A customer got a new VoIP PBX, and now I have to forward port 443 on the ASA to the PBX for remote administration purposes. The LAN-interface of the PBX is in the same subnet as the ASA but has an external VoIP-router as default gateway and not our ASA. Is it even possible to forward the port to the PBX when there is no route of any sort to our ASA on it?

I've configured a number of remote access vpns on ASAs, but I don't recall having a default gateway setting assigned after logging in.
Is there a way to disable the assignment of a default gateway upon login?
The value assigned is meaningless. It's just the next available address in the local pool.
I'm trying to NAT to a device that doesn't have a default gateway; effectivley we want to talk to the device as if we're on the same LAN but using only port 80.Here's the setup:
Remote Device on LAN A <-> RA <-> Remote router WAN A <-> ISP <->--
--<->ISP <-> Remote router WAN B <-> RB <-> Remote Device LAN B (no default gateway)
We're using Cisco IOS on 877s and I'm sure this can be done
Does ip default-gateway have any effect on a L3 device such as a 2811 router? I always thought that on a L3 device the default route would supersede any such command assuming it is accepted.
We have a client device that cannot be reached for managment directly and wanted to add that statment only if it might work.
I am trying to get rid of 2 old 2651xm's and 2 2950's from my CCNA days and want to get into the ASA realm. Can I be able to use the ASA, not only as a security appliance / firewall, but also be able to write the access lists, etc, to be able to use this as my router to push packets to and from my internal LAN to the outside world? I guess I should have stated as this being the front end device to my network, just after my DSL Cable modem, that is..and being the only device. I am trying to have this as my main router /firewall solution and then I have an old Linksys router I will pipe off one of the L2 ports to have an AP for my wireless devices? Is this a real solution an ASA can provide?
View 2 Replies View RelatedWe have a setup where our e-mail server is hosted in-house.Our network is connected through a RV042 gateway. Port 25 is forwarded to our internal e-mail server.Our smtp service should be limited to receiving incomming connections only from 4 specific ip ranges which I set up in the firewall rules.The reason is that all smtp is managed and protected by an external anti-spam/vires provider.
However it looks like any computer is able to connect to our port 25 and be forwarded to our e-mail server.Does portforwarding overrule firewall rules - ie. you can not limit access with the firewall if you decide to port forward?Is this a "fixable" situation - or is the RV042 not built for handling this setup?
Currently a network consists of two subnets, one subnet is behind a ASA and the other behind a PIX, both connecting to the ISP's routers. If the PIX is retired, is it possible to create/consolidate the two networks protected by the ASA5510 with the default gateway being the ISP?
How can two private networks be protected by the ASA5510? One conceptual way is to create the VLANS on a layer 3 switch, on the "inside" interface of the ASA. In this senario what would the "inside" network's IP address? If the above is possible, how would natting occur?
Is there an efficient configuration to protect two networks protected by the 5510, other than creating a DMZ?
Is it possible to create two private networks with same level of security, 100 on a three network interface connections?
We have two ASA5510s, each with outside interfaces to the same two ISPs (different IP addresses within the same subnet, of course). Both ASAs allow ICMP on all (inside and outside) interfaces. One ASA's default route is to ISP-1 and the other is to ISP-2. We can ping the default gateways for both ISPs from only one ASA. From the other ASA, we can only ping the default gateway for the default route but not the other. The pings originate from an inside client, first configured with the default gateway for ASA-1, then for ASA-2. Why does this happen, how do I troubleshoot something like this and how do I fix it?

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.
Why when I try to reset Cisco ASA 5505 by pressing the button behind the hardware nothing happen? Just via software I can reset it?
I bought the hardware an year ago and I've never used, the problem that I don't have the blue cable and via software connecting to PC doesn't work.
I have an ASA-5510 in a location that loses connectivity to the wan gateway after anywhere from five to fifteen minutes. At first I thought that the unit might be defective, but I replaced it with an ASA-5505 with similar results. A reload of the ASA-5510 will restore connectivity for the next quarter hour.
Here's the version information on the 5510:
Cisco Adaptive Security Appliance Software Version 8.2(1)

I need to move the client machines off of the 3750 (and their DHCP dependency on it) to the SGE2010 and absolutely route their internet traffic out through the outside interface on the 5505. They must also be able to communicate back into the internal environment in order to communicate with the production servers.
The clients currently use .254 addressing through a dumb dell switch to the 3750 but I am trying to migrate them over slowly to the .253. I know that the 2010 will not do DHCP, so I am putting a DHCP server on that switch right now. The 5505 won't let me add an additional nameif statement onto one of the other eth0/x interfaces and I'm not sure if that has anything to do with it's capabilities to act as a DHCP server (it's not an option in the ASDM) or it's ability to serve as the internet gateway for the 2010 clients. (Side notes: The 5505 has a base license and is currently also connecting 1 site to site VPN. As is the 5520, so all of it's interfaces are used as well).
I statically assigned a moved client with a .253 address and plugged it into the 2010. I have tried giving the 2010 both a .4 address and a .253 address but neither will allow me to ping any of the addresses on the 5505. The 2010 shows automatic routes to the two subnets and I set it's default route to 253.1. The link between the 2010 and the 3750 works - clients receive a .254 address from the 3750 and can get out to the internet via the 5505 and reach the production servers as well.
Why won't the 2010 see the 5505 as a gateway and allow clients to get to the internet and also traverse the 3750 when they need access to the production network?
The reason why I dont' just connect the two swtiches and call it a day is because I also need the production servers to ALWAYS go out/receive web requests via the 5520 outbound/outside interface. I'm having such a hard time wrapping my head around why i can't get my clients moved over to the new switch, I haven't even grasped how I'm going to do that yet.
Within a workgroup environment we have four large drives, statically assigned and all accessbile via VPN. Our FW is a Cisco ASA-5505. Where within the ASA-5505 GUI can one of these drives be made inaccessible via VPN ?

