I have configured the ASA in a very similar manner to how the PIX was set up but I'm having trouble with some hosts on the inside accessing the Internet. Any inside hosts which use DHCP work fine. Any inside hosts with a static IP (and configured on the ASA with a "static" rule) cannot access the Internet. For example, in the config below the server daviker-dialler cannot access the Internet. I've spent a few days working on this now and have started from scratch several times but I'm not getting anywhere. Apologies for all the X's everywhere, didn't like to post anything sensitive on the Internet.
I'm working on setting up a template configuration for the Cisco ASA 5505 device that we'll use to configure more routers for various client needs. One of the requirements requested of me is the following: Internal hosts assigned a DHCP address are blocked from the internet Internal hosts with a static IP are permitted access to internet All internal hosts can communicate regardless of state
Now, I'm fairly new to this and I'm certain my terminology isn't correct so googling the problem has been fruitless. I have followed basic configuration guides and have configured the device to hand out DHCP addresses to hosts plugged in ports 1-7. If I'm plugged in and specify my address manually in the OS I am blocked from any access so I can only assume there is an access policy or some rule preventing me from authenticating against the router despite having set up VLAN1 to be the entire class C subnet. What sort of steps would I need to do to configure this? New access lists. For the record, the dhcp addresses are in the range of 10.100.31.64-10.100.31.95. VPN users are assigned an address from 10.100.31.220-10.100.31.240 and there seems to be no issues with that configuraiton. I don't wish to constrain what addresses a user can use should they specify a static IP (10.100.31.5 should be just as valid as 10.100.31.100).
I have, what I believe to be, a simple issue - I must be missing something. Site to Site VPN with Cisco ASA's. VPN is up, and remote hosts can ping the inside int of ASA (10.51.253.209). There is a PC (10.51.253.210) plugged into e0/1.
I know the PC is configured correctly with Windows firewall tuned off. The PC cannot get to the ouside world, and the ASA cannot ping 10.51.253.210.
I have seen this before, and I deleted VLAN 1, recreated it, and I could ping the local host without issue. Basically, the VPN is up and running but PC 10.51.253.210 cannot get out
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.
At the end of the day I simply need to upgrade the license on my ASA 5505 v7.2.4 (upgrade will come later as part of a larger project) to allow for >10 Inside Hosts. From what I've read there seems to be a 50 license upgrade out there. Can this be purchased directly? From whom? Will it only affect the Inside Hosts number and not affect any other licenses, configurations, etc. Just being overly cautious since this is way outside of my normal realm. Below is the current activation-key information....
Result of the command: "show activation-key"
Serial Number: xxxxxxxxxxxxxx Running Activation Key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
I am having difficulty following the logic of the port-translation. Here is the configuration on a 5505 with 8.3,So I would have thought the outside access-list should reference the 'mapped' port but even with 3398 open I cannot remote desktop to the host. If I open 3389 then I can connect successfully.
I am using a three interface ASA config (Internet, DMZ, Inside). The DMZ and Inside networks are both RFC 1918 space however it is against our corporate policy to allow our DMZ IP space to be internally routable, therefore we must target routable IP's which NAT to the DMZ hosts . In my DMZ network there are two devices - a Web Server and a 802.11 Access Point.
The Web Server is hosting our corporate web site. When the clients accessing the internet via the Access Point try to access our corporate web site they are not able to. A DNS lookup of the A record 'www' returns the public IP address, which when targeted translates to the real RFC 1918 IP of the web server.
Is there a way to use destination NAT or another clever config so when a host targets a public IP which is being translated on a different interface right back into the same interface it originated from it would allow the traffic?
How can I get DMZ hosts to be able to access the Internet via the Outside interface of my ASA5505.I am using the DMZ to allow temp guest acces to the Internet.
Here is my configuration and it can be changed as needed.

I am using ASA 5505 firewall with base-license. I connected my firewall to one cisco 3750 switch where i created 5 vlans. I done NATing for all vlans and they able to get internet and working fine. They able to browse all internet sites like gmail and yahoo mail.
All internal users are configured to use Outlook for their webmail. Here the problem is with outlook they are unable to send and receive the mails.
If they directly connected their system using public ip( Directly from ISP) they able to send and receive mails from outlook.
I just replaced a PIX 501 with a new ASA5505. I had a very weird problem and would like to know what caused it incase I run into it again. The setup is a DSL connection, with an old-ish speedstream DSL modem. Static IP, no PPPoE. I had a PIX 501, then two servers with static NAT entries on secondary WAN IPs. Everything was working fine on the PIX, I just duplicated the config over to the ASA. I swapped out the PIX for the ASA, and rebooted the DSL modem to clear out it's cache. After installation, NAT was working fine for the the global pool, but the systems with static NAT could not get online. I tried lots of different things to fix them, and they never worked. Finally I rememberd running into an issue like this a long time ago, in that the static NAT IP's wouldn't work without giving them a bump-start on the network. So I assigned the ASA each of my WAN IPs, one at a time, and tested them all. After that I went back to the original WAN IP, configured the static NATs, and they fired right up. why did my static NAT entries not work until I first assigned them to the ASA, then swapped back? I did reset the DSL modem when I swapped the firewalls, so I don't believe it was an ARP issue (unless it was an ARP issue at the far end?) I would like to know if there is something I can do differently with the devices or with the config to not have this issue again in the future.
