I have a very basic question about Cisco ASA 5505 IPsec Site to Site VPNs. I want to install a Cisco ASA 5505 at a Data Center, in a LAN subnet that utilizes publicly routable IP addresses. I would like to install a second Cisco ASA 5505 in a remote branch office as its peer.
Regardless of whether I use publicly routable IPs at the branch office in the "inside" network or non-routable IPs, how would the devices and servers at the Data Center know to route IP packets destined for the branch office back through the Cisco ASA instead of through the default gateway at the Data Center? I can see accomplishing this if every single device at the Data Center is configured with routing table entries, but that isn't feasible. It also isn't feasible to use the Cisco ASA 5505 as the default gateway for all of the devices as the Data Center, allowing it to decide where the traffic should go.
Is the solution to try to map branch office IPs to IP addresses within the Data Center's LAN subnet so that all of the traffic is on the same subnet?
Have a number of organisations that I work with who are currently all changing their ISP to a different one. The company who are supporting this are introducing a new router and firewall to the network and removing the old layer 3 switch. Firewalling and filtering was previously done off site but will now be handled by the ASA 5505. I personally do not have permission to configure the ASA (nor would I know how to) So these places are set up with 2 ip ranges, so int 0 on the ASA is 10.0.0.1, int 1 is 10.0.1.1. The Cisco ASA has been configured with the same settings on it's required ports as the old layer 3 switch had, so nothing much has to change on the internal network. Problem is that the old layer 3 switch must have only been passing data through at layer 3, so basically not switching and not creating networking loops. It seems that due to certain required network topologies, switch A is connected to switch B, which is connected to switch C, which is connected to the ASA, but switch A will also be plugged into one of the interfaces on the ASA (creating a loop). As I've said, this was not a problem with the layer 3 switch but now the ASA must be switching at layer 2 (I guess...?) as well as routing to the internet (which is required for both ports, which are vlans) and so is messing up the lan with a switching loop.
can the ASA 5505 be configured so as to allow access to the internet for both vlans/ip ranges while also preventing switching loops being created? It seems definite that this is being caused by the introduction of the 5505 as the old setup was exactly the same, it's just that the 2 cables have been plugged into the 5505. We do not have the option of using STP here as the rest of the switches on the network are unmanaged.
I assume 10-user means this device comes with a 10 user VPN license? Is there anything else I should be looking for when purchasing an ASA? Mainly looking to use my NetGear WNDR3700 as just a WiFi AP and not my edge device.
I am planning to imlpement an ASA 5505 in my home network and I am wondering if this is a valid configuration. I am wondering if it is necessary to have 3 separate internal subnets or if these can be cabeled together in a more efficient fashion?
I plan to keep the 2 servers (game, e-mail) branched off the ASA directly in a DMZ configuration. The rest of the clients connect through the wireless/wired router.
Any unforseen problems with a setup like this (Modem -> Firewall -> Internal Router)? I have read sites that say I will have to accept an IP via DHCP for the ASA's external interface.
I recently installed a very basic version of XP on my old laptop (Gateway MT3707).After hours of searching for the correct drivers, I found them, and installed them. After installing the correct drivers for wireless internet I was able to pull up the list and find my network on it.When double clicking on our wireless network it asks for a network key (also called WEP key or WPA key).Now we have a password for our network, but after an exhausting amount of tries that won't work. I not sure if that is what its looking for. In our apartment we run mac OSX, windows vista, etc., but usually the password for the network is satisfactory. I have never ran into this problem.I hate to be a noob, but I don't know where to go from here.
I'm trying to determine what switches in the Procurve lineup will do Inter-VLAN routing on the same switch. Assume a basic 1 switch network.
I've determined that Procurve "Layer 3 Lite" will do static routing but not dynamic routing. So I would assume their Layer 2 switches do absolutely no routing. However I have a 2520 in front of me that HP claims is Layer 2 only yet I can route between VLAN's on that switch.
