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
On your IP set dns to 67.38.230.69, then ping www.yahoo.com server from guest... what resovle?

PIX 501 for Cisco 3640 VPN router
-Start ciscomoderator note - the following message has been changed to remove potentially sensitive information. Please refrain from publishing confidential information about the site to reduce the risk to the security of your network. -end of the note ciscomoderator-
Have a 501 PIX and Cisco 3640 router. The 3640 is configured for dynamic map for VPN. The PIX 501 is set to pointing to the 3640 router static map. I can establish a tunnel linking the PIX to the router and telnet to a machine AIX on the inside network to the router. When I try to print on the network of the PIX 501 inside it fails.

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.

Slow DNS resolution by the router
I'm setting up Outlook 2016 with an outlook.com account. It times out when it searches for the site.
I unplug the router and plug the modem directly on my computer. Try again.
It does not expire. It is outlook.office365.com without problem.
Are there settings, I can check in my Netgear NETGEAR WNDR4300
I put in place using the wizard implementation. The DNS setting is get automatically from ISP.
The IP address is dyamically get from the ISP.
Run a DNS bench mark utility (there are many freeware out there) to find the best and fast DNS for you.

When I first bought a PS3, I needed a router to access the internet for my PC and my PS3. It worked fine for several months and then one day, that my router is no longer me connected to the internet. Currently I am connected to the internet directly from my modem which means that it is not my ISP that has the problem. When I connect the router it says that there is some sort of DNS error. Help?
What is the model of the router?
Are you on the computer or on the... PS3 DNS error ?
On the computer, click on start > all programs > Accessories > guest... A black box will appear (command prompt)... In the command prompt window type ipconfig and press "Enter"... Look for Ethernet adapter Local Area Connection address IP, subnet mask, and default gateway... IP address must be 192.168.1.x, subnet mask: 255.255.255.0 default gateway: 192.168.1.1 (assuming that your router is 192.168.1.1)...
If you get mentioned above IP address, a subnet and address the gateway then you ping the gateway, type ping 192.168.1.1 and press ENTER... If she gives you ask has expired, and then disable any firewall, the security software on the computer...
If you get 4 replies then type ping 4.2.2.2 and press ENTER, if you get the request exceeded, then you must update the firmware on your router...

DNS resolution with 2 domains?
Hello
We have a constant VPN connection to our parent company. I can ping to IP addresses no problem. Since then, I made some changes to our DNS server so that we can resolve their addresses. I have added a conditional forwarder for their area, which works very well.What I want to know is, is it possible to configure our DNS server so that I can resolve the addresses without using the FQDN? Example:We are Domain1, the parent company is Domain2.If I ping Server1 (FQDN Server1.Domain1.com), our DNS server will resolve it for us, and it will ping successfully.If I ping Server2 (FQDN Server2.Domain2.com), it will not be solved.Server2.Domain2.com ping resolves the address.
Basically, I would like that our DNS server to try to resolve the address. If it does not, check the server DNS Domain2. Is it possible, without questioning their DNS server for internet addresses (google.com, etc.)?Thanks and greetingsHello

PIX 501 & VPN Client unable to ping or encrypt traffic?
I'm new and I work on my CCNA. I have a Setup pix behind a dsl with NAT router that I can not turn off. I create a pin hole for IPSec traffic to port 500 to my pix off if. I can connect correctly the Client VPN software. I think I establish an IKE and IPSec tunnel very well. I used the wizard to configure the VPN. I have a pool dhcp which issues an IP address correctly, and user group with set password. There is no site-to-site VPN, the network is a network of peers without any DNS or WINS server on the local network. I'm lost, frustrated and tired of 45 minutes of driving on this site whenever I want to try to set up a new configuration. It is essentially a off the pix of the box. There not here all configurations at all really. Here is my config.

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.

I was training establishment of a static routing on three routers r2 (2600xm) connected to r1 (2600xm) via maps module T1 on the serial ports. connected to r1 is a router 2500 old called PC.
I removed the static routes off r2 and PC but when I get to r2 I connect to 2500 another console cable that I use to access a server I get the above error. all IP addresses are just generic subnets that I created to play with static routing. I can't remove someone has any ideas?
you use the subnet mask different than the one you used. According to the route table entry mask is 29
Try this,
1] r2 (config) #no ip route 172.168.0.0 255.255.255.248 192.168.2.2
or 2] another easy method would be to check the working config and copy stick with 'no' at the beginning.
See the race | include the ip route
Copy the static route statement and paste this what with 'no' in the global configuration and check the routing table.

