PIX 501 PPPoE w / static NAT loss of connectivity
I have a {should} installation very simple. PIX 501 with PPPoE on the external interface, 3 inside customers using PAT and 1 inside the client I am trying to use an address mapping static on permit communications with this host from the outside using a particular service. I did a lot of these before where there was an ADSL router in front of the PIX, but this is the first where I've used the PIX as the PPPoE client. When I use the static NAT for the single host it loses all connectivity beyond the PIX outside interface. When I get rid of the static mapping, through PAT very well. I spent many hours troubleshooting and control a lot of obvious things, but I am at a loss right now... unless it could be a problem with the IP address that has been assigned by the ISP for use with static NAT. Any thoughts on this would be greatly appreciated.
Thank you
Sorry, in your case that static would look like this because of the dynamic IP.
static (inside, outside) 23 interface 10.1.1.1 23 netmask 255.255.255.255

Hello
I have a pix 501.
It gets the IP address of the ISP using PPPOE.
If I have an e-mail inside server can I still have the email NAT for this device.
I did before NAT on mail servers where I have a breakdown of the intellectual property of PSI.
In this scenario, I have 1 IP (he doesn't) outside.
Can I allow other services too although I have 1 IP address
John
The config is OK, but it might be better to replace the fixed IP address in the access list and the staic by a dynamic.
1. you have configured:
outside_access_in list of access permit tcp any host XX. XX.XXX.XXX eq ftp
Access-group outside_access_in in interface outside
static (inside, outside) tcp XX. XX.XXX.XXX ftp ftpserver ftp netmask 255.255.255.255 0 0
2 - I would like to replace this with:
outside_access_in tcp allowed access list any interface outside eq ftp
Access-group outside_access_in in interface outside
public static tcp (indoor, outdoor) interface ftp ftpserver ftp netmask 255.255.255.255 0 0
The advantage of this configuration is that if the IP address changes NAT and access list won't automticly too.
3 - you need a CLEAR XLATE after have changed you the NAT settings.
clear xlate
Note that this will reset all connections.
4. - use a dyndns or no - ip client so that when you connect on the Internet you just have to know the DNS name, and if the IP address changes the client will update the DynDNS server.
See:http://www.no-ip.com/downloads.php
5. - are you sure that your ISP Internet service provider allows ftp, smtp, and http? Many providers to block the ports for non-commercial DSL connections!

Cisco PIX 501, offered a license based on the connection: 10 or 100 users. What that means (e.g. for a 10 user license):
-a maximum of 10 xlates in the nat table?
-a maximum of 10 connections in the table conn?
If finally we're true, a user can establish 10 outbound connections (from an ip address). Currently, other users cannot establish a connection outboung?
Thank you
Edgar
"User" is defined as follows:
-a sent or received traffic via the PIX in the last xlate timeout seconds (five minutes with 501 default config).
-has a TCP or UDP connection
-a a NAT session
-a a session to authenticate user
It is certainly not the number of connections, but basically, the number of unique IP addresses internal that have any number of connections through the PIX. The 501 will support up to approximately 26000 connections, but only 10 internal IP addresses could use those.
You can make a "host local sho ' on the PIX to see all the current"users. "

Pix 501 for Small Business SERVER 2003 configuration problems
I am new to cisco equipment. My company recently purchased a firewall of Pix 501 unlimited number of users, it is connected to an internet connection by cable with a dynamic ip address. Internet works fine and so the dhcp server.
I have a Windows 2003 Small Business Server on our network. I need to configure the firewall to forward ports on the SBS server for remote web workplace.
Also about a week ago I lost connectivity to the GUI of PDM via my web browser. Telnet and console work perfectly well.
I enclose my config file.
Any help will be appreciated. Thank you
Ed
FIRT off, you do not have a group-access instruction set for one of your ACL. This means that you have blocked all inbound traffic. You also have your incorrect static instructions. You can start by cleaning your config and enter the correct commands, you should be able to stick to your firewall config mode:
No list will host 192.168.1.1 acl-enabled access 192.168.1.1
no access list acl_outside not allowed tcp any any eq www

What ip you are trying to access your pdm of? the looks of configuration http correct, unless your coming to one other than 192.168.1.x ip address
Let me know if it works

I PIXA (192.168.27.0) PIXB (192.168.1.0) with a VPN connection. I want to PIXB network 10.10.1.0 NAT when it connects to PIXA, so that when I do a ' sh ipsec his ' on PIXA, it shows the remote ident as 10.10.1.0 instead of 192.168.1.0. I enclose my config PIXB. Does anyone mind overlooking it and tell me what I'm doing wrong? Thanks for all the ideas.
1. remove the "nat (inside) 0 access-list NO - NAT"
2. change acl 90 "access-list 90 allow ip 10.20.1.0 255.255.255.0 192.168.27.0 255.255.255.0.
3. edit the ACL on the other end as well.