A month ago my ISP was routing half my subnet (129-254) over DSL. I just moved and routing no longer works without NAT. The issue is probably with the new DSL 'modem,' a zhone 1611-A1, but I am not sure how it should be configured.The 1611 is connected to a WRT610N, which works in NAT mode with the following settings:[code] With the previous settings, networking doesn't work from a workstation, though I can traceroute from the 610. I would like all workstations on the "LAN" to have fully addressable internet addresses like the previous configuration.There is an admin interface on the 1611, but the cursory settings I've tried don't work and I'm not a routing expert. The ISP is kindly routing my network, but they don't provide much support.
Having some serious problems on the networking front here at home. I have 3 PC's and 2 Xbox's that run constantly. Our Internet bandwidth is Insight's 50.0 which is 50Mb download speed 5Mb upload speed. The problem we're having is this. Ever since we upgraded from dual 20Mb lines on a Cisco RV042 to a 50Mb on a DIR-655 we've been having latency issues. I have everything turned off in the router. It's basically there to give out IP numbers and thats it. All security is handled from the PC's themselves. Bandwidth tests are fine, I sustain download speeds above 7MB/s using download managers. But pings are terrible. Xbox live is terrible, PC online gaming is terrible. Pingtest.com is terrible. Only when behind routers. I've tried it behind 3 seperate routers. The DIR-655, the Belkin f5d8236 that insight provided me, and the cisco rv042 originally used for dual wan routing. all of which are met with serious failure.
If I plug directly in to the modem pings are fine. Add a router and pings go to shit.
We have two Cisco 5505 firewalls connecting to two ISP's . The two internal LAN's on the firewalls are 192.168.184.0/24 & 192.168.186.0/24. We also have a Cisco C3560x layer3 switch with vlan interfaces 184.3 & 186.3. We have two DGS-3100 Dlink layer 2 switches connecting our users to the Layer 3. Ip routing is enabled for intervlan communication & I can reach the Switch interfaces & firewall gateways from machines on both on the vlans.We have pbr enabled on the 3560 & users only on the .186 network can get to the internet. The switch is running the ipservices license & the sdm template is "desktop routing" .
Users on the .184 cannot access the internet but we can ping the layer3 interface & the firewall gateway. [code]
how do i configure the new asa 5505 to be as a router as shown in the diagram note: the isps' routers placed in head office. but i cannot change the configurations of the isp's routers.
I am new to the ASA so I am not completely familiar with it's ins and outs but here is the situation.I have a VPN connection that my company uses regularly. I have the VPN Pool on 192.168.18.0/25 and my Internal network at 192.168.16.0/24. My problem is that I have my phone system on 192.168.16. 254 and the only way to see it is if I change the pool to be within the same IP range as my internal network. The catch is that if I do this then that is the ONLY IP that is available to that VPN connection. Is there a way to make the 192.168.16.254 available to 192.168.18.0/25?
I have a CIsco ASA 5505 with the default license that only allows the use of 3 interfaces (inside, outside, DMZ). I'm already utilizing all 3 but I'd like to configure the AnyConnect Client VPN stuff. I know with solutions like OpenVPN you can configure it to use NAT instead of actually giving it an interface with a different network and configuring routing.
I am just about to buy ASA 5505. I need outside interface with Public interface that can NAT to two internal (priv)( networks. Can I have two inside interfaces, like192.168.1.0 and 10.2.0.0 that can talk to each other? Can I do it without vlans? Reason why, I would need to reconfog my current switches. On cisco web they saying that: "With the Base license, the third VLAN can only be configured to initiate traffic to one other VLAN" - but I need two inside netwroks be able talk to each other.
I have Cisco ASA 5505 Firewall with security plus license. I want to Configure 3 different subnet for inside network 10.1.x.x, 10.2.x.x and 10.3.x.x So any PC from 10.1.x.x should be able to ping 10.2.x.x So my question is that possible with ASA?? If yes than how can i configure on ASA 5505, as i know on 5510 we can configure sub interface and do intervlan routing.
I'm fairly new to cisco and the ASA 5505 I have the asa connected to the internet on 0/0 I have a computer connected to port 1 and on port 2 I have a netgear router. the asa is 192.168.1.1 and the netgear router is 10.1.5.1 I cannot get the computer connected to the asa to communicate with the devices on the netgear router and visa versa. Here is the show version.
