I have ASA 5520 with Version 8.2(5), the ISP give me a block of IP pubic (201.148.156.193/28), one IP valid (201.148.156.194) have the Global NAT (all users LAN) and server FTP, but i need that IP 201.148.156.195 is used for VCSe, and the IP 201.148.156.196 is used for other server FTP.
View 5 RepliesI have ASA 5520 with Ver 8.2.Outside interface is directly connected to ISP's router(TelePacific) and is assigned one of public IP:198.24.210.226.There are two servers inside the network with the private IP's:192.168.1.20 for DB Server, and 192.168.1.91 for Web Server.I did Static NAT 198.24.210.226 to 192.168.1.20 and 198.24.210.227 to 192.168.1.91.When I access DB Server(198.24.210.226) it's working OK but when I access Web Server(198.24.210.227) there is no response at all.I checked the inside traffic, it even did not get into the firewall.Is this the problem with ISP's router? How can we route all of our public IP's to the outside interface(198.24.210.226)?

i need to allow https traffic to a server in the DMZ that will have a routable IP address will just an ACL suffice ?which interface do i apply it to ? wan or dmz ?i dont need a NAT since the DMZ is a routable space?
I have three public IP:s from /24 network like 83.x.x.10, 83.x.x.25 and 83.x.x.41 all using netmask 255.255.255.0.
I'm using 83.x.x.10 on ASA outside interface and trying to do static nat for inside servers with those other IP:s, but not yet solved it.
Using Cisco ASA 5505 software v9.02
Config:
object network obj_guest
nat (guest,outside) dynamic interface
object network obj_any
nat (inside,outside) dynamic interface
object network w2008
host 192.168.1.10

This works other networks that are like whole network with /29 mask and have router in front of ASA using bridge. But in my case i just have DSL modem bridged in front of ASA. This static nat works like should if i use like Zywall USG series fw and this same configuration works in my customers, but they have those scenarios i said having mask /29 and router in front...
It seems that the problem is in ASA, like i won't show those public IP:s to public router from my operator. Because if i roll those other public IP:s on my ASA:s outside interface: i will use 83.x.x.25 and 83.x.x.41 on outside interface and after that put back my original 83.x.x.10 then my static nat is working just fine, atleast few hours, but not in next morning because ISP router flushes ARP cache.
Attached is my updated ASA 5505 (8.4[2]) config. With this config, basically the "laptop" group works fine, but the leo and orion groups don't ever receive packets inbound. No DNS, nothing.
The laptop is windows, the other two are servers with two NICs. The interface cards are Intel Pro/1000s. I've been through everything including Vlan protocol conflicts and actually enabled the servers for 802.1(Q).
Is it possible to two or more public IP Addresses bound to a Cisco ASA 5505 running 8.4(2).
View 9 Replies View RelatedI'm currently replacing my ASA 5505 with a 5510. I have a range of public IP addresses, one has been assigned to the outside interface by the setup wizard (e.g. 123.123.123.124 ) and another I would like to NAT to an internal server (e.g 192.168.0.3 > 123.123.123.125). On my asa 5505 this seemed fairly straigh forward, i.e. create an incoming access rule that allowed SMTP to 123.123.123.125 and then create a static nat to translate 192.168.0.3 to 123.123.123.125. Since I've tried to do the same on the 5510 traffic is not passing through so I'm assuming that the use of additional public IP addresses is not handled in the same way as the 5505? I also see that by default on the 5505, 2 VLANs are created, one for the inside and one for the outside, where as this is not the case on the 5510. Is the problem that VLANs or sub-interfaces need to be created first? I'm doing the config via ASDM.
Everything else seems to OK i.e. access to ASDM via 123.123.123.124, outbound PAT and the site-to-site VPN.
How to setup this Nat on an ASA 5520 running 8.3.2 code? I know this must be possible as I can do the same thing on my Check Point with no issues. I need to Nat two dmz mail servers to one public mx record. I will have an F5 to load balance inbound and outbound traffic from the mail servers. So I need to Nat two private IP’s to one public.

