Is the listening socket listening on port 10001?

I'm not aware of any limitations when it comes to connecting to computers on
different subnets using TCP! (UDP broadcasts are a different matter).

Maybe this is a network question, I don't know.
I have this weirdness with my socket class that is derived from
CAsyncSocket. 6 months ago I was able to connect to computers that are not
in
my subnet, however I was using port 80 to test, ie (www.yahoo.com:80). I
am
trying to connect to computers that are not on my subnet on port 10001 but
the OnConnect callback said it failed.
i.e. my IP 192.168.1.100 and I am attempting to connect to a computer with
a
fixed IP of 192.168.2.122.
Both computers have a subnet mask of 255.255.255.0, both computer do NOT
have a default gateway. I will have the two computers connected using a
crossover cable, if I need a gateway, what should if be for each computer?

I know it's not a router issue because i get the same results if I use a
cross over cable between the two computers.

I cannot seem to find the difference in my code, could it be because of
the
high port number?

Thanks in advance.
