only working ipv6 support that it'll be good at. Plug the tomato into other transition links or native ipv6 connection and it'll fall flat and fail.

So long as you are using a single routing, and an HE tunnel, it should work fine. With that configuration, using radvd for address allocation and routing works fine. It is if you try to do something more advanced, you will feel have problems.

Initially when I started using ipv6 a couple of years ago tomatousb was perfect for my needs. Very little traffic actually used IPv6, and basically I just wanted a tunnel so I could play around with it. Now, I find about 40% of my traffic will actually go through the IPv6 tunnel. As such, I want it to be as mature as my IPv4 connection. So I do want it to play nicely with my dual router/internet connection configuration. I don't want my wife complaining because she can't watch youtube because I'm performing maintenance on one of the routers.

However, most of the problems I experience with IPv6 are not at all problems with tomatoUSB. For example, one huge pain in the neck with IPv6 is if I establish an openvpn connection on my desktop and then start utorrent, about 40% of the traffic will end-up going through the IPv6 tunnel instead. Consequently I do not use IPv6 on machines with vpn.

Instead of a NAT, IPv6 uses limited use addresses. The problem with that is, it makes it much harder to transparently redirect traffic. For example, with IPv4 I can configure my router to redirect different machines through different VPN connections with no changes to the machines themselves. The same can probably be done in IPv6, but it is anything but easy…

I just installed openwrt on one of my nslu2's that have been collecting dust. As far as ipv6 support, I'm not impressed. The web interface doesn't support ipv6 at all. The command line stuff is pretty much the same as what you can do in tomato USB from the command line. The only thing you gain is a newer kernel version. But ipv6 is already stable in the kernel tomatoUSB uses. Particularly when it comes to an NSLU2, the wiki suchs, as they don't tell you how to configure IPv6 to accept RADvD broadcasts, or DHCPv6.

Edit: I found if one simply installs the kernel module, then openwrt picks up the Radvd broadcast and configures automatically. The configuration setting even appears on the UI. Really, the biggest show stopper for me is using openwrt as instead of tomatoUSB is that they still don't have a "stable" build for Asus RT-N16 routers. Even though Tomato USB has supported this router for at least 3 years… The other big problem I found is to transition to openwrt I would need to be prepared to build a lot of custom packages. Even very common things like "e2label", "parted", and "rsync" are missing. Although, I see at least 5 times "parted" has been submitted in the last 1.5 years. It never actually makes it into the official builds. So it is very likely I would have to keep manually building the packages I create myself. I might eventually go that route, as optware is basically abandoned ware, and entware suffers the exact same problem of needing to build my own packages. But for now I think I'll just stick to tomatoUSB for my routers, and just use openwrt to play around with on my NSLU2's.

Openwrt is embedded Linux, and Linux ain't user friendly lala land. Working right and correctly is more important than pretty gui because proper users build their own firmware without gui.

There's nothing unstable about ipv6 in tomato. It just doesn't work right with other transition ipv6 links or native ipv6. It's just as simple as that.
