how do I ping/ join a windows domain across pix ipsec
Posted by none22 on January 27th, 2004



I need some assistance. All I need is for one network to ping th
network of the other side through a pix ipsec tunnel. after the ping
i want one network to join a windows domain of the other pix.
help...and also, why can't i telnet to the outside int. of the pix.
thanks in advance.

To be able to join a Windows domain, you need a WINS server if the
two ends are in different subnets.


:192.168.0.0-->pix-->22.1.2.2---internet--33.1.2.1--Pix2-->10.1.1.1-->10.1.0.0
:and 10.2.0.0:

:PIX Version 6.3(1)

:access-list 101 permit ip 192.168.0.0 255.255.0.0 10.1.0.0 255.255.0.0
:access-list 101 permit ip 192.168.0.0 255.255.0.0 10.2.0.0 255.255.0.0

:access-list acl_in permit ip any any
:access-list acl_in permit icmp any any

icmp is a subset of ip, so that second line is redundant.

:ip address outside 22.1.2.2 255.255.255.248
:ip address inside 192.168.1.1 255.255.0.0

:global (outside) 1 interface
:global (outside) 1 22.1.2.3

You can't PAT to two different IPs. You should remove one of those
two statements.

:nat (inside) 0 access-list 101
:nat (inside) 1 192.168.0.0 255.255.0.0 0 0

:access-group acl_in in interface inside

Allowing all traffic from the inside to the outside is the default,
so you could do away with acl_in .

:route outside 0.0.0.0 0.0.0.0 22.1.2.3
:route inside 192.168.0.0 255.255.0.0 192.168.1.2 1

Do you have an inside router you haven't mentioned? That route inside
shouldn't be needed, as it is the same subnet as the static route that
will be automatically created when the 192.168/16 IP address is assigned
to the inside interface.

:sysopt connection permit-ipsec

:crypto map transam 1 match address 101

Okay, you should be able to ping host-to-host across the network,
provided the IPSec device at the other end allows it. You won't
be able to ping the IPSec device -itself- across that tunnel, though.
And they won't be able to ping your pix across the tunnel.
[That's because you haven't included the endpoints -in- the tunnel.]


:telnet 33.21.12.81 255.255.255.255 outside

:help...and also, why can't i telnet to the outside int. of the pix.

You can only telnet to the outside interface through an IPSec
tunnel. The remote address 33.21.12.81 isn't in the IPSec tunnel
you define via access list 101 -- only 10.1/16 and 10.2/16 .
[33.21.12.81 also isn't the remote peer, which you said was 33.1.2.1 .]

If you need to be able to get to the PIX remotely from outside the
tunnel, then you should use a 'ca generate' command, then
a 'ca save all' (important, don't forget that!), and then configure
'ssh' access.
