Helo all,

          Sorry for the very late reply. After setting
the MTU to 1350, the connection was fine for a couple
of days. So far i'm allowing ICMP ports 0,8 alone.
Since this issue is very important, i've changed my
entier settup. Once the things are fine then, I'll
update my firewall with ICMP request handling and
revert it back. Now I need a way to find out which
link is having lesser MTU problem. Is there is any way
to find it out?

TIA
John

As in, you are A, and B,C,D are all on the same
network?

If not, then it would still be the ICMP issue.  It
maybe that with the
other servers, the
default MTU is just fine, but somewhere between you
and this server
with the issue,
there is a link that cannot handle the 1500 byte
default MTU.

BTW, It is good practice to allow those ICMP types
and codes.  They
are part of the
actual function of TCP.

Thanks for the Reply. The client also running ssh
(OpenSSH_3.1p1, SSH protocols 1.5/2.0, OpenSSL
0x0090602f). But the problem is the same set of
firewall is running very fine with my other
servers.
