i have 2 dsl connections, they will only work one at a time. the problem is that one web site i access can only accessed by connection 1 and a different website can only be accessed by connection 2. one of the connections is used for regular internet access also. so, with all of that in mind, how can connection 2 only access one website and connection 1 access everything else? Please help....
thank you,
CBlank

You can manually add "routing table" entries for traffic
you want to direct out of the alternate gateway.

First, use nslookup to find the IP address(es) for
the website name you are accessing. Just enter
"nslookup" at a CMD prompt, and then type the
name of the website. It will show you all the possible
IPs it can be (there may be just one or there may be several).
Then type "quit" to get out of nslookup. Don't close the CMD
prompt as you aren't done with it yet.

You then want to enter "route add -p" statements for
each such address to direct your traffic for that IP out your
secondary DSL connection instead of the default DSL.

So, assuming the website translates to IP 1.1.1.1 and
your alternate DSL's LAN IP is 192.168.1.254, you would
enter this from a CMD prompt:

route add -p 1.1.1.1 mask 255.255.255.255 192.168.1.254

Put in one of these for each IP if the website name shows more than one
IP translation. If you know what you're doing, you may be able
to just use a more open network mask, but if not don't worry about it:
1 IP == 1 route add

Note that this will direct ALL traffic for those IPs out the
alternate DSL, not just web traffic. The "-p" makes the route entry
stick around across reboots, but you might want to put these
commands in a batch file in case you ever lose the routes.

Also, if the site ever changes its IPs you will need to delete
the routes (route delete) and create different ones for the new IPs.

Best of luck

There's no reason it won't work if it is setup correctly.
Try "tracert <ip>" to see where the traffic is going.

RIP won't help because there's no reason to route
the traffic. Windows will only use one default gateway
as you've discovered.

I just discovered that the hard way as well. Thanks for the confirmation.
I was trying to route from a cable and a DSL as the backup / redundant but
it won't work. Thanks for the posting.