VPN PPTP and PPPOE CLIENT ON PIX 501
Hello
Can I create a PPTP VPN and a client connection on a PIX 501 with a client to my ISP PPPOE connection. The PPPOE ip is dynamic and the VPN will be a static IP address. They gave me a username and password for VPN and PPPOE. Him also gave me an ip address for the VPN server.
Should that happen, it's that the PPPOE should connect to the VPN to work.
I can only get the PPPOE, but I don't know how to do this with a PPTP VPN set.

It is I'am using access list and groups wrong or am I wrong in PAT/NAT configuration.
Please advise...
Hello
I went through the ongoing discussion. The pix configuration should be fine for now according to suggestions. The problems seems to be on the server. If it is a new installation of windows, then there is an option not to accept requests that are not local network.
If you want to check if pix allows connections and then when you telnet to port 25 of the outside, just run the xlates control.
SH xlate and it should show you a translation for the inside host. More than a quick test if pix allows traffic is to check 'sho-outdoor access list' and see if the counters are increasing.
Hopefully this should help you.

I'm doing a static route to xxx.242.139.164 to 192.168.1.13 and open ports 25 and 443. I am at a loss for what I missed to make this happen. I would also like to open the ICMP traffic or at the least response to echo so I can test the IP addresses and that doesn't seem to work either.
PIX config attached .txt file.
Thanks for any help!
Hi Comoms,
This is your problem:
(1) here say you do not NAT traffic.
NAT (inside) 0-list of access inside_outbound_nat0_acl
inside_outbound_nat0_acl ip access list allow any xxx.242.139.160 255.255.255.224
(2) then you use it for the static NAT.
public static xxx.242.139.164 (Interior, exterior) 192.168.1.13 dns netmask 255.255.255.255 0 0
(3) it's totally fake, first u say don't not NAT traffic, try you NAT, it. How will it work?
(4) even if uou help with ACL, it won't work.
(5) Please check your routes n NAT ACL, NAT STATIC, once again.

PIX 501, 1 static IP, IP address dynamic 2. Mesh full possible?
I have 3 sites. All sites have PIX 501. Central site has a static IP, 2 remote sites a dynamic IP.
I have no problem with the connection to the central site by using their dynamic IP address in a remote star connection.
Is it possible for 2 remote sites communicate? There is data that must be transferred between remote sites. I read somewhere in cisco site web which its possible via mesh on request.
Does anyone have an example of configuration on a VPN Site to Site where the Central site has static IP and remote sites with a dynamic IP? Remote locations teaches a dynamic IP from remote sites to the central server.
Thank you.
With IOS as your hub and then the Yes rays, the rays can learn dynamically address other departments using the PNDH. This type of configuration is called Dynamic Multipoint VPN (DMVPN), you can read everything you need to know about this here:
http://www.Cisco.com/warp/public/105/DMVPN.html
Even with EzVPN (not DMVPN) the rays will not learn the address of other rays, all communication is always via the hub. Call another talks would work, but as I said, the packages will talk-star.

PIX 501 DNS resolution with static route
I use a pix 501.
I have an internal DNS server behind the pix that uses my DNS of the ISP servers to resolve external domains.
Now, I want to host a web site on the same server.
To allow external access to the web server, I add the following:
outside_in_http list access permit tcp any host A.B.C.D eq www
static (inside, outside) A.B.C.D L.M.N.O netmask 255.255.255.255 0 0
Access-group outside_in_http in interface outside
It is very good and allows web access. The problem is that the server is able to resolve DNS queries.
How can I allow my server to resolve DNS again securely. I guess it's pretty simple to do, but I'm having a lot of trouble to find the solution.
Thanks in advance
Dylan

Hello
I work to connect a PIX 501 VPN for a 3rd party hub 3015. The hub requires all traffic to come from a single source IP address. This IP address is assigned to me as z.z.z.z. I have successfully built the VPN and tested by mapping staticly internal IP with the IP address assigned, but cannot get the orders right to do with PAT in order to have more than one computer on the subnet 10.x.x.0. This Pix is also a backup for internet routing and NAT work currently as well for this.
I can redirect traffic to my subnet to the remote subnet via the VPN, but I can't seem to get the right stuff PAT to the VPN using the assigned IP address. If anyone can give me some advice that would be great.

