Default ssh hosed after adding second tunnel to 506


running 6.3(3)

after adding a second tunnel on a crytpo map applied to outside I can no
longer ssh from the internet. I can however ssh to it via another box
on the outside int net.

any ideas?

Answer most likely lies in the match address for new crypto map policy.

the new crypto map entry sets up a tunnel between the pix outside and an
fe port on the gateway router (this was necessary to allow the vpnclient
users to pass traffic across the other tunnel on the pix to a remote
pix. the acl just covers the vpnclient addresses and the pix inside
lan. So I still don't understand how this would affect ssh access to
the pix outside int address.

We don't understand either, but you aren't giving us hard configuration
information to work with.

I would suggest that if you have a CCO account that you run your
configuration through the Cisco Output Interpreter at
http://www.cisco.com/go/tools . And if that doesn't show anything
useful, open a TAC case about it.

If you don't have a CCO account or SmartNet then you should probably
either give up or post a lightly-sanitized copy of your configuration.

That configuration looks okay from here.

What do you see if you turn ssh debugging on? And are you getting
log messages about traffic having been discarded because it needed
to be protected by IPSec?

nothing.


BTW, I've tried accessing both the outside interface in the clear and
the inside interface while vpnclient'd in to the gwrouter.

it was an ip inspect rule on the same interface as the tunnel. once i
removed that it worked. incidentally that was also dropping return
traffic to vpnclient hosts that were terminating on an outside int of
the router and then getting encrypted again on an inside int. of the
same router. still not sure exactly why the traffic was getting dropped
as I thought cbac and ipsec could co-mingle to a certain degree.