View 1 Replies View RelatedAny confirmation that the versions 8.6 and up don't allow publishing to more then one public range if IP addresses?
We have ASA5520 version 8.4 in deployment and there I can NAT to 3 different ranges of public IP-s.
With same configuration on ASA5525-X version 8.6 it will NAT only the range that the outside interface belongs to. Also tried the 9.0 version with the same result.
I'm stuck at asa 5505 nat, port forwarding configuration Here is what i need:
host1: 192.168.1.1 service tcp/100 >>>>> public ip 1.1.1.1 service tcp/100
host2: 192.168.1.2 service tcp/200 >>>>> public ip 1.1.1.1 service tcp/200
host3: 192.168.1.3 service tcp/300 >>>>> public ip 1.1.1.1 service tcp/300
So people from remote just need to use 1.1.1.1 public ip to access all the ports on three different inside server.I can do this on my old ASA 5505 with 8.0(4). Looks like there're lots of change from 8.0 to 8.4.
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.
How can we host 300+ secure (https) websites using a couple of public IP's on an ASA5520 with AIP SSM-20 and with as few certificates as possible?
Summary of set-up:
We currently host a number of websites using an ASA5520 and use host headers, so have 6 servers with around 40 hosted URL's. The number of websites is due to double very soon and we will need to use more of our public IP's. We can see that we will will run out of public IP's very soon especially as there is a project in the pipeline that has a likely requirement to host an additional 200+ websites.
Each of these websites are required to use https and therefore each must have a certificate which will be very expensive. PCI DSS (payment card industry data security standard) is causing us issues because we had hoped to post the certificates on the firewall (one for each physical server) and then run the data UN-encrypted from the firewall to the relevant web servers, so that we could use one certificate for lots of websites and therefore reduce our certificate costs, however is not best practice to do this due to the data being unencrypted within the firewall and on the DMZ network and therefore potentially open to compromise. I doubt that we could install 200+ certificates on a 5520 and then re-encrypt the data to the web servers especially seeing as we also have an IPS card that is already running at around 70-80% util due to the performance overhead.
BTW - We also have an in-line Breach WAF which will be required to inspect the packets (certificates to be installed on the WAF to allow this).
Currently in our environment we have have two buildings with an ASA 5520 in each and a core stack of 3750's in each building. I am currently working on a network segmentation project and am thinking of adding another stack of 3750's in each building to add more redundancy to our network. This will allow our access layer switches to have a trunk to each stack and prevent an outage if one of the links or stacks were to go down.
My question is how I would set this up on the ASA end of things while using a common subnet and HSRP on the 3750's. I understand how to use HSRP and STP on the switches to achieve this on the 3750 end of things. I saw you can do etherchannel on the ASA with 8.4 but how does that work in a failover situation?
I've got a cisco asa 5520 and setting up the NAT for multiple DMZs on it.
I want to use PAT on the outside interface.
internally ive created subinterfaces for the VLANs and connected to a trunk port on a switch.

Got an ASA5520 running V8.2(3) and we want to upgrade our internet bandwidth. Our ISP says OK but we need to install different physical circuit, upgrade CPE router, etc.
Then they say, btw your globally allocated IPs will change - this is a problem as we have Site-to-Site VPN Tunnels, IPSEC RA, etc.
ISP are proposing to give us a 3 month period whereby old & new IP blocks will be routed to our ASA (by means of secondary IP address on their Cisco CPE).
Multiple IPs on the same physical i/f on the ASA require sub-interfaces/IP Addresses/VLAN ids on my "outside" i/f.
Is this going to horiibly break Site-to-Site VPN Tunnesl, IPSEC remote access ?
Will VLANs work at all with IPSEC on the "oustide" i/f at all ?
I need to configure multiple context mode with active/standby failover solution.
Even after reading some Cisco documents I still can't understand if active/standby failover configuration has to be done within the admin context only or also within every single context (context-1, context-2 for example). In this case I have to allocate as failover interface a subinterface for each context (admin, context-1, context-2), right ?
Therefore a I have an other question: within the admin context, in a failover solution, do I have to allocate all interfaces I want to be moniotred, even though some will be used by context-1 only context and some others will be used by context-2 only context ?
An other question is: if active/standby failover configuration has to be done within each context, can I set regular failover within context-1 while stateful failover within context-2 ?
The last question is: can I use management interface within all 3 contexts ?
I've currently got my ASA (5505) serving a /28 public subnet. I've ran out of IPs, so my DC has issued me an additional /24 subnet that they have routed to my ASA. What needs to be done on my ASA so be able to use these new addresses? I've been trying to search and not been able to find a good answer (some say I shouldn't have to do anything, everything else references NATing, which I currently don't do and would rather not do).The servers I assign these to, I'd like them to have the public ip assigned directly to them.