Dave,
(1) get rid of static electricity. Use more Global/NAT. The static method will create a permanent
translation for your guests inside and they will always be this way natted. Use
NAT of politics, on the contrary, as shown here:
not static (inside, outside) z.z.z.z 10.x.x.50 netmask 255.255.255.255 0 0
Global (outside) 2 z.z.z.z netmask 255.255.255.255
(Inside) NAT 2-list of access 101
(2) the statement, "nat (inside) access 0 2' list will prevent nat of your valuable traffic."
Delete this because you need to nat 2 nat/global card. (as a general rule, simply you
If you terminate VPN clients on your device and do not want inside the traffic which
is intended for the vpn clients to be natted on the external interface).
(3) with the instructions of Global/nat 2, all traffic destined for the remote network will be first
translated into z.z.z.z. Then your card crypto using the ACL 103 will encrypt all traffic which
sources of z.z.z.z for y.y.y.0 24. This translation wil happen only when traffic is destined for the vpn.
I hope this helps. I have this work on many tunnels as you describe.

Add the following to the PIX:

This indicates the PIX around all ACLs for IPsec traffic. Now that your IPSec traffic is still subject to the standard rules of PIX, so launched inside the traffic is allowed to go in, but off-initiated traffic is not.

Hello
I am considering the implementation of a vpn pptp on win2k server behind a pix 501 firewall (+ nat) with only 1 static IP address. I will also have to have at least 2-3 Terminal Server client connected simultaneously.
The Terminal Server service will pass through vpn tunnel.
Can this be achieved? A local Tech told me that I need at least 2 IP addresses.
Thank you
Mike
For Terminal Server services, you can do it with just an IP address that is assigned to the external interface of the PIX, just create a static mapped port to port 3389 thru peripheral inward.
For PPTP, you must however an IP address separate, different from that assigned to the PIX outside the int. This is because PPTP uses two TCP/1723 and GRE protocols. You can create a static mapped ports for TCP/1723 through the PPTP server, but you can't do it for the GRE. This is because GRE is not a TCP/UDP protocol, it is located just above IP and has therefore no port number to map through. You need an IP address unique address and card. You config should look like this:
list of allowed inbound tcp access any host 200.1.1.1 eq 1723
list of allowed incoming access will any host 200.1.1.1
Access-group interface incoming outside
public static 200.1.1.1 (indoor, outdoor) 10.1.1.1 netmask 255.255.255.255
where 200.1.1.1 is your second (different from the PIX off int) routable IP address 10.1.1.1 is your PPTP server inside
If you only want to use an IP address, why don't the PIX not set itself up as a PPTP server and put an end to your connections on this. The PPTP client end simply on the PIX outside IP address, and you will not need all the others.
See http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a0080143a5d.shtml for more details.

Cisco PIX 501 to Cisco 3005 concentrator via remote access
Hello people,
I need your help.
We got a Cisco PIX 501 in one place and this pix is configured for pppoe connection. The pix connects to internet via the pppoe client. an official ip address ping works well.
So what I want to do is to establish a tunnel von between this pix and a cisco 3005 concentrator.
But I failed to establish it.
Here are the pix config. the acl? s are only for the test and will be replaced if it works.

the hub, I created a user pixtest, a group vpntest and I? ve created the rules of the network for example to what server, users behind the pix will be able to access.
And that? s all.
I couldn't send you exit pix or hub because I don't have an error or a message that the tunnel will be established.
What can be wrong?
Thanks for the replies
This configuration example shows how to create an IPsec tunnel to a computer that is running the Client VPN Cisco's (4.x and later versions) to a Cisco VPN concentrator 3000 to allow the user to safely access the network inside the VPN concentrator.