View 2 Replies View RelatedMy little ASA 5505 is working great The device appears to be artificially crippled and limited to 10,000 connections. This isn't a "CPU limit" it's just some fake limit in the device as far as I can tell.
The problem we have is that we are only using around 500-600 connections and CPU usage is only like 25%, and yet the connection count is pegged at 10,000 and locks us out of our network.
I am pretty sure this is because there are a lot of "dead" TIME_WAIT connections hanging around not being used. In our application we only have the couple hundred connections but they do move around a bit every now and then.
Is there anyway to get the device to ignore the "dead" connections and not count them towards the artificial limit on the device given that it's pretty clear the CPU / etc., is not utilized sufficiently. These aren't real connections, we only have a couple 100 established, they do just move around a bit however.
We are really only using 500-700 connections according to our servers, the others are just sitting in TIME_WAIT doing nothing.
We have an Asterisk/FreePBX phone system located behind an ASA 5505 device where we are having problems with sip inspection.
We connect to three different phone providers, and things works as expected for 2 of the 3 providers,but for the last one (Draytel) we are having problems with sip inspection.
The key difference about the VoIP provider where we are having problems is that they are using differetn servers for the voice (RTP) traffic than the server we are registered with to establish SIP sessions.
sip inspection is configured with the default out of the box options.The problems we see are this:
1. For ingoing calls sip inspection does not open the required pinhole to allow the traffic to flow through. As a result we can not hear the voice of the calling party, but voice from our side is passed through ok.As a workaround we have added and ACE allowing traffic in the used UDP (RTP) range from this VoIP providers ip addresses to pass through the ASA, and with that in place incoming calls work.
2. Outgoing calls doesn't work because sip inspection doesn't kick in, and as a result of this we forward internal ip addresses in the SIP / SDP body to the VoIP provider. I'm not sure whether this is a consequence of sip inspection not kicking in for this provider, or a result of having added the ACE for an ip ragnge that covers the ip address we register with.
As stated above sip inspection does work as expected for two other providers where all traffic goes through a single server.We actually have had this working with ASA firmware 7.2(4), but as that version intermittently had a problem where sip inspection would stop working (fixable by power off/on or a clear command), then we decided to upgrade.
So here is my network.
ASA5505--->Cisco1841--->Cat2960
Code
ASA asa831-k8.bin
Cisco 1841 c1841-adventerprisek9-mz.151-4.M2.bin
Cat 2960 c2960-lanbasek9-mz.122-55.SE1.bin
and here is my dilemma.
I can SSH from the internet to my ASA on default port 22, directly to my public IP. I can SSH from the internet to my Cisco 1841 on port 2001. I can not however, SSH to my Cat 2960. From what i can tell, on the Cat2960 i can't change the default port 22 for SSH to different port, just like i did on the Cisco 1841. I looked to see if I can change the default port for SSH on he ASA, it does not look like this is an option.
The bottom line is that i want to be able to SSH to all three devices from the internet. I only have one public IP. As of now, what i can do is only SSH to the ASA on default port 22 directly to the public IP and Cisco 1841 on port 2001. It appears that changing the default SSH port on Cat 2960 is not an option. It also appears that I can't change the default SSH port on the ASA, if i could, i would and then i should be able to SSH to the Cat 2960 on port 22. No matter what i did on the ASA, it always listens on port 22 for SSH connections.

how do i make it listen on different port?

View 2 Replies View RelatedWe have a network consisting of a central site and a few remote offices. The sites are all connected via MPLS and also have VPNs over ADSL / internet connections as a backup. The remote offices have Cisco 837 routers for the ADSL connections which we can manage but the MPLS routers are managed by the service provider providing the MPLS connections. At the central site we have a Cisco 891 for the the MPLS connection (which we manage) and a Cisco ASA5505 for the backup VPNs.
In order to implement failover from MPLS to VPN in the event of any MPLS line going down I have tried to use ip sla monitors and tracked objects on the 891 as per Cisco's documentation. The problem that I am finding is that I can't set the number of ICMP echo failures required before the tracked route is dropped. Whenever the ip sla monitor fails to get a response the tracked route is dropped immediately. This is too sensitive as packets are occasionally dropped which results in the routes bouncing back and forth between MPLS and VPN too frequently (disconnecting users in the process).
I have tried different threshold types and values, tried configuring ip sla monitor reaction-triggers (although I don't understand what little documentation that I can find on this) and have even looked at event manager. I have been working on this for a few weeks now and am getting nowhere.
The Cisco ASA5505's implementation of ip sla monitor is much better in that it is possible to specify the number of packets but unfortunately we can't use the ASA as the default gateway for the LAN as the asymmetrical routing that occurs does not work with the firewall function of the ASA.
Any issue with ip sla monitor on IOS and managed to get it working?
