I read a number of older posts indicating that there was no ability to walk the arp table on an ASA 5510; wondering if that has changed at all?
Is there a syslog message that is generated when a new arp entry is added? Is that the only way to do this is to programmatically ssh into the ASA and grab the output from a 'show arp' command!
I am trying to setup an ASA 5510 for anyconnect. I was using the document: [URL] which looks the same as:[URL] I get to step 3:Click Configuration, and then click Remote Access VPN.Expand Network (Client) Access, and then choose SSL VPN Connection Profiles.
There is no SSL VPN Connection Profiles.It all goes downhill after that.Show version shows:

I'm trying to determine whether Cisco has any equivalent (in any platform) to some of the existing firewall rules within our iptables infrastructure. [code] What this does, is allow port forwards on port 3389/rdp. However, if a single IP opens too many connections within a timeframe, it starts dropping new ones.This is a critical requirements for certain security scenarios, such as preventing RDP brute forcing. A similar principle can be applied to 22/ssh.I've had a look around, rate limiting searches generally land me on QoS based discussions. I've seen people ask similar questions and get referred to CBAC. Whilst I can see similarly worded functions there such as limiting "half open" connections, I don't see anything there that limits the actual number of connection attempts you can make.
View 1 Replies View RelatedWe have an issue in which some of our public IPs will not work from outside. We have a couple of subnets/29. We allow traffic via access rules and they point to internal servers (nat to nat). So I requested an ARP table from our ISP router. The table shows that the non working IPs have a differect MAC address than the working IPs. Our ISP blames our equipment (CIsco ASA 5510) for this. I spoke to Cisco support. They looked at our configuration, and tested it. They say our configuration is correct and the ISP's equipment is doing it.
IPSMAC address*.*.*.5*.*.4cd8*.*.*.4*.*.4cd8*.*.*.3*.*.4cd8*.*.*.2.*.*.4cd8*.*.*.204*.*.4cd8*.*.*.205*.*.4cd9
As you can see above, the IP ending in 205 has a different MAC address ending in 4cd9. It should end in 4cd8. This seems to happened randomly with all IPs. Like if I restart the ASA. Some of the IPs will not work, and will show a different MAC address.We then have to wait a couple of hrs for them to start work again.

I'm attempting to configure two ASA 5520 for active/standby failover.When I enter the “failover” command to enable the config on the primary ASA, the entire routing table disappears.There is no routing process running, only static routes are configured.
Is this an expected behavior of the failover process and if so, how long should I wait for the routes to come back?

View 1 Replies View RelatedI have Windows 7 64 Bit Pro PC connected directly to the router via Ethernet.This is I will call Ethernet Connection 1.I also have a Windows XP Pro SP3 computer connected to the same router but via a wireless connection.I have both PC's connected together via an Ethernet cable. This I will call Ethernet Connection 2.It all works fine, but I only want my PC's to communicate via Ethernet connection 2.Currently, if I disconnect the Ethernet cable between the computers I can still access the files on the Windows 7 computer via the wireless connection on the Windows XP computer.I've tried to see if this is discoverable by other people using the router by installing Ubuntu on the Windows XP machine and looking at the available networks. Lo and behold, my Windows 7 machine is discoverable and accessible - albeit by a password. This is with the Ethernet cable between the computers unplugged.I have both networks on the Windows 7 machine set to public and all sharing options switched to off. Both computers have the same workgroup name. Worryingly I can still connect to the Windows 7 machine via Ubuntu wirelessly without even using the same workgroup name!All I want to do is connect the two computers via Ethernet Connection 2. I don't want any sharing information going to the router too and hence other poeple being able to see it. Ethernet Connection 1 on the Windows 7 machine is for the internet only (same as for the wireless connection on the XP machine).

View 1 Replies View RelatedI have one Cable Modem/Router built in (Netgear CGD24N) and I wish to use two routers (the other being the DIR-655). The Netgear is a fantastic Cable Modem but a ****py router, but I wish to use both. One will be situated upstairs and the other downstairs.I have connected the two at different locations via the wall and the DIR-655 successfully went to the Netgear login page (as I went to 192.168.0.1) but internet connection was not working, whereas the Netgear internet was working. This was connected LAN to LAN.
Another procedure I have tried was connecting to them LAN - INTERNET (INTERNET being the D-link one) and received the following message: "The addressing of the Internet side learnt thru DHCP conflicts with the addressing selected for the LAN side. Internet communications will be disabled until you have changed the LAN side addressing to resolve the problem."
I currently have a Cisco 3945 router deployed and I am reaching the CPU's max during peak usage. The 3945 supports ~500Mbps Fast/CEF Switching and I need something at least double that capacity.
I need the ability to have at least 8 RJ-45 10/100/1000 connections. I also need the ability to NAT.
Ok I realise that the 825 doesn't have the ability to create static LAN routes. Is there a workaround or is this somthing that may be implemented in the future. It's a real let down to find this feature missing in an expensive router such as this.