It's connecting to a UK ADSL2+ link.I'm a penetration tester and I want to put the Cisco router in front of my existing firewall which has an IPS on it, so that it doesn't get in the way of port scans and vulnerability scans. My ISP has issued me with 14 usable addresses a/240 subnet and basically I want to be able to use the route with just the public IP addresses. I have configured Cisco routers before, but never with this type of configuration. It's always been single public IP address NAT'd through to one or two internal LAN's.
It will be nice if I could assign the wireless and fast ethernet ports to the same VLAN using the public addresses. I don't want to use DHCP I'm quite happy statically assigning IP addresses to the computers wireless and LAN interfaces. I am reasonably certain this is possible because not sure how to do it and a little busy at the moment carrying out penetration tests.
I am configuring this new router for a client. I am running into an issue that I cannot get working. They use 5 public IP addresses. Currently the wan port on the router is .66 and I have all the ports forwarded to the correct internal IPs. This works fine. However I need to forward parts from other public IPs (ex: .67) to internal IPs. So far I have been able to accomplish this via the One to One NAT feature. It allows me to forward ONE port from a public IP to a private IP. However I need to forward 3 or 4 ports per public IP to a single internal address. Does this router not support that functionality?
View 2 Replies View Relatedwe need to implement a scalable solution where we can provide for each customer it's own public IP so that they can access some content restricted by IP range.the solution consists of a proxy software that will "listen" to multiple IP's, then reroute the HTTP requests and rewrite the URL's to a different format.Anyways, we came to the conclusion that what we need is the following:
- broadband line with a pool of 8 IP's
- a router that can support multiple IP's
- a server
what kind of router or device is required for this kind of configuration. basically the network diagram will be like this:

we should be able to add the same above combination once we run out of IP's, another broadband line, another device and server ...
If there are any small business routers that offer one-to-one NAT? I have several public IP addresses assigned to me by CenturyLink. I have two servers that provide email and web hosting for two different domains. I want to put the client machines on one VLAN (VLAN Z) and assign it a public IP address (to keep server traffic separate). I want to put each server on its own VLAN (VLANs X & Y) and assign each server its own public IP address. I need the router to be able to provide a firewall and port forwarding for each VLAN. I also need to be able to route traffic between VLANs so the clients on VLAN Z can access their email and the websites on VLANs X and Y. I also need to be able to route DNS traffic between VLANs so each server can provide name resolution for their respective domains.
So, is this possible with a small business router or do I need to look at something different? I'm fairly certain this configuration is not possible with my current Cisco RVS4000. What it boils down to is I need a router that is capable of having multiple public IP addresses on the same interface and to forward those public addresses to private VLAN subnets. This would be one-to-one NAT if I understand it correctly..
The client has a Cisco RVS4000. There are 3 Internet devices need to be accessed from the outside and will use one public IP for one device. I don't see any options to setup on Cisco RVS4000 to do 3 NATs. If Cisco RVS4000 doesn't work in this situation, which router will do?
View 1 Replies View RelatedAt my company, we lease 3 static public IP addresses from 1 ISP. We want to have 3 separate networks that each use one of the IP addresses. Network 1 is the computer network, network 2 is the VOIP network, and network 3 is the security camera network. I am trying to determine the best way to do this. I have come up with 2 solutions in my head, but I'm not sure if they will work or not. I would like to get some input. Solution 1:Solution 1 looks something like this. Fiber box -> Router-> 3 switches. There would be one WAN input on the router, that would have a static route to 3 different LAN ports. For example, address 24.244.208.101 would be assigned to LAN port 1, 24.244.208.102 would be assigned to LAN port 2, and 24.244.208.103 would be assigned to LAN port 3 (by assigned, I mean have a static route to it). Is there some type of router that is capable of doing this? Solution 2:Solution 2 looks something like this. Fiber box -> Switch -> 3 Routers. The ethernet cable would run from the Fiber Box to a switch, and then 3 routers would be plugged into the switch. Each router would have the Static information configured in them. Would both of these methods work? If so, which would be the best way to go?

View 2 Replies View RelatedWe have a Cisco ASA 5520, and we're creating an IPSec VPN to another Cisco ASA. We have multiple VPNs on this firewall.
The issue with the latest one is they require a Public IP as the Local Encryption Network. I've seen this question a couple times while searching but never really a definitive answer.
Would using the "Outside-Network" as the local encryption network, then natting the appropriate IPs be sufficient? Or would this not work at all?
Our Public block is X1.X1.X1.64 - X1.X1.X1.79, our Peer IP X1.X1.X1.66. Would using X1.X1.X1.64/28 as the local encryption network make the connection? Then NAT the needed IPs from our DMZ X2.X2.X2.71 as X1.X1.X1.71 to the client?
Would this work or am I way off the mark (I'm by no means an ASA expert, and an ASDM explanation would work over command line).
Edit: Or would I have to create a new Global Pool made up of Public IPs on a different subnet mask than our actual Public IP address pool. And make that our Local Encrypted Network? I think this might be it, but could it cause IP overlapping? Our webserver is part of this and I'm worried about causing connection issues.
