Limited SMTP outgoing with PIX
I want to restrict SMTP out to our mail server in the DMZ. We have a PIX 515E between our internal network and an external router 2650. I want to restrict all machines except the sending SMTP outgoing mail server but always allow SMTP to the mail server. As the PIX only supports the inbound ACL that I have to configure the ACL on the external router or is there a way of WHAT PIX for this? Thank you.
If the SMTP box is on the DMZ of the 515e int, you can write an ACL for indoor int the 515e that blocks all the tcp any any EQ 25.
That's assuming that you do not use SMTP from the client PC to the e-mail server in dmz, if you start the acl by a statement authorizing the smtp to smtp server traffic and the following statement must be a refusal all to smtp 25.
Finally, if you do not have an existing ACL inside int, probably have an ip address allowed any any statement to permit all other traffic to proceed

Hi, I am trying set up port forwarding on a PIX 515 running version 6.3 (3) and nowhere fast.
The idea is to redirect the traffic from port 25 to port 2525 and the static command, I tried is as follows:-
static (inside, outside) tcp 25 X.X.X.X Y.Y.Y.Y 2525 netmask 255.255.255.255 0 100
Where X.X.X.X is a public address and Y.Y.Y.Y is a private address.
Also, I added a line of the access list to port 25 for incoming host X.X.X.X.
The redirect does not work. I even went as far as the test on a web server, forwarding port 80 to 8080, but traffic is sent to port 80, regardless of the static command.
Can someone please tell me what I'm doing wrong? My understanding is that the port redirects were possible with the later pix 6.0 or version software.
Thanks in advance,
Rick
No sweat. I almost always overlook the simplest things so when someone else has a problem, I start easy and move up. Usually solves the problem more quickly.
As for your other question, Yes, it is normal. Remember that static is bi-directional translations. Thus, when you added the port information in the static command to the SMTP server, the PIX only knows now to translate packets from TCP/2525 (I think that's how you had it). When your mail server tries to send outgoing mail, the source port will be an ephemeral port (IE not 2525 probably). So, I usually people do something like this:
static (inside, outside) tcp 1.1.1.1 25 10.1.1.1 2525 netmask 255.255.255.255
NAT (inside) 2 10.1.1.1 255.255.255.255
Global 2 1.1.1.1 (outside)
It takes care of everything in both directions of the 10.1.1.1 host (for example).
Hope that this helps explain the issues. Good luck.

802 1 q tagging with PIX 6.3 (1)
Someone uses VLAN tagging with PIX 6.3 (1)? I could make an ethernet (eth0, for example) as port trunking to carry vlan2, vlan3/vlan4. But the PIX does not define ethernet as an access port 1 belongs to the vlan 2. Or if I try to assign ethernet3 belongs to vlan3, it would be rejected by the PIX also.
I thought that the concept of PIX to award port trunking and a VLAN access port must be the same happening with catalyst, but it looks like I'm wrong. Anyone can point the right direction?
Best regards
Engel
Engel: Configure the VLAN on the PIX is not the same what to do on the switch. The PIX interfaces are not configured as 'trunk' or 'access' ports ports. With the PIX, you can assign a vlan is a physical interface - or assign a vlan as a logical on a physical interface interface. And vlan is limited to a single PIX - physical or logical interface, here's an example configuration:
interface ethernet1 100full
physical interface ethernet1 vlan50
logical interface ethernet1 vlan60
logical interface ethernet1 vlan70
logical interface ethernet1 vlan90
interface ethernet2 100full
physical interface ethernet2 vlan20
interface vlan1 ethernet2 logical
logical ethernet2 vlan30 interface
logical interface ethernet2 vlan40

is compatible with PIX SSM - 4GE manufacturer?
proposed replacement of PIX - 1FE is SSM - 4GE. This means that it is compatible with PIX?
No it's not. The PIX now being EoS, assume you have / will upgrad to the ASA.

