Re: Any Way to Lock TCP Traffic to One Router



I'm pretty sure the Windows box will always use it's configured default
gateway. The routers should be setup in a redundant fashion such as HSRP or
GLBP. It does not make sense to have two separate routers doing the same
function (providing gateway services), they should be configured as a
redundant pair. That keeps all the administration off the servers (ie
multiple routes). The return path should be through the same gateway device,
but I'm making an assumption on your network. If you need a 'hard' answer
you need to post more info.

Say I have the following machines and network:

- Computer A is on Class C 10.10.10.0

- Computer B is on Class C 10.10.20.0

- The two networks are joined by two routers, for fault tolerance.
Router 1 might use 10.10.10.1 and 10.10.20.1 for its interfaces, and
Router
2 might use 10.10.10.2 and 10.10.20.2 for its interfaces.

- Computer A and Computer B are Windows 2000 or 2003 computers that each
are
configured to use the two routers with equal metrics. Computer A would
be
configured with equal metric routes to 10.10.10.1 and 10.10.10.2.
Computer
B would be configured with equal metric routes to 10.10.20.1 and
10.10.20.2.

Given the above configuration, is there any way to lock a TCP connection
between Computer A and Computer B to a single router? In other words,
is
there any way to have the receiving end of a TCP connection use the same
router for the return traffic that was used to send to that computer? I
don't want fragments of connections going through different network paths.
I'm hoping that either by default Microsoft is routing the return path to
the return traffic to the same router used to send, or that alternately
this
behavior can be configured.