Currently a customer has all theLAN devices using a router as the Default Gateway. The router also do the Dynamic NAT to the internet access and has NAT/PAT rules to publish some services like HTTP and FTP. As I know the router will permit all the incoming traffic in all its interfaces without restrictions at less there is an ACLs that restrict the incoming traffic on an specific interface.Now the customer has bought a brand new ASA and wants to use it as the default gateway for the entiery LAN. This means, the ASA will have the internet connection and will be the responsible for the NAT/PAT process.
I have configured the NAT/PAT rules already following the current router configuration, but I need to know if I have to configure ACLs allowing the incoming traffic on th Outside interface for the services I NATed.
I have a Cisco ASA5505 running 8.2(1) and I am using ASDM to manage the firewall. I have a Linux VPN server on the inside with and IP address of YYY.YYY.YYY.39 with a static NAT to the outside with an address of XXX.XXX.XXX.171 . I have a site to site VPN tunnel which terminates on the outside of the ASA on the outside interface XXX.XXX.XXX.190 .Traffic from the YYY.YYY.YYY.0/24 network can't transverse the site to site VPN as there is a conflict of IP address's on the far side so it is natted via a dynamic policy to host address ZZZ.ZZZ.ZZZ.100, Users remote into the inside(YYY.YYY.YYY.0/24) for support via the Linux VPN server (.39) and then need to communicate down the site to site VPN. The problem is that the static NAT for the incomming connections takes preference and bypasses the site to site VPN tunnel for outbound traffic. I tried to create a policy Static nat but it tries to modify the static nat that handels the incomming traffic to the Linux server.
i have 2 internal server sitting in inside interface
inside network vlan 1 ip address 192.168.0.20, and 192.168.0.22
i going to map 192.168.0.20 to public ip routable address 203.117.124.180 and 192.168.0.22 to public ip routable address 203.117.124.181
the purpose is to make those 2 server 192.168.0.20, and .22 to be able to access remotely using public routable ip address,
however, after done the configuration i still not able to ping or access the public IP Address mention above. my both server are turn on and can access internally.both server are also able to access internet. See below partial configuration retrieve from Show Run.
I have a 5505 for a small business that has one web server. The web server has a static NAT entry to an IP address and not an interface. There is an access rule allowing any HTTP traffic to the outside IP of the web server. From the web server I can't access the Internet.
All other computers on the network can access the Internet using a dynamic nat rule that uses the outside interface. The web server is accessible from a computer behind the firewall.
If I delete the static NAT entry for the web server I can get on the Internet.
I have turned debugging on and see that an outbound connection is built and then 30 seconds later the connection is torn down with the bytes 0 SYN Timeout message.
I have an ASA 5505 behind my internet router. i have got only one public ip configured on the router outside interface.192.168.20.0/24 subnet is configured between ASA and router and inside network is 192.168.10.0/24 (Refer the attached diagram).
I have exposed my mail server and ftp server to public through static PAT in router and ASA with the same public on router outside interface. Iam facing issue some of the machines inside my network internet is not working(actually DNS is not resolving) some of the PC's internet is working fine some of the PC's randomly working. i have attached the diagram and ASA config , after this issue is sorted out i need to configure a L2L VPN to my head office.
I am mapping static ip address to the local ip address.We have a bsnl broadband connection, and bsnl has provided us with one static ip address.We are using broadband modem.Now I would liket to map this static ip address to one of the private ip address which is 192.168.1.2(database server).i want to do nat above ips if i do so then i dont have no ip to assign to my outside interface.I would like to access this device over internet, by typing my public (Static ip ) given by the BSNL.security device i have is cisco ASA 5505.
I am setting up a Cisco ASA 5505 first time for My organisation, I usually setup Cisco Router, I have 10 Static IP, & Have 6 Server (S-1, S-2, S-3, S-4, S-5, S-6), Traffic Should be pass through the ASA and is distributed to the destination server that is specified in the packet. LAN servers can be separated into discrete networks for security. For example, a private LAN for internal traffic accessed only via remote dial-in VPN sessions and Want to Configure DMZ for Server (S-4, S-5, S-6) that allows public web traffic.
I have Attached My Network Diagram I have some question,
1:- Can we Configure Multiple Static IP On ASA 5505 ?
2:- If Diagram is wrong what change need to be done ?
I have ASA 5505 with basic licence, v9.1, ASDM 7.1. I want to create the DMZ for a web server.
The interface 0 is for the outside network The interface 6 is for the DMZ All other interfaces are for the inside network
My ISP provided me with one public static IP address, one gateway address and a subnet mask 255.255.255.252
1/ I would like to ask which interface I should assign the public static IP address to. Should it be assigned to the outside interface 0, or should it be assigned to the DMZ interface 6, while outside interface would be configured to use DHCP?