I have an ASA 5505 and I have the three regular vlans, outside, inside and dmz. The best would be only have outside and inside and skip dmz, but without explenation there is not possible to have more then two clients in whats now dmz because of a mac filter on third party device.
So as security is concerned dmz and inside is equal, one to one and there should be full access between them. I ran the wizard and said that the only way traffic not should be possible to flow is from dmz to outside.
In the NAT rules the onle rule is global (outside) 1 interface nat (inside) 1 0.0.0.0 0.0.0.0
But traffic from one way or the other dmz to inside, og inside to dmz it says in log
3Dec 06 201215:38:39305006172.17.6.1053portmap translation creation failed for udp src inside:192.168.6.102/49358 dst dmz:172.17.6.10/53 From documentation I have an image with network drawing from documentation. What do I have to do allow traffic btween inside and dmz, both ways.
we want to make another subnet, which we plan to use for all our network printers for now( other use in the future) PCs at 10.1.1.X will be able to print on the new subnet. the new subnet will be able to connect to the internet.
What's the best options we can do for the subneting? how can we configure the router? is possible to set another DHCP on the new subnet. we currently have one DHCP on the 10.1.1.X
I have a Cisco ASA 5505 that has been configured to act as a router as well. I have configured 3 VLANS that have access to the internet. For some reason the "InsideWifi" and the "Guest" VLANS have very slow internet speeds and sometime web pages wont finish loading properly. The "Inside" VLAN gets the speeds that are expected. The DNS server does reside on the "Inside" VLAN. Is there anything wrong with my configuration that would cause the internet speeds on the other VLANS to be slow? My config is attached.
I'm trying to configure an ASA5505 behind an ADSL modem/router in bridge mode.The problem is the routing on the WAN side, because the gateway/next hop is a wierd address on the 10.x.x.x. range, outside the subnet.
So, I've got bridge mode working fine. If I take a laptop and configure it's ethernet adapter as the ADSL public IP with the wierd default gateway of 10.20.20.224 - windows complains about the gateway being outside the interface subnet but allows me to apply it, and it works, the laptop routes out to the internet fine with it's interface on the ADSL IP address.
So the bridging would appear to be working fine, negotiating the PPPoE ADSLand routing that transparently to the ethernet ports.But when I plug the ASA into that port and configure the ASA interface on the ADSL IP, I can't get it to route out properly.
With the ASA in this configuration I can't even ping from the ASA on the outside interface to 10.20.20.224 and get a reply. With a PC running Windows plugged into the same port on the same IP and the same gateway, I can ping it (and route out) just fine.
When in bridge mode the ADSL modem/router assigns a managament IP to the ethernet interfaces of 192.168.1.1, so you can still connect to the device to manage it. If I change the 'outside' address of the ASA to 192.168.1.100/24 I can then ping to 192.168.1.1 and get replies, so the physical connection is fine.What am I missing here?
There are three different sites, two are composed of Multilayer switches cisco 3560 and 3570 as core switches (a 3560 in one site and a 3570 in another site), the last site doesn't have any routers just a 2950 switch. Each site has two asa 5505 as firewalls. Two Internet connexions are connected to every site, one on every firewall. One Internet line is used to connect the different sites together using VPN crypted with IPsec and the other line is just for Internet access. The line that is used to interconnect sites contains voice and data traffic.At the moment all the routes are static routes, the network isn't too big for now and counts not more than 20 subnets.But it is evolving, and I want to use dynamic routing, EIGRP to be more accurate. I've looked into it and I'm not sure how to make it work. The VPNs active on the ASAs don't support dynamic routing, so I thought about GRE tunnels but the ASAs don't seem to allow it either.
I am new to Cisco ASA and have been configuring my new firewall but one thing have been bothering. I cannot get internal networks and routing between them to work as I would like to. Goal is to set four networks and control access with ACL:s between those.
