i am using a Cisco 1841 with subinterfaces instead (NAT on a stick).From the internet i can access services on public IP being hosted in LAN2. But when i try to access the same services on the same public IPs but sitting on LAN1, it does not work.

View 3 Replies View RelatedI am having some trouble understanding extended control lists. I am trying to prevent a certain host on LAN1 from accessing a server on LAN2, while still allowing the host access to the rest of LAN2.This is what I thought the command should be:
access-list 100 deny ip 175.16.1.2 0.0.0.0 175.17.2.2 0.0.0.0
My understanding was that:
Green = source & mask
Red = destination & mask
However this seems to stop all my other hosts on LAN1 from pinging the server also.
i use HG530, and i am connected to internet by lan1 out of 4,,, in last time my modem restart itself,,when modem work, first 2 lights (power and ADSL) are on and 3rd (internet) is flashing, when modem resets, first light is on second ligt is flashing and 3rd light is off,,, i tried to change cables and everything, but when i move cable from Lan1 to Lan2 or Lan3 i cant connect it says unidentified connection,,so how can i repair that,, and also technical support told me that my electric power is low and it cause modem to reset, is there any way to prevent that from happening if thats true?

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).
I am trying to figure out how this works. I have an ISP device that connects to my 1841. ISP and fa0/0 hold the /30 WAN addresses. Fa0/1 hold one of the public IPs, lets say 1.1.1.1/29. Then the outside interface of the ASA holds 1.1.1.2/29. Now I have two routes in the 1841, one for default route going back to the ISP device, and a route for the 1.1.1.0/29 network going to the ASA.Now I have 4 more publics I can use 1.1.1.3 - 6. I do not want to assign these IPs to the servers, but yet just NAT them. I know this is possible, but cant figureI took an internal host and did a one to one static NAT from private to public. Packet tracer says my NAT rules are ok. Allowed all IP traffic for testing and still can't ping the server.

I've tried this with both a source list NAT statement, and a route-map. The router can contact hosts on the Internet:
Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 128.31.0.51, timeout is 2 seconds:!!!!!Success rate is 100 percent (5/5), round-trip min/avg/max = 144/147/148 ms
Basically after upgrade from ASA 8.4 to 9.0 (2) I have problems when certain types of NAT.Example:SA 8.4: nat (LAN, outside) 85 10.252.253.123 source static 192.168.3.2 192.168.3.2 192.168.3.104 static destination service http http In this form the host 192.168.3.2 uses the mapped ip (192.168.3.104) to access by http while other ports can be accessed using the original IP (10.252.253.123).
ASA 9.0: nat (LAN, outside) 85 10.252.253.123 source static 192.168.3.2 192.168.3.2 192.168.3.104 static destination service http http In this form the host 192.168.3.2 uses the mapped ip (192.168.3.104) to access by http but unlike before now I cannot access to the original IP (10.252.253.123) using another port or ping from host 192.168.3.2.
I'm working on setting up a new ASA 5550, and have run into a question that I hope is easily answered.I currently have 4 interfaces, SL100 Inside, SL80 DMZ1, SL50 DMZ2, and SL0 Outside. I was under the impression that each interface, depending on security level would pass traffic from higher levels to lower, but not allow traffic being generated from SL80 to SL100.
What I would like to accomplish is that any hosts on my SL100 Inside interface can access the "internet" which is connected to my outside interface of the ASA, which was very simple, just a permit internal subnets eq www / https / etc...
My DMZ subnets need to access a few servers on my internal interface, and need outbound access to the world as well. Thinking that all traffic from my lower SL interfaces on the ASA would be denied, I entered a permit IP / DMZ subnet ------> any. This worked great for giving my DMZ hosts access to the internet, but it also permit traffic from the DMZ to hosts on my Inside interface as well.

View 3 Replies View RelatedI need to connect from an inside host to a host located in the DMZ zone for DNS queries. The host in the DMZ zone has a static NAT to the outside. The point now is that I would like to connect from inside to the NATed outside address, means to the public Internet address.
Inside host: 10.0.0.1 -> PAT for 10.0.0.0/8 to 20.0.0.254 (Outside Interface)
DMZ host: 192.168.1.1 -> NAT to outside to 20.0.0.1
The traffic should be 10.0.0.1 udp>1024 to 20.0.0.1 udp=53. The source IP address on the outside interface now is 20.0.0.254 (according to the PAT), the destination IP address 20.0.0.1. The DNS reply from 20.0.0.1 should go back now to 20.0.0.254 and then to the inside host 10.0.0.1.
I know that on the PIX it was not possible, to have outgoing traffic on the outside interface which immediately enters again the same interface. Can I realize this scenario with the ASA 8.4(3) release now?
I'm really bad on networking so I have a question about NAT. I got two public IP addresses from my ISP: 92.x.x.252 - 92.x.x.254. 92.x.x.254 is configured as secondary on external interface and clients will use it two connect (vpn) it from outside through cisco 1841 to zywall p1 with wan ip address 92.x.x.253. Is this configuration (look at picture) allowed? How can I route traffic from 92.x.x.254 to zywall p1, if posible?

We need to deploy a Cisco ASA 5510 behind the Internet facing router for Remote Access VPN (RAVPN). We bought the block of 16 IPs (in a different subnet) which is routed through the main router (69.x.x.x)and configured the outside interface of ASA with a public IP 64.x.x.x and subnet mask 255.255.255.240. Below is the network structure.
But, we can't access the ASA by it's public IP.

1) The users accessing the net via the nat are able to work without any inconvenience (good)
2) My servers which have public IP addresses are unable to reach the internet and subsequently I am unable to reach them via the internet (very bad)

We have ASA 5550, I have a portal server in the dmz which is natted statically to a public ip address for port 443. The application works fine from outside world. The server is also nated with a dynamic nat from inside to dmz and when I hit on the dmz ip from my inside it works fine.
The requirement for us is that the users sitting behind the inside (i.e. LAN) should access the server on the public ip address and not thru the dmz.

View 33 Replies View RelatedRecently I have changed my ISP and switched from an ADSL (4Mbps) connection to a faster fiber connection (100Mbps). I own an WAG120N which after firmware 1.00.12 (currently installed on the device is 1.00.16) should allow LAN1 to be used as WLAN. This is true and I can use it to connect to the new provider.
However the speed when using LAN1 as WLAN on WAG120N is very slow: download 20Mbps and upload 10Mbps. The LED on LAN1 is orange instead of green as before. I have tested the ISP connection with an WRT160NL and the speeds are much faster: download/upload 87Mbps

Both devices with their issue were working fine until the new firewall was installed. I’ve tried opening ports and adding ACLs but nothing seems to work. I’ve included my start up config.

I use the ios " c1841-ipbasek9-mz.124-15.T9.bin ", but it can't support ZFW. What kind of ios support ZFW. for example: ipbase, ent base, ip service ,advent etc.
