I have just received 4 static ip's from my isp, i want to be able to point these ip's at different services on my internal servers, for example: [code]. The firewall I have is Cisco PIX 515, how to set the NATing up or commands?
View 1 RepliesI am currently trying to apply a reverse NAT on asa 8.2 and not sure how to do this. I have done this on asdm 6.2 for asa 8.3 but the options are not simiar on 8.2. Is there a CLI equivelant?
I am trying to Achieve the object below for any traffic coming from outside interface to the inside interface with any source address to destination 10.X.X.58 then translate it so that it become 192.X.X.X to address 192.X.X.58. This is so that communications can traverse internal network as the server is not ona DMZ.
I have done this on 8.3 (shown below) but do not know if it is possible for 8.2, I have tried replicating the same command on 8.2 but commands are not recognised.
nat (outside,any) source static any 192.X.X.X destination static 10.X.X.X 192.X.X.58
Should I just upgrade to 8.3? never done it before so not sure of the consequences.
Problem with the PIX 525e while "NATING ".
View 3 Replies View RelatedI have Pix firewall 515e on inside interface its has configured with IP 192.168.0.254.And Global Nating is configured.
global (outside) 1 interface
nat (inside) 1 192.168.0.0 255.255.255.0 0 0
I want i configured Global nating only for only specific IP address E.g 192.168.0.0-192.168.0.30 and 192.168.0.200-192.168.0.254?How i do this?

Interfaces:
OUTSIDE - 194.50.90.221 255.255.255.0 / security level 0
DMZ - 192.168.12.254 255.255.255.0 / security level 25
INSIDE - 192.168.0.6 255.255.255.0 / security level 50
Now, if I want to ping from the DMZ to INSIDE, I get an error message "no translation group found for icmp src DMZ: ...... dst: INSIDE...."
I fixed is by adding "NAT 0" onto the INSIDE interface so that packets originating from "INSIDE" that are destined for "DMZ" do not get NAT'd.
Now my question is, becasue these are all directly connected networks, how come the firewall does not route the packets, but tries to NAT them instead.
I have a DVR installed inside my network with local ip address 10.0.0.117/24 and i need to access it from the internet. there is a pix 515e (ios ver. 6.2) between the internet and my internal network. I've configured NAT from inside to outside to allow my internal clients to access the internet. but i need to allow external clients from the internet to access the DVR. I've tried to configure it on my pix but i found it doesn't have more options for nating like ASA.
is there any way to do that on pix and if so what the correct commands to do that.
I have a Cisco ASA 5520 (Ver 8.2(4)) with all four interfaces in use (Public, Private, DMZ, Local offices) and an IPS module, so there are no spare interfaces. I have used all of Public IP's on the current interface for various services (these need one to one mapping, so I can't port map mainly due to SSL certificate issues) and I need to add another Public IP range. The secondary option on ASA interfaces does not exist as on routers/switches and I need to use an additional non contiguous IP address range for additional services advertised on the Public interface that are NAT'd to be servers in my DMZ.
I have seen an example of adding a static arp on the Private interface to allow a secondary gateway to be used for outbound traffic, but I need to allow 14 new IP addresses to be NAT'd from the Public to DMZ and possibly also for outbound NAT'ing (from either Private or DMZ to the Public). I have a L2 switch between the ISP router and the firewall, so using VLAN's is not an option unless the ISP can be persuaded (highly unlikey) to add the seondary IP's as a sub interface with tagging. Anyway if this was actioned then we would have a massive outage on our current IP range during the transistion.
I have an ASA5510 running version 8.2(5) I am having an issue with routing/natting from an internal network to the outside interface IP on port 443 which has a nat back in to another internal address. i works externally in from a public address. i also see log messages to do with IP Spoofing
View 1 Replies View RelatedWe have an ASA with 8.4(5) version. we had detected that few ip's were getting shunned ,to overcome the problem no shun was used and the traffic normalised.But, the same problem re-occured a few days after that with logs showing traffic being shunned.
is there any fixed way to get rid of this. what commands can i use to verify related configuration on the firewall.
I try to get a ASA with the new software 8.4.2 running. On an old pix we had the nat command: static (inside,outside) tcp interface www 192.168.15.252 www netmask 255.255.255.255 0 0,In all the new documents about 8.4.2 I can find that it should work with something like:
object network web_host nat (inside,outside) static interface service tcp www www
I want to forward http traffic from the outside interface to this host. In the log I just get entries about blocking ACL - but both is allowed on the outside access-list - traffic to the inside IP and also to the outside interface IP.
I also tried it with "Public Server" - but when I try to use the Interface address I just get the message: Address x.x.x.x overlaps with outside interface address.
Is it still possible to do port forwarding on the outside interface?
I am trying to set up a SLA statement on an ASA 5505 version 8.2(5). When I enter the command "sla monitor schedule 1 life forever start-time now" I get a message stating "%Entry not configured."

