ADSL Routers supporting fail-over

Was reading this month's SACM and they did a review on the new WiPod from Strattice: http://www.strattice.com/index.php?option=com_content&task=view&id=3&Itemid=13

This would be really handy in my situation as we are very often capped and the automatic fail-over to another ADSL account would help a lot.

Do you guys know of any other router (perhaps less expensive) that supports this type of fail-over capability? Particularly PPPoE to PPPoE rather than PPPoE to 3G, etc. I know that Billion has a router that supports the latter.
 
Have a look in any of these [searchforum]Wipod[/searchforum] related threads
 
the billion biguard 30 can failover (and loadbalance) two wan ports. If you need more the dreytek vigor can do 4 wan ports and i've also seen a little edimax device than can do 4 ports and was by far cheaper than the above options...
 
my main requirement is that if one of my accounts is capped that it will fail-over to another account that i specify.

perhaps you can share some ideas on how i can do this with a load-balancing router? or software? i could put my routers in relay mode or something, does anyone know how it can be done?
 
Cisco 837/877 can both do it. Got ours set up with 5 accounts with auto-failover.
 
awesome, i'll check them out. what's the cost more or less on one of those?
 
I see the 837 has reached end-of-life. You reckon the 878 will do what I need?
 
877 is the correct one. It will be expensive (R3200). You can get a used 837 off ebay for about a grand, and it will work just as well (providing it has the right version of code on it).
 
R3200's not so bad. ok but you're certain it can fail-over if an account gets capped to another account on the same WAN port?

how does it determine that the connection has died? because these days the router does not lose its IP address when it's capped. Does it ping an external address and fail-over when it doesn't receive a response for x amount of mins?

Thanks for the help by the way :)
 
We've done it using a function called "object tracking". You configure the router to ping or do a TCP connect to a specific ip. After the specified number of timeouts, the object will go to a "down" state, and the conditional routing will choose the next best route (i.e. the 2nd, 3rd, 4th, etc PPPoE connection). If there happens to be a problem on the ADSL network, and the account wasn't really capped, the object will go into the "up" state and the routing will go through that account again.
 
very cool. pretty much exactly what i need. we go through about 10 accounts in a month and it's such a head ache changing them each time. even if i can't load all 10 onto the router at least there'll be less down-time while it's waiting to be changed.

thanks for the advice.
 
There's no upper limit specified, but Telkom may limit it on their side. Let me know if it works with 10.

BTW, which accounts are you using? We use SAOL 20GB accounts - they're quite decent.

how would they limit it? does the router physically establish connections on all 10 accounts and then just use the ones that work? or does it only connect the next one once one goes down?
 
All of them are established at once the way we've done it. So if there's a limit on the number of PPPoE connections, you may run into issues. I know the limit is more than 5.

You can also split local/international with the method above, since multiple connections are active at once.
 
sounds good. nah man, i gotta use 3gb telkom accounts, it's a long story. :)

tell me - your 877 how much DRAM and Flash does it have? I see standard is 128mb dram, 24mb flash? just wondering if i need more than that to do this type of connection redundancy.

We have an 837 with 64/12, with latest non-plus code (plus version doesn't fit in flash). You will be fine with 128/24 on the 877.
