Cisco Firewall :: Unable To Reserve Port 443 For Static PAT In Asa 5510
Jul 15, 2011
This problem applies (in my case) to our ASA5510. The issue here is that the http service on the ASA is runnnig off of the standard port 80. Login to the firewall and run the following.no http server enable http server enable 8080,Now you should be able to add a NAT/PAT on port 443 to another server of your liking. Just remember when you attempt to use ASDM to manage the ASA in the future to specify the new port 8080.
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 have a Cisco 5505 with a 12Mbps feed. I want to reserve 2Mbps for RTP traffic. I followed the QoS guide here: url... The goal would be that any traffic destined for port 5000 through 5100 UDP or TCP from any IP to any IP on any interface.should always have 2Mbps available to it.
One of our customers has asked us to Nat from the LAN to the Voice LAN based on destination IP address in order to access a public phone server through a vendor managed voice router..
Internet for everything else | | Inside ------------------------> ASA 5510 -----------------> Voice router ------> outside to public phone server only 10.10.1.0/20 10.10.1.7/320 172.16.20.1/24 Voice-------------------------> 172.16.20.0/24 172.16.20.254/24
Here the ASA5510 has an interface in both networks and the inside network can ping the voice network through the firewall by using non at acls. The phone server can only talk to the 172.16.20.0/24 network. So I need to nat the 10.10.1.0/20 network to the Voice interface on the ASA 172.16.20.254/24.
So I think I need the following static but I get the error below:
static (Inside,Voice) interface 10.10.0.0 net mask 255.255.240.0 WARNING: All traffic destined to the IP address of the Voice interface is being redirected. WARNING: Users will not be able to access any service enabled on the Voice interface. ERROR: Invalid net mask with interface option
have a question. I have a ASA5510 with IOS version 8.2 . I have my firewall and behind it also have a mail server eg 192.168.1.x. When i send email from inside network it doesn't show as if it's coming grom the out side nated public IP of my server but IP of firewall. What am i missing my example nat statements are . Nat-control is disabled.
I have an issue, of two parts. The first part I believe I have figured out, just the second part I am unsure of. I have an ASA 5510, currently, there is a mailserver that is static NAT'ed to one of my ISP routed IPs (not the IP of my main Dynamic PAT/Outside interface). I need to convert this over to PAT for ports 25,80,443, etc (standard ports). I know I need to remove the static NAT statement and add in the PAT statements, but I need traffic from that machine to continue to go out the IP assigned to it by the static NAT. E.G.
1.1.1.1 <- main public IP on outside interface, everything gets internet through this IP 1.1.1.2 <-> 10.10.10.10 static NAT to mailserver, secured with ACLs
I need to enable the mailserver to continue to appear to the world as living on 1.1.1.2, due to MX records and rDNS settings, etc...
The terminology for this setup escapes me at the moment.
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:
I got the charge of a ASA 5510 running with 8.3(1) version.Found that this is simple config with Patting for inside host and couple of Static Nat for web servers and FTP server as well.
There is lots of other configuration being done,I assume for the purpose of just R&D by the previous administrator.I need to understand if the following Nat statements holding any relevance?
Where we are running Only NETWORK_OBJ_192.168.0.0/23 subnet at inside and there is no other subnet defined in rest of the statements.i.e 10.0.0.0/27 and 192.168.1.128/27 doesn't exist at all.
I got a project where I have to provide NATTED addresses to cutomers for the internal servers and I found out that the outside address range /27 already in use. We are using 5510 with ver 8.1. We cant use PAT here.
At the moment if I try and access data from VLAN 1 to VLAN 4 it gets to the destination ok going through the static route and over the vInterOffice connection but the problem is VLAN 4 returning the traffic. This fails because there is no static route back to VLAN 1. If I create a static route from Office 2 to VLAN 1 then it will route all my data traffic over it as well.