I tried to assign the static IP address to the outside interface first, but then when I used ASDM the “Public Servers” feature to configure NAT, I get error message that the outside interface and the public address cannot have the same IP address.
2/ For the sake of peace of mind, I am thinking about using the second firewall, which would be used only for the inside network. Can I connect this second firewall to one of the inside interfaces of the 1st firewall,
I have created a simple static ip address by using this command:
interface Vlan1 nameif inside security-level 100
[Code].....
But, no matter what, the I can't ping the static address or access the computer 10.2.1.2 from outside of the asa 5505. I have attempted to ping from inside of the asa 5505 or from another computer. I just does not work.
I also have created several rules that allows icmp traffic.
icmp unreachable rate-limit 1 burst-size 1 icmp permit any echo-reply inside icmp permit 10.2.1.0 255.255.255.0 inside icmp permit any echo-reply outside icmp permit any outside
I just upgraded my firewall to ASA 5505. Now, my original static ip address cofiguration is gone. Apperantly, Cisco went away from static ip address to something like nat (inside,outside) dynamic interface. how to create a static ip address under version 8.4? By the way, I am sharing what my configuration used to look before upgrading.
I was checking out the config on my ASA and noticed a bunch of static routes configured when I did a show route. With the exception of two that I expect to be there, the remainder point traffic destined for specific internal hosts to the outside interface, i.e.
S private_ip 255.255.255.255 [1/0] via public_ip, outside
I verified that I cannot ping those hosts from the firewall. I logged in to the ASDM. When I check the Configuration>Device Setup>Routing>Static Routes it only shows two static routes, the ones I expect to see. If I look under Monitoring>Routing>Routes, I see the same output as I did on the CLI. I looked around to see if I was missing a key location for this information, and I was able to see the same static routes output in Monitoring>Routing>Routes. Since this is under monitoring though there's no way to delete these routes, and I still don't know where they were configured originally. Then I happened to check under Monitoring>VPN>VPN Statistics>Sessions, and I see several of the private IPs used in the static routes being used by VPN users, including my own! I know I didn't assign myself a static IP for VPN use or anything like that. So, what are these static IP routes? Why do I see them in the CLI and not under the Configuration tab? I mean, I know I can delete them from the CLI but I'm trying to figure out why the info is not synced. Am I seeing dynamically created content based on the VPN connections?
Now I would like to start using the clientless VPN feature of the ASA, so I of course don't want that particular port forwarded to the server. Is there a way to define such an exclusion? I've tried several things, including setting up a separate NAT rule to direct that port back to the ASA's interface, without luck.
If that is not possible, what configuration would I need to move to in order to get the behavior that I want? It is important that all (non-VPN) traffic is passed exactly as it arrives at the firewall (whether it is coming from internal or external), with the exception of changing the IP address (i.e., I need static port mappings for some of my services).
configuring ASA 5505 to be able to ping remote host.Setup - We have a site-to-site (192.168.1.0/24 - 192.168.2.0/24) VPN setup with client VPN access (IP Pool, 172.16.50.0/24) on 192.168.1.0 ASA 5505.Issue - Not able to ping host on 192.168.2.0 from VPN client 172.16.50.0 but able to ping 192.168.1.0 host.
I have configured Static NAT on ASA 8.4; and opened the telnet access through following configuration but it is not working. What mistake I am making in my configuration
I am having a problem getting this to work and I have always done it with 2 Static ip address. but now this company changed to 1 and I am doing something wrong.
I have comcast with 1 static IP, I have a local LAN with 6 host and 1 server that does Mail and remote access and web traffic.
I need a config that allows me to use 1 static ip on the outside interface of the PIX and allow with an ACL 7 ports open to the server and allow all the local host out to the internet.
I've got an ASA 5510 that has been working like a charm for some time now. Until now we've not had to nat any resources to the outside. I created network objects for an internal host and an external host. The internal host has to respond to requests on tcp/2001.
The internal host has no problem accessing the internet, but when I attempt to access the internal host from the outside, I get the following:
The old syntax that I am much more familiar with has been deprecated. On older IOS it would have been something like static (inside,outside) tcp 209.114.146.122 14033 192.168.30.69 1433 netmask 255.255.255.255 Plus an extended ACL to allow the traffic.I am trying to create a Static PAT to allow a host address to access our Network through an ASA. I have external address 209.114.146.122 that I want to hit the external interface on an obscure port (say 14033) and translate that traffic to an internal host address on port 1433.
I am trying to block access to facebook and twitter on my router, to a certain range of ips, 192.168.1.8 - 254. I have been digging around and trying stuff but all I do seems to restrict everyone access to the internet.
I have a site to site vpn connection between ASA 5510 and PIX 515 which is working fine. There is no problem for hosts on any side of the tunnel to access a cross. However the local ip (192.168.20.1) on the client interface of my PIX is not allowed to access hosts on the other side of the tunnel. [code]
