How to combine 3 connections cable+dsl+sat and host

| Currently my work is using 2 bonded t1 lines at 3mb for a office of around 20 people. The lines are shared with the phones and so the speeds vary throughout the day and can sometimes be pretty slow.
We are looking to save some money on internet prices so we might switch t1 providers or look for an alternative solution. I was wondering if it would be possible to use 3 connections, cable modem, dsl and satellite for triple redundancy. I have heard of people doing this with 2 connections with a dual wan router.
Is there a cisco router anyone can recommend for this setup with 3 ethernet ports. It doesn't matter if the connections are bonded as long as failover works from cable to dsl to satellite as a final resort.
We were also considering hosting a small website inhouse. I know we would need a static ip for the hosting. Is there a way to set it up so if the primary cable connection with the static ip went down the site would still run off the secondary static ip on the dsl connection?
Any ideas or links on the best way to setup something like this are appreciated in addition to any hardware recommendations for a router.

| What you are looking for is called LISP, search for cisco and LISP..
If you need someone to tell you more about it, I can recommend you a consultant that gave me(and lots of other techies) an great speech about it recently.

| thanks for the info, i was thinking of bgp multihoming but lisp looks a good replacement. anyone know of the cheapest router i could get on ebay to support 3 connections with either lisp or bgp?

| Get a used Dell or something and use linux to do this. Multiple nix cards can be used easily. I have read many articles on people doing this with a simple linux box. I don't have any bookmarks however google should be able to help you.

| I probably would try something like that if I was doing it at home but they wouldn't want another box to manage at work.
Has anyone done something like this before and could give some insight. I have read through a bunch of articles and forums on google about the theory of setting this up and misc chat but can't seem to find a step by step guide or something close that isn't 5 years old.
If we decided not to host on the connections and just had the cable and dsl connections without static ips, would we only need a standard dual wan router for failover?

| Hi,
i have done this for 2 companies and also my connection at home with multiple WAN failovers. Using Ubuntu + Zentyal will work. Setting up is abit tideous but once you get it up it is stable.
Also you can look into buying routers that DDWRT firmware supports. It comes with a built in failover.

| Our company owns an ISP on a military base in Afghanistan. We have three satellite dishes each with a single IP on the WAN interface and the rest of the network is NAT.
The device we use is a Cisco/Linksys RV016 multi-WAN router. It is very easy to setup and very simple to manage through the GUI. The retail cost is around $400.00.
I'm not sure why you would want to use a satellite uplink if you're in a place where cable and DSL is available. Satellite transponder capacity is very expensive ($8000 or so per Mbps, per month) so unless you're paying this much for your bandwidth chances are you're on a 10:1 contention ratio or on a Fair Access Policy (you get capped off if you exceed a daily transfer limit). Your latency will also be quite horrible, and in many cases your uptime will be less than optimal.

| Thanks for the feedback guys, I'll check out zentyal but really like the rv016 router and will probably go that route. We won't be getting a satellite for the office but just wanted to know if it could also be combined in a failover situation. I'll probably try out a cable/dsl combination and see how failover works at home with the rv016 before making any recommendations. I wanted to know more about the satellite to do something similar to your situation using 2 consumer satellite packages for a remote cabin location.

| the RV series linksys dual-wan routers are fairly decent but for some reason they slow down after long uptimes (magnitude of several months without reboots) ..i dont know if this has been fixed on the latest firmware.
But for that same budget you can also look into soekris or ALIX boards with pfsense. It can do BGP (which the RVs cannot do), load balancing, vpn, etc. etc. ..you can even installa hardware encryption card to offload your cpu intensive vpn sessions.

| You have any model numbers you recommend for the soekris or alix?

| Soekris Net5501
or
ALIX2D3
hardware security accelerator:
Soekris NetVPN 1411 (mini PCI)
both will run off a CF card (pfsense image); Soekris is a more pricier than the ALIX. As per thruput, i think they rated this at less than 50 Mbps (of course, your actual pps will determine final thruput and and other cpu load like VPN, dynamic routing protocols, amount of firewall rules, etc.)