I am trying to set up my ASA5510 the fail over of ISP when it can't ping three different IP. I create three different tracking to three different IP using sla monitor & track rtr. But when I do
the last route will replace the previous two and only the last route command takes effect.Is there anyway I can set up the fail over to ISP2 only when it can't ping three different IP from ISP1?
I have an ASA 5510 running version 7.0. I have a problem with an exchange server using a static map and its outbounc connectivity. It connects outbound through the global address even though inbound connectivity works fine through the static mapping. The recent changes are changing of the zero route through a different interface (there are to circuit connected to this ASA on different interfaces). So the idea was to get all workstations in the office using the global address and routing out through one circuit, and the servers connecting in/out through the other circuit. Shouldn't a static mapping ignore what the zero route is?
Here are what I believe to be the relevant configs.
interface Ethernet0/0 description New 6mb circuit speed 100
[Code]....
So exchang2 server can be connected to from the outside properly via IP xxx.207.51.231/exchange2-outside, but all outbound connections from this server are going out via IP xxx.122.47.218/circuit-6mb as do all the workstations due to the global address statement.
I am having touble with a NAT concept. What I have is a 3rd party software VPN product that basically tunnels encapsulated traffic to/from a server sitting inside the network. Right now this traffic utiluizes a physical interface on the ASA5510, but I need the interface for another project.
I am at a loss on configuring a new ASA5505 for multiple static port translations.I would have expected to simply add several service command to a network object to complete the task, however, the service command overrides the previous and replaces rather than adds to the translations. [code] However, if entered in that order the 8443 overwrites the 8080 static translation.What is the correct procedure to establish multiple translations? If someone could also provide the "old" style for pre 8.2 release, I'd like to compare because I thought I used to do this with an access-list somewhere.
I have an 8.3(2) ASA with a single outside IP. Dynamic PAT translates inside addresses to the outside interface address. I would like to use static NAT with port translation to access an inside syslog server. I got an error when I tried using the outside interface address. Can I use both dynamic PAT and Port Translation with the same outside address?This is what I would like to use but I receive an error saying there is an overlap using the outside interface address.(192.168.1.0 is my inside network. 10.10.1.10 is the outside interface IP.)
I have some problem with the ASA 5510 ver 7.0(6). My manager wants to keep this as backup. tried lots of things but still users not able to access internet nor can i ping anywhere.For example when i ping 4.2.2.2 i dont get any reply.The runing config is below for ur ref :
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).
I would just like to to open UDP port 123 in the ASA 5510 Firewall so that our Primary Domain Controller could use this port to sync time with an external time source. We have already added an access rule for this port under the firewall configuration in ASDM 6.4 and this port was also allowed in the inbound and outbound rule of the PDC's Firewall but it seems that it was still blocked.
I am unable to see 4th interface on my firewall i.e fastether0/3 on my firewall ASA 5510.

I've got an unconnected ASA 5510 running IOS 6.1 that I need to upgrade to 8.X (I believe 8.4 is available). The unit is a blank/default configuration and is not on any network so it can't be easily accessed via Ethernet. Is there a method that I can use its onboard USB port (0 or 1) to plugin a USB memory stick with the 8.X...bin file and process the upgrade that way?
I have not worked with ASDM in a while. I have a 5510, with asdm-645.bin in the flash. The device runs version 8.4(2). I can download ASDM from the http interface of the firewall from the management interface. But I can not log in. I have used blank username and password, no username and enable password, blank username with enable password and a few other permutations. I then tried to connect to the asdm interface from inside also. But I can not connect. Needless to say, I have enabled http, and updated the http access-list. The only logging I have enabled is buffered. Is there any configuration that I am missing? Shall I cut and past the config?

My problem is that I have 10 public address connected to ASA and each public address is redirectioned to an internal IP address. An of these public address is the ip address of mi ASA.
how to configure and access-list and an NAT, the others I will configure.

