I'd like to create dhcp server pool on ASA 5510. I was wondering how big is the DHCP scope that Cisco ASA 5510 can support? Are there any ASA models which can support up to subnet mask 22 for DHCP scope?

I have a RV042 router. The problem that I am having with it is that the DHCP is giving out the wrong Default Gateway and DNS Server. There is no option to change the DHCP server IP on any of the settings pages on the router. I am begining to think that there might not be a way to do it. I see that there is an option for the DNS under the DHCP page but the Public IP that is being handed out is not the one on that page. I also have 2 WAN connections hooked up as well a DSL link and a Cable link (the cable link is the primary one).
The following information is provided in an effort to resolve this issue:
IP of Router 10.0.0.2
IP of DHCP Server (the one that is being handed out):10.0.0.1
IP of DNS (the one that is being handed out): 10.0.0.11
What I want to it be.
IP of Router: 10.0.0.2
IP of DHCP 10.0.0.2
IP of DNS 10.0.0.2
what this syslog message means? Being getting this on my 3945e series routers. My gut tells me they are caused by our Security guys scanning my routers with invalid login attempts.
%SSH-3-DH_RANGE_FAIL: Client DH key range mismatch with maximum configured DH key on server
My ASA 5505 has stopped giving out DHCP address to my machines.Everything was working fine and nothing has changed in the network. I've reloaded the firewall and clear all DHCP on the firewall I've even re-entered the cmd on the ASA.
I'm able to staticlly assigned address to the clients and all is way. When I do a DHCP debug on the ASA I don't see any events relating to the DHCP service apart from checking for lease expiry.
I've also tried to plug a machine straight into the ASA and no result. I finally did a packet capture and I am seeing the client machine sending out a DHCP discover packet and nothing else is responding.
My ASA config is:
dhcpd address 192.168.3.10-192.168.3.33 inside
dhcpd dns 8.8.4.4 interface inside
dhcpd option 3 ip 192.168.3.1 interface inside
dhcpd enable inside
I'm working in my lab trying to do proof of concept for traffic policing on the ASA 5510 running 8.0(4). I have two laptops running Ubuntu one on the outside and one on the inside. Both laptops have 100Mbps interfaces. My tests consists of downloading a file from one laptop using HTTP. Without any QoS I can see speeds close to 100Mbps which I would expect. On a side note, try using XP and you won't come close to those speeds. Anyhow, I implement policing using the config below and expect to see the max rate on the laptops during the transfer max out close to the CIR. However, I see speeds much higher on the laptops.
When I set the CIR to 10000 bps with bc at 1500 bytes I get speeds that range from 300Kbps to 700Kbps. I would expect to see speeds max out at the CIR which would be 10Kbps.I'm having a hard time understanding why my numbers don't match.
I have an ASA5510 where I have defined object-groups and then associated them with a specific ACL. Our ISP is pulling their point of presence from where I live and I am force to move to a new ISP. I am in the process of setting up another interface for the ASA5510 to connect to the new ISP.
My questions is can I create a new ACL lets call it new_access_in and use it with the same object groups that I have already defined? I know that I can only have one ACL bound to an interface, and will bind this new ACL to the new interface I am setting up, but I wasn't sure if I could use the same object groups and connect them to a different ACL. I really don't want to have to create new object groups if I don't have to.
I have an ASA 5510 and have just started using object-groups which are super handy in theory, but not working in reality. I have a service object-group with a mix of tcp, icmp, and udp ports. Let's call it Sample_Port_Group. I'm trying to apply it to my dmz_access_in ACL. Here's the line giving me problems:
access-list dmz_access_in extended permit object-group Sample_Port_Group 192.168.1.1 any
The asa throws up an error between 192.168.1.1 and any. When I put up a ? after Sample_Port_Group, it gives me the option of putting in an IP address, any, etc. When I put in a ? after 192.168.1.1, it only gives me the option of putting in an IP address.URL
Those posts gave me the impression my line was possible, especially the "access-list outsideacl extended permit object-group myaclog interface inside any" line, which is at the end of the 2nd article linked.
I had a virus. I think I got rid of it. Avast scans and boot time scans and Super Anti Spyware and TDSS killer report all clear. However, the network shield of Avast and the Internet don't work. Points to note: 1. In services, the DHCP and DNS cannot be started. I get the error 1075: service has been marked for deletion or one of it's dependancies are missing. (close to that)
I've checked the dependancies of both, and reinstated the ADF module in device manager after selecting the 'View Hidden' option.
So, I've set up Anyconnect client access to an ASA-5510.
I've got a handful of interfaces, which contain hosts that should be accesible to anyconnect clients. I'm unable to reach addresses on a specific network, due to what packet-tracer claims is an implicit deny, though I'm unsure where to apply an access-list in this case.

View 7 Replies View RelatedI find are steps to turn on SSH access. I have quite a few customers with ASA5510's installed. SSH is set up and working fine on every one. After a period of time, you are no longer able to SSH into the firewall. Using Putty, it just sits there on a blank screen without giving a "denied access" message or a login prompt. Rebooting the firewall will solve the issue and SSH access works again. Today, I had a customer with and active/standby configuration where I had to reboot both of them to be able to log in. Most of my customers are on 8.2.software as most don't want to reconfigure for the new NAT, etc.
I'm sure others have seen this before since it appears to be occuring on almost every ASA that I have access to. Is there any fix to eliminate this or is there something that can be run from the ASDM that will grant SSH access again without just doing a reboot?
I have to be missing something small in my config. If I upgrade my ASA 5510 which I am routing and Na Ting off of, from 8.4.1 to 8.4.2.8, SIP stops. All phones go dead.
If I roll back to 8.4.1, SIP comes up.,... Go back to 8.4(2)8 and SIP goes down.....
This is without making any config changes. I have looked at it so long, I must be overlooking something simple.

View 1 Replies View RelatedI know that I've run into this before but I can't remember the fix. I have a 5510. The 3 interfaces involved are INSIDE, OUTSIDE, and GUEST. Corporate users are allowed to put their iPhones on the Guest network, but the problem is that their Exchange ActiveSync stops working. It is tied to the external DNS name of the OWA server (we'll say webmail.abc.com). So the users are funneled out one public IP on the OUTSIDE interface and are trying to communicate with the outside of the OWA server, which is NATed to another public IP on the same outside interface. What do I need to do on the ASA to allow users on the guest network (behind the GUEST interface) to access the mail server using its public IP (behind the INSIDE interface)

First connect to Verizon, then it automatically launchs ATT Global Network Client, once connected, the system automatically maps drives. I stay on for about 15 minutes average to 40 minutes that's when the Verizon drops/disconnects. This consistantly happens throughout the day!
1. If I connect to a "local" wireless signal NO dropping.
2. If I tether my Sprint Android, NO dropping.
Only dropping with the Verizon. I MUST have the Verizon dedicated to this work computer to run the VPN and hopefully (very soon) a mandated VOIP with Avaya!Called Verizon- they sent me a new USB thinking that might fix it. But same thing. They are showing signal strength 4G. Nothing on their side.