Place a FIOS for VPN router behind PIX 501
I have a Verizon FIOS internet connection and one of their routers wide wireless broadband, and this is a configuration of base completely... their router DHCP and firewalls, and the connection has a dynamic address. I would put the PIX 501 behind the Verizon router as one of its clients and make the VPN PIX of other PIX 501 at other locations, such as my entire network has access to remote networks.
Is this possible, and if yes, any who could some suggest configurations (how to address internal and external, static routes ports that may be required somewhere, etc.)?
Thanks for any help.
When installing my FiOS, I had already asked that it be installed on the Ethernet cable. Don't know they need to do something for you to spend the coax to Ethernet.
The best way to test it would be to find the Media Converter (follow the coaxial cable between your FiOS router to the demarc and there should be a box with a coaxial port, some phone Sockets and an Ethernet port). If you unplug the coaxial cable and plug a laptop computer on the Ethernet port, see if your laptop takes a public IP address. If Yes, then you just have to run to your PIX501 Ethernet cable and you should be ready.
Just to note that Verizon, according to your region, reserved DHCP assignments. This means that you may need to call Verizon and ask them to release the previous assignment of DHCP-MAC addresses. I had this happen recently. They must release the assignment then your PIX will pull a new IP address and they will book your new IP - MAC address assignment. They do this to speed up the connection to a cold start time on the router.
Basically, they are filtering by MAC address, but rather through a sticky ARP where they clear the entry, and then the next device that connects records his MAC address and then only that device is permitted to connect to this leg of the cable. So there is a bit of work you have to do, but the most difficult part would be sitting on hold waiting for a tech, if you call to Verizon.

PIX 501 and VPN Linksys router (WRV200)
I inherited a work where we have a Cisco PIX 501 firewall to a single site and Linksys WRV200 Router VPN on two other
sites. Asked me to connect these routers Linksys firewall PIX via the VPN.
According to me, the Linksys vpn routers can only connect via IPSec VPN, I'm looking for help on the configuration of the PIX 501 for the linksys to connect with the following, if possible.
Key exchange method: Auto (IKE)
Encryption: Auto, 3DES, AES128, AES192, AES256
Authentication: MD5
Pre Shared Key: xxx
PFS: Enabled
Life ISAKMP key: 28800
Life of key IPSec: 3600
The pix, I installed MDP and I tried to use the VPN wizard without result.
I chose the following settings when you make the VPN Wizard:
Type of VPN: remote VPN access
Interface: outside
Type of Client VPN device used: Cisco VPN Client
(can choose customer of Cisco VPN 3000, MS Windows Client by using the client MS Windows using L2TP, PPTP)
VPN clients group
Name of Group: RabyEstates
Pre Shared Key: rabytest
Scope of the Client authentication: disabled
Address pool
Name of the cluster: VPN - LAN
Starter course: 192.168.2.200
End of row: 192.168.2.250
Domain DNS/WINS/by default: no
IKE policy
Encryption: 3DES
Authentication: MD5
Diffie-Hellman group: Group 2 (1024 bits)
Transform set
Encryption: 3DES
Authentication: MD5
I have attached the log of the VPN Linksys router VPN.
This is the first time that I have ever worked with PIX so I'm still trying to figure the thing to, but I'm confident with the CCNA level network.
Thanks for your help!
Hello
Everything looks fine for me, try to have a computer in every network and ping between them. Check the newspapers/debug and fix them.
Let me know.
See you soon,.

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.

Fixed DNS does not not on PIX 501 6.3
Hi all
I'm running a PIX 501 FW and all is well except for one thing. We have a DNS on the inside and the docs setting of dns correction should automatically translate a records so that they have IP addresses 'outside' from the outside, even if they are actually configured on the DNS server with 'inside' IP.
However, it does not work. If I for example. query the DNS server for ns.my.com it returns 10.195.0.1 and x.x.x.x not as I expected.
Is my wrong setting or not working at all?
Excerpt from config:
fixup protocol dns-maximum length 2048
public static x.x.x.x (indoor, outdoor) 10.195.0.1 netmask 255.255.255.255 0 0
Hello
I don't think that is what dns fixup is for.
Try this
public static dns netmask 255.255.255.255 x.x.x.x (indoor, outdoor) 10.195.0.1

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

Microsoft secondary authority w / Cisco router / PIX 501
I'm trying to get digital certificates to work on my 2621XM router. I have also
need to put in place on the three firewalls PIX 501 but who have not obtained until now still. I have
don't have no access to the CA root, but it could bring in line if I had to. I have
have a stand-alone Microsoft subordinate CA that I want to use to publish all
certificates.
Is it possible, as well with the router and the firewall? If so, what version
the IOS do I need? I installed the add-on CEP at HQ. I can't
It works and I'm starting to wonder if it is still possible. If this doesn't
work, how can I make it work? I have all the documents that Cisco has combed
on the subject and have gotten nowhere.
Any help would be greatly appreciated. Thank you.
Jennnette,
I sent this document, let me know how it goes or if you have any questions.

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.
