Using two broadband links

Discussion in 'Home Networking' started by fredbloggstwo, May 1, 2005.

  1. Hi all,

    here's a nutty one I need some help on.

    I am trailing two broadband connections on different telephone lines. Each
    has its own modem which presents an Ethernet interface and each modem path
    then goes through a router/firewall. What I want to do is to connect both
    up on the same network, but use one for browsing from IE and the other for
    e-mail using Outhouse Express. The clients are all WinXP connected by a
    switch.

    Any ides about how to achieve this?

    Thanks for any help, Mike

    Should be quite easy. I've done that (with three routers, two ADSL
    and one ISDN). In my setup I have router A as 10.0.0.100, router B
    as 10.0.0.200 (no need for any other info to complicate matters :)

    In an MS-DOS window
    1) use 'nslookup'
    enter each of the mail servers you wish to use, and note the
    IP address(es) which are reported.

    2) for each IP address, enter
    route add <server IP> <gateway IP>

    so you might enter route add 193.71.199.94 10.0.0.200

    To make a setting which will continue after a reboot, use route -p add ...

    You can use 'route print' to check the entries

    It is possible to do something more flexible with a mask, so you could
    set up access to a series of servers using something like

    route add 212.159.2.0 mask 255.255.255.0 10.0.0.200

    to force 212.159.2.1 to 212.159.2.255 to go via router 10.0.0.200

    Forgot to mention I had set the default gateway as 10.0.0.100 and I don't
    use DHCP... I set the DNS entries myself to servers one on each ISP (or
    some other) and route them permanently so I can just change the 'default
    gateway' on XP to force the majority of traffic onto one particular link.
    It's quite easy to fill one link with a newsgroups binary download, and
    keep browsing/other traffic on the other, in much the way you plan to do.
