Help with Gateway switch script

[AIM Systems]

Hi all,

I'm hoping someone wiser that me can shred some light on this problem.

We have 2 internet connection into the office, I want to write a default gateway switcher script.

For day-to-day stuff we have a very high speed but capped DSL line.

For downloading large files and less important stuff, we have a slower speed unlimited line.

I'm trying to write a script that goes like:

if ([find_current_gateway] == 192.168.0.100) then
    REM change to slower DSL
    route change 0.0.0.0 mask 0.0.0.0 192.168.0.200
    echo Gateway is now [find_current_gateway]
else
    if ([find_current_gateway] == 192.168.0.200) then
       REM change to faster DSL
       route change 0.0.0.0 mask 0.0.0.0 192.168.0.100
       echo Gateway is now [find_current_gateway]
    endif
endif

Does anyone know the DOS command (or group of commands) to return just the default gateway [find_current_gateway]?

'netstat -nr' returns far too much information
