RE: [TCLUG:18277] firewall question

You closed off too many ports.  SSH often tries to open an incoming socket
around 900 to 1024.

Subject: [TCLUG:18277] firewall question


I've been working on closing up my external connection a bit and I'm seeing
some odd behavior now that it's closed down.  If disallowed any connections
to
privilaged ports, except the few services I want people to get at, ssh, www,
etc.  Now if I ssh from any machine that is masquerading through the
firewall,
all is good.  However if I ssh from the firewall machine to anywhere outside
I
can't get it to connect.  When I turn on logging and look in my messages log
I
see that the machine I'm sshing to is trying to connect to the firewall on
ports 1021 or 1022.  Both machines are using ssh1 protocol 1.5.
