[cvsnt] Connecting to CVSNT over a router

[Sekar]

Hello:
    I am using cvsNT 1.10 on windows nt server for about a year.  Recently
we put a new upgraded CVS server to 1.11  on windows 2000 machine.   Both
machines on the same network segment(for example x.y.1.1)   If I connect
to those machines from the same segment (x.y.1.2)  I am ok.   I can also
connect to windows nt/cvs1.10 machine fine from  a different segment(for
example x.yyy.1.1)   But when I connect to 2000/cvsnt 1.11 machine from
different segment(x.yyy.1.1)  I get a cannot connect to host.
    Our Tech support claims that cvsNT must be using a non standard
protocol thats not supported by our router.   Now I dont know if cvsNT is
using a differnt protocol.   I am using eclipse as my cvs client.   
    I searched the newsgroups, I dint find any issues related to this (may
be i overlooked).   If any one knows the solution, can you please share it
with me.

Thanks