Is it possible to set up SMTP authentication with the vCSA 5.5?
Hello.
I have a vCenter Server Virtual Appliance 5.5 and SMTP server that requires SMTP authentication with port 587.
I found the advanced settings "mail.smtp.port", but I found no parameters as 'mail.smtp.username' and 'mail.smtp.password '.
Is it possible to set up SMTP authentication with the vCSA 5.5?
Best regards.
No, can't be done.
Set up a separate SMTP relay that would make authentication for you. as explanation then post

Limitations of architecture with replication of VM with physical RDM Mode
What are the Limitations of Architecture with replication of VM connected with physical RDM Mode in vsphere replication. Why VMware does not support this?
I will add some colors to the response of GS. A particular interest with regard to the physical path RDM (pRDM) works, summarize these two chips of the article:
- Physical mode specifies minimal virtualization SCSI of the mapped device, allowing greater flexibility for SAN management software.
- VMkernel passes all SCSI commands to the device, with one exception - the REPORT LUNS command is virtualized, so that the VMkernel can isolate the LUN to the virtual machine owner. Otherwise, all the physical characteristics of the underlying hardware are exposed.
There is an integrated in vSphere vSphere (RV) replication agent that has several functions. In particular, she keeps track of the Scriptures to the virtual machine. When a replication cycle occurs, the changed data is replicated to the target location. The VR agent should be able to 'see' These Scriptures to follow. Given that the physical mode all SCSI commands directly to the device, the VR agent is unable to follow these changes for replication.

SMTP outgoing on several accounts FAIL
I'm new to Thunderbird. With the keys v 31.0
I have several e-mail accounts hooked, all with separate outgoing SMTP defined. They all work... and then they don't.
What is happening is that no matter what email account I use to send an e-mail, the SMTP protocol changes by default, that will not work unless I'm on default e-mail account.
I'm going on the specific account settings, and of course the SMTP is by default off. I have change. I can send my email.
I'm going to send another and this process repeats.
It is incredibly difficult to have specific manually the SMTP protocol every time I want to send an email.
Why - what is forgetting its individual account settings?
How can I fix it?
You use or you use multiple identities for accounts?
Each account can have multiple identities using a specific SMTP server each. Make sure they are on what you want.
There is full information on this configuration to this MozillaZine page.

Problem of recovery of password with pix 501
Hello
my organization uses a firewall 501 pix with version 6.2 of the software. After I lost the password I tried earasing using the faq provided on this site (using the file np62.bin through a TFTP server).
Unfortunately, I can not connect using the password default "cisco."
Thank you
Raphaël Cohen, University of Tel Aviv
Hello Raphael,.
You need to connect to the PIX via the port on the PIX console. If you deleted the passwords, then (as mentioned before), there is NO password to access privileged EXEC access just don't hit back, now, you will need to configure a password to "enable" with command > pix # enable password - the password is case-sensitive and can be a combination of characters and numbers the length of the password is limited to 16 characters.
You can now set access telnet as well i.e. config mode > pix (config) # telnet [masque_sous] [interface_name]
example: (in config mode) telnet 192.168.10.10 255.255.255.0 inside
Good idea to use the static IP address for the above, makesure to save your config with cmd: write memory
Hope this helps - Jay
PS. Thanks to vote this post if it helped you so that other members can use it if they have the same problem you have - that helps! Thank you.

Problem with PIX 501->; L2L 1721 VPN
I am setting up a site to site vpn according to the http://www.cisco.com/en/US/tech/tk583/tk372/technologies_configuration_example09186a008051a69a.shtml.
I want to connect 192.168.105.0/24 and 192.168.106.0/24.
PIX01 is 192.168.106.1, with dynamic external IP (B.B.B.B)
RTR01 is 192.168.105.1, with dynamic external IP address (I'm just using DHCP current address of the ISP as A.A.A.A in the config of PIX01 - this is a temporary application, not critical where I can update the address if necessary)
It seems that the VPN tunnel is established but traffic does not return the router to the pix. I temporarily hosted all of the traffic on indoor/outdoor PIX interfaces (and icmp).
If I enable icmp debug I see ping requests from the client to 192.168.106.100 internal interface of the router (192.168.105.1), but no return icmp:

ISAKMP uses UDP/500 and it is true he helped through phase 1 being upwards (QM_IDLE).
IPSec uses ESP or UDP/4500, and this is what must be authorized by the FW.