i have a asa with a outside IP address of 140.32.121.5. behind this firewall i have a cisco MWR 2941 that i would like to connect to via telnet. its inside ip address is 10.10.10.2. my reasoning for this is because i cannot SSH or telnet from a ASA so i need to have the ASA push my telnet request to the router on its inside interface.i have tried some NAT examples but i am very green with NAT. i have also built access lists that look like the follow " access-list 101 permit tcp any 10.10.50.2 eq 23. and then tied the access-group 101 with the outside interface. this also with no success.
I have a Cisco ASA 5510. I have detected an infected workstation on my internal LAN which has caused my IP to be blacklisted by Barracuda Networks and other RBL. I have scanned and cleaned the workstation removing the spambot. I want to prevent all my internal workstations from sending SMTP traffic on Port 25 through my ASA 5510 device. I only need to allow my Exchange Server access to send out traffic on port 25. configure this setup using ASDM 5.0? I know it may be easier using CLI, but using the ASDM would really be preferred.
I have a Cisco ASA 5510 appliance running ASDM 6.3 We have a number of public IP addresses associated with our company. In order to utilise the IP addresses effectively I want to use one puplic IP address for two servers running on different ports.e.g.
Public IP address 78.109.174.100
for both
Server 1 HTTPS and HTTP Server 2 FTP
Both Servers live in the same subnet (DMZ) I believe this maybe port forwarding but could be completely wrong. I've tried creating a NAT rule that goes from Server 2 Network object to Server 1 external but this didn't work.
We have an ASA5510 that we need to open port 25 to allow mail traffic to our internal Exchange server.We have 2 interfaces defined... one named Internal on eth0/3 ip 10.1.x.x and one named Internet on eth 0/0 ip 96.56.x.x.We followed the instructions in ASDM for allowing access to a public server but confusion over definitions have stopped us.ASDM asks for the internal interface and the internal server IP... no problem there because the internal interface and server have two different IP addresses. The Internal interface is eth 0/3 (10.1.1.1) and the server is 10.1.1.2.
However, when we get to the External interface (eth 0/1) there is only a single IP address 96.56.x.x but the ASDM asks for an Interface IP and the IP people would use to get to the mail server from the outside. Inasmuch as we have only 1 external IP address (which connects to our upstream Cisco router which in turn connects to the ISP modem) we used the same IP for both but the ASDM returns an error indicating they must be different.
Apparently we do not have a clear understanding of what the ASDM is actually asking for. When the ASDM asks for the external interface we assumed it was asking for the named value we gave the interface (which is Internet). The named value "Internet" has an ip associated with it 96.56.x.x. But when the ASDM asks for the ip people on the outside would use to get to the mail server (we created a named value called "mail server" and gave it the same ip address as the external named value. This duplication of ip address causes the ASDM to return the error stating that external Interface to be used and the external ip to be used cannot be the same.Have we made an error when we assumed that when the ASDM asked for the external interface it meant the ip of the external interface or was it asking for the eth number (as in eth 0/0) for the interface?
I'm trying to forward an internal service on a internal server to the external interface on the same port on the outside interface of our ASA.I been searching for a solution for days and found nothing.Here are the relevant parts of my config:
: Saved : ASA Version 8.4(2) ! object service TCP-WebServer-8080 service tcp source eq 8080 object network WebServer_Object_10.1.10.7 host 10.1.10.7
[code]....
So it looks like it's being dropped by an ACL, but it looks right to me.
I have a ASA 5510. I want to access the internal server IP through the ASA via http://60.54.x.x:8080/sms/DnNotify ( via port 8080).How do i configure it? NAT? ACL? configure port?
i´m trying to make a traditional port forward (http to http) on our new asa5510. Previous releases off 5505 and software prior 8.3 was no problem. Could someone tell me how do it in new 8.4 version? I ám a rookie on the new ASA series!
If nothing makes sense in this configuration please give example on how to do it correct. The object on the inside is SRV02 wich is running a webserver on port 80. So i want to open upp for http on outside interface and forward that traffic to srv02 (inside webserver)
