two connections


hi,

i understand that this may have been asked before, but is there anyway to connect to two gateways on a fedora core 1 box. i have two internet connections due to 2 joined houses. im fine setting up a normal gateway but this is what i hoped to do.
(ive attempted to draw it out in order to try and make it easier to understand)

----------------------------------------------------

Code:
Internet                              Internet
    |                                     |
Gateway                                Gateway
2 nics                                 2 nics
(external ip)                       (external ip)
(10.15.121.11)                      (10.15.121.12)
    |_____________________________________|
               |                    |
            Gateway            Workstation
         (10.15.121.21)      (10.212.78.199)
         (gateway =            (gateway =
         10.15.121.11 &        10.15.121.21)
         10.15.121.12)
-----------------------------------------------------

could someone please let me know if this kind of setup (or an alternate one that will achieve the same thing) is possible, and if so how i would go about it. thanks very much for your time,
dylan

erm ok.... so firstly i asume that Gateway at the bottom is actually a workstation?

why are you using the network addresses that you are? if this some odd bridging going on? what is the netmask of the network you are using? normally forthe 10 network it's 255.0.0.0, but i'd strongly suggest that by converting everythign internally to 192.168.0.0/24 you'll get a lot lot more clarity over the network.

how do you propose to physically connect these two networks? do you want two seperate networks that route together or do you just want a single network with two internet connections on it?

what level are you actually asking for advice about? are you plannign on just running a cable between the two lans, a wireless bridge that you are already comfortable with?

As you don't have a single router to control the two internet gateways you aren't going to really be able to load balance the connections if that's what you want. you could nominate one box as the primary router but it's not going to be a particuarly nice solution. details of load balancing are on lartc.org as well as many other cool networky things.

hi,
no i dont have any kind of network bridging happening, its just the 1 network. the gateway at the bottom was meant to be a gateway, although im not sure if it would actually work that way, i was just throwing out ideas. if it really confuses you, think of the workstation with an ip of 10.15.121.31 not 10.212.78.199. what i want to do is to see if it is possible to 'double the bandwidth' of my internet connection by actually using two different connections, so basically like load balancing. i originally got the idea when i saw a friends isdn connection where he plugged in two lines to the modem, resulting in twice the bandwidth. if i was to use load balancing, how many interfaces would i need?

there is no particular reason why i decided on the 8bit addressing, but my subnet mask is 255.0.0.0. also, what do you mean by more clarity?

thanks,
dylan

ok, well if you were using this internal gateway as the router for the workstation then as above, check lartc.org for the kind of things you need to configure on that router, to equally balance the two connections.

what your friend did with 2 isdn lines is not anything related to this at all really, just one of the things that ISDN can do.