View 3 Replies View RelatedCurrently have an ASA 5545. What I want to do is allow our support team to perform ALL show commands (up to and including show run) but not enable them to perform ANY configuration changes on the devices (not get into config t). This is to allow them to check ARP tables, routing protocol status, etc
i don't have access to the ASA at the moment and haven't been able to figure it out in IOS, i'm assuming its not too hard.
I want to know with an ASA 5505 w/ Security Plus License I get up to 20 VLANS/Named Interfaces.I have a customer that is getting a new subnet of external IP addresses from their service provider and a different default gateway to accomodate re-hosting their datacenter at their main office instead of at a Colo. My question, when building out their new DMZ, can I have multiple route 0.0.0.0 commands?
Example.
Current Default Gateway 1.1.1.X
Internal hosts 192.168.1.0 use and are natted to 1.1.1.X
New Default Gateway for DMZ Servers 2.2.2.x
Internal hosts still use 1.1.1.X, but server hosts in 192.168.1.3 should use 2.2.2.X -- there are also a bunch of pre-existing static NAT rules for these servers such as 2.2.2.30 translates to 192.168.1.30.
I think I would accomplish this by using the following:
route inside 0.0.0.0 0.0.0.0 1.1.1.X
route DMZ 0.0.0.0 0.0.0.0 2.2.2.x
Would this be correct?
How to view the commands that someone changed the configurations in ASA 5520?

I just get "unrecognized command" on a router that is supposed to support such features. I'm wondering if it has something to do with the IOS image.

View 6 Replies View RelatedI have a client with an ASA 5505 who has several networks he's trying to get communicating over a VPN tunnel with a remote office. One of the networks is not working because it's also in use on the management interface of the other side of the tunnel and neither side seems willing to re-IP their internal space.
Their proposed solution is to NAT the conflicting network on the firewall on this side to a different subnet before passing it across the tunnel. How do I implement a NAT that only the VPN tunnel uses while keeping the rest of the traffic that comes across this device un-NATted?The network in question is 192.168.0.0/24. Their desired NAT target is 172.16.0.0/24. ASA config is attached.
Our ISP gave us a /30 for our external connection (with one IP being their side, and the other our firewall's outside int) and they then route a /28 down to us to give us 14 public IP addresses. Usually we use static NATs to give internal servers a public IP, and it works fine.
However, now I need to setup another VPN device with a public IP from our /28 pool. How the heck do I nat that? Should I give it's external int a private IP, and then NAT it at the first firewall? The 2nd firewall will be a VPN end point, and I'm afraid the NAT will break that.
I just migrated our office network router to a RV082. While configuring it, I came across three problems:
(1) From our ISP we have four public IP addresses which I want to make use of for outbound traffic. With the previous router we used we could configure LAN IPs(ranges) to map to static public IPs. Does RV082 support this? I could not find an option for that at the web-interface. From what I understand the 1-1 NATing only goes both incoming and outgoign ways and actually is 1-1 and not the many-to-one I am looking for.
(2) How is it possible to configure incoming port forwards to use a specific WAN interface? Will it always be the primary WAN interface?
(3) Does the telnet access provide more configuration options? I could not log in to it with the same user credentials as with the web-interface.

View 2 Replies View RelatedWe have a RA Vpn split_tunnel setup in one of our locations which is working fine in all areas except for traffic destinged for one specific website using https. This vendor only allows the HTTPS connections to them to come from certain outside IP addresses. ssentially it should work like this:RAVPN_client (10.4.4.0/27) --> https request to vendor_ip (208.x.x.x) ---> ASA55XX --> NAT_to_outside_ip --> https request to vendor_ip (208.x.x.x) need to understand how you would go about NATing ONLY this specific https traffic from the RA VPN while not having to alter the setup otherwise. Internal hosts (aka behind the ASA physically) do not have any issue getting to this site, as its nat'd to the outside ip address as we expect.Here is what we are using for the NAT Exemption list he 10.2.2.x, 192.168.100.x and 172.23.2.x are other remote sites that we have. RA VPN users are using the 10.4.4.0/27 do not have any issues connecting to them, no matter the protocol.
View 3 Replies View RelatedI have the following network connected and configured to a single Cisco 1800 router.
VLAN 2 (10.1.20.0/24)
|
int vlan2, ip address 10.1.20.1
|
Cisco 1800 ----- int fa0, public ip address ---- Internet
|
int vlan3, ip address 10.1.30.1
|
VLAN 3 (10.1.30.0/24)
VLAN 2 is server vlan with a webserver.
VLAN 3 is clients.
NAT configuration:
VLAN 2 and VLAN 3 is using NAT to access the internet, and both is configured as inside interfaces.fa0 is configured as outside interface. Now I don't know if this is about NAT, but I've tried several things without luck.
Problem:
A client in VLAN 3 tries to access a domain on the webserver in VLAN 2.It starts by sending a DNS query to a DNS server located at the ISP, and gets the ip address for the domain, which is of course a public ip address. Then nothing happens because the client tries to access the domain on the webserver using the public ip address, and the webserver have a local ip address 10.1.20.20 which is on the local LAN (VLAN 2).
I've tried NAT because I have to change the destination ip address, but I can't seem to get it right.

We have to ISP's, and I would like to allow traffic to come in on either interface to our internal LAN to a few servers.

I have a doubt on how do nat 2 internal ip addresses to 1 public ip for FTP uses.
As I know Cisco ASA cannot use to nat 2 internal ips to 1 public ip as the ASA cannot read the host header. It there anyway to control it by using acl or network object group?
My current configuration for nat 1 internal ip to 1 public ip:
static (firewall-dmz,firewall-outside) tcp 210.19.xx.xx 21 172.16.101.11 21 netmask 255.255.255.255 dns
I have Router 2800 series Global nating is configured on it.

My object is that i want give internet access only for few users ip E.g IPs addresses from range 192.168.1.0-10 can acess intenet access other all are deny.How i do this with ACL .