Remote VPN with PIX without access to the local network
Hi @all,
I ve running into problems and I have not found any solution. Can someone check my config?
Facts:
PIX 501 6.3 (3)
4.04 VPN client
Wanted solution: access to HO via VPN
VPN tunnel will be established, I get an IP address, but I can´t the systems behind the pix and the pix of access itself.
To the VPN Client Staticts, I see outgoing packets, but no entrant (if I send a ping to peer behind the pix)
I hope someone can help me
Attached is my config:
PIX 501 and 506/506e pix are not supported in v7 due to the fact that the cpu is not able to deal with the extended features of v7.
PIX 520 is not supported I guess it's because of the fact that the model is discontinued.

SMTP problem with the recipient's address
Hi, I made a copy of the function of SMTP Email message send to use it with another port smtp (as 587). Everything works well when the recipient's address is like [email protected] or any what normal address. The problem is when I'm trying to use this function to send an e-mail to an address like [email protected]. Each email to the address of the company is like the second example. Does anyone have an idea to solve this problem?
I had the same problem with my mail server @msu.edu.
The problem is that many companies use TLS or SSL security settings.
There are ways around this problem.
I have attached a VI that should work for you.
I can't take credit for the VI, it was given to me by a person on the forums.
I've just modified it a bit.
Edit: If you look at the block diagram, upward, there is a node to invoke.
It's for "SMTP Client", and the element is "host".
You will need to change that to 'mail.msu.edu' to any server used by your company.And you may need to change the port as well.
I also customized the VI icon, but you can leave if you like it

4240 IPS blocking queries with Pix 515E
I have activated the lock on the 4240 and put locking as our Pix 515E. When I look at the Configurations of Signature quite a few Signature Actions are set to alert only produce. If blocking is enabled you also go and the Actions of signing the Deny value or TCP Reset? So far my attackers show dosen't IPS refused and he detected the high level of traffic which I assume must now be blocked. Thanks John
Yes, go under the signatures that you want and enable blocking for them as an action. Globally blocking configuration (setting the blocking device, the interface, the connection of the device information, etc.), does not actually blocked on the sensor itself, we must still go and activate the blocking of this particular signature. When this particular GIS fires in the future, the sensor it will block on the device that you configured.
Be very careful with blocking, the reason that we're not blocking simply all the signatures, it is that it would be very dangerous to blindly add access lists to a device that will stop traffic. You must first make sure that you don't get any number of false positives on the signatures and end up blocking valid traffic. In addition, on a busy sensor you could easily overrun detector and locking to writing and deleting 1000's of top access lists. And finally, although probably not, blocking can even be used as an attack denial of service, where an attacker, if they know what signatures you block, can usurp packages past your sensor so that it denies traffic to our legitimate guests.
You have to look at what signatures you really want to block, and then enable blocking on them individually.

http A.B.C.D 255.255.255.255 inside
A.B.C.D is the ip address of the host from which you are trying to reach the pix with the pdm.
If you're still having problems after the addition of these two lines, you might have a look at this page:

You can use one card encryption on an interface, but you may have within your crypto card so your config sequence numbers

card crypto mykink1 2 the value transform-set "new transform set.
card crypto mykink1 2 security association second life "number of seconds.
You must complete the good values in the "" marks.
Note that the sequence number is incremented by 1 in your first entry for 2 in the second entry.
You can specify the duration of security association in the crypto map config that overrides the global settings.
Add this config should not affect your existing tunnel.