My XP Pro SP3 PC is connected to a Netgear DG834N modem/router via Ethernet. If the PC is left for say 4-5 hours the ability to connect to websites disappears. The browser just hangs and it's the same with IE and Firefox The odd thing is I can still ping websites by domain name without trouble. So the interenet connection is actually still in place.The problem is consistent and repeatable.Throughout this I have a second XP Pro SP3 PC also connected to the router via Ethernet and it works perfectly.

I have a video conferencing device and I struggled a lot with a bunch of different routers. I was giving up but then I plugged in a friend's old Linksys/Cisco Adsl gateway and all the problems disappeared (kudos to Cisco). The problem is that the gateway is not ADSL2+. I have since borrowed a Linksys/Cisco ADSL2+ router, however, there isn't a possibility to enter port speeds/duplex manually (required to prevent packet loss in video conferencing, I really want to have that option for the peace of mind). I have been looking around on the internet but I can't seem to find this ability any routers' specs. What I need is as follows:
- Has to be Cisco or Linksys router
- Has to be ADSL2+ (Annex A)
- Doesn't have to be wireless, even single port is OK
- Preferably has DMZ
- Ability to hard code lan port speed/duplex (i.e. no autosense)
- No other functions needed so hopefully a cheap option
We recently had redundant sup cards installed in 2 of our 4507 units after the upgrade I can no longer change Vlan's with the CNA program.I upgrade to the newest version of CNA but that didnt work.
I can still get Vlan information from my 4503's and 4506's with no problem. I figure it is an issue with CNA selecting the sup card to get it's information from?
We are in the middle of some major user moves and changes so I have had 2 of my guys working to move printers on to their own Vlan and some other changes neither is well versed in command line so I set them up with CNA for simple Vlan changes. Now with this out I have to go in and make the changes myself and keeping up with that and my other duties is getting tough.
I picked up this RV180 router because it has one of the fastest thru speeds of all the routers tested that I viewed on smallnetbuilder. That and it has the cisco name. I grew tired of purchasing wireless home routers every year after they fail. So far the thing is nice with one exception.
I have one device that is essential on my network called an airave. It is a small device similar to a wireless access point that works on springs voice network. The thing essentially makes a small cell tower inside your house and connects to the sprint network through an Ipsec vpn. I have not ability to change ipsec settings on the device on my end. The device works fine connected to the cable modem or to the old slow dlink. When I first connect the thing it works fine for about 5-10 minutes on the cisco. Then the thing loses connection and I lose my cell phone service. Just to test any port conflicts I made this the the DMZ with no luck.
I have also tried a firmware upgrade. I have not messed with any of the firewall settings or port forwarding since DMZ should in theory fix that. I have assigned the thing a fixed IP address but that does not seem to make a difference. It did not on my old router and is mostly just for my sanity and to facilitate the DMZ.
Can the quality of my phone line affect the ability of web pages to load? Some times web pages load flawlessly at other times browser says web page found but it refuses to load. I assume that things could get slow if I am downloading various updates in the background. What could be my problem? My phone line is on poles-underground-been spliced and on the end of the line. Seems like when I need to connect I can't.

I need to create a firewalled segment that not only separates hosts from general population, but also from each other. The solitary confinement of firewalled segments.I know that I could create a bunch of sub-interfaces, one for each host or group that needs to be isolated, but I'd really rather not have to do that if possible. 1) It could become a management nightmare between ACLs and sub-interfaces and 2) it's a waste of IP addresses.s there any way that I can create a bunch of separate VLANs behind the firewall and have them all terminate at the firewall, using a single firewall IP address for the gateway?
VLAN 1 - hosts 1.1.1.5 and 1.1.1.6VLAN 2 - hosts 1.1.1.7
Firewall DMZ Interface - 1.1.1.1VLAN 3 - hosts 1.1.1.8 and 1.1.1.9
This way, the hosts are isolated and can't talk to each other unless they're on the same VLAN.I'm working with an ASA 5510 running 8.2.4(4).
