Subject: [OS2Wireless] default route problem

Interesting, Dave, as I didn't even know that the OS/2 stack supported 
multiple default routes (in NetWare, this is known as Multiple Default 
Gatewayt with Dead Gateway Detection). Here's a bit more from the eCS 
1.2 help docs:

        *OS*/*2* TCP/IP provides support for default route recovery (RFC
        816) by allowing you to specify multiple default routes in the
        \MPTN\BIN\SETUP.CMD file. If the current gateway should go down,
        the stack selects the next preferred default gateway from the
        list in SETUP.CMD and tries to maintain the connection. When the
        new gateway has successfully routed 25% of the TCP connections
        that use the default route, the new gateway is made the default
        gateway for the entire machine.

        The default gateway IP addresses are entered in SETUP.CMD in the
        order that has the least preferred gateway as first and the most
        preferred gateway as last. To implement default route recovery,
        the **multidefrt** flag must be set to ON, which is the default
        setting. You can turn off this L:\INFO-Misc\LibPathflag using
        the inetcfg.exe application.

        inetcfg -s *multidefrt* 1 # to turn it ON
        inetcfg -s *multidefrt* 0 # to turn it OFF

        Example

        In the SETUP.CMD file

        route add default 9.1.2.3 netmask 255.0.0.0 #this is the least preferred gateway
        route add default 9.1.2.4 netmask 255.0.0.0
        route add default 9.1.2.5 netmask 255.0.0.0 #this is the most preferred gateway

I'll have to try this a bit.