1. Outside 2. DMZ 3. ServerNet1 4. Inside
ASA version is 9.1 and i have been reading on two different ways on handling IP routing with this. NAT Exempt and not configuring NAT at all and letting normal IP routing to handle internal networks. No matter how I configure, with or without NAT I cannot get access from inside network to DMZ or from ServerNet1 to DMZ. Strange thing is that I can access services from DMZ to Inside and ServerNet1 if access list allows it. For instance DNS server is on Inside network and DMZ works great using it. [code]
The ASA is the gateway router at .1 for the LAN and DMZ networks. On the WAN network, the ASA occupies .85 and uses .86 as it's gateway to the Internet. Clients on the LAN are able to access the Internet without any troubles. I have a static NAT setup to map the DMZ server's 172.30.200.81 address to 10.0.0.81. I also have a general NAT that should allow other servers on that network to access the internet, but no machine at all on that network can route outside of 172.30.200.0/24. I used the packet tracer and had it trace traffic coming from the DMZ network to the Internet, and it did not show me any conflicts with any of the access lists or anything else. However, no matter what I do, I cannot initiate traffic from the DMZ and have it go out to the Internet successfully.I attempted to follow the directions in the article PIX/ASA 7.x and above: Mail (SMTP) Server Access on the DMZ Configuration Example; but I have obviously missed something, done something wrong, or perhaps the example assumes something about my configuration that I have not done. See the attached config file that I have scrubbed. I have removed VPN configuration information and other unnecessary parts of the config file to make it easier to read. I have setup an ASA 5505 w/ Security Plus with three subnets. The subnets are as follows: VLANSubnetWAN 10.0.0.80/29LAN192.168.1.0/24DMZ172.30.200.0/24 ]
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.
I have recently inherited a few networking responsibilities in an SMB network. Nothing overly complicated. Here's my issue, there is an ASA 5505 used for VPN and in the near future a DMZ. I can connect via the console but I'd rather use ASDM. The problem is that I can't get it to connect. VLAN 1 (Inside) has an address of 192.168.200.254. This is in ethernet 0/0. I have a laptop plugged into ethernet 0/4 and the laptop has an address on the same x.x.200 VLAN. I can ping the VLAN1 address, but I can't use http://192.168.200.254/admin to get to ASDM.
how I can do this? What I should check? Can the internal webserver that hosts the ASDM be turned off?
Ive been readin all over the internet (including this site) trying to figure out if the asa can handle intervlan routing. Im not sure what I am missing on my config to get this to work. Ive read that it can work and Ive read that it cant work. How to get this to work on my asa 5505.
Here is my setup
Cable Modem ---> ASA (eth0/0) (eth0/2) -->unmanaged switch for LAN connectivity (eth0/3) --> Access point for wireless LAN connectivty
My config is attached
What I would like to do is be able to communicate between vlan3(LAN) and vlan4(Wireless LAN)
Whats strange is I can RDP between the two vlans but I cant ping or anything else.
my ASA 5505 just woke up one day and didnt allow me to login to it with ASDM. i can console in though but telnet, ssh and asdm will not work. it just times out.
VLAN 100 with 192.168.100.0/24, default gateway 192.168.100.254 VLAN 110 with 192.168.110.0/24, default gateway 192.168.110.254 VLAN 120 with 172.16.0.0/16, default gateway 172.16.10.254
From the different VLANS(100,110,120) I am able to connect to all devices in the other VLANS (except for Native VLAN 1; it's not pingable)From switch cli I can ping my firewall (192.168.1.1) and all other vlan gateways and vlan devices (VLAN1,100,110,120) From asa cli I can only ping my switch port (192.168.1.254), but no other devices in the other VLANs.
What do I need to change or setup in the switch or asa configuration in order for the other vlans to access the Internet through the ASA. I will not use the ASA as intervlan routing device, because the switch is doing htis for meI tried changing the asa int e0/1 into trunkport (uplink port on switch also), to allow all vlans, but as soon as I do that I cannot ping to 192.168.1.254 from ASA cli anymore.
On the downloads page there's a 9.0.2.ED listed as the 'latest' but then if I expand the '9' below it I get to 9.1.1.ED. Which one is the actual latest? is there any way to tell the one that is not an 'interim' version I think 9.1.1 is also listed under interim?
We need to connect from an external computer connected by cisco-vpn-client to one internal server that is behind an ASA 5505 config with Easy VPN. The VPN connection with the client to our 5520 firewall is fine, but when I try to connect to the server on the LAN, FW log says:
Routing failed to locate next hop for TCP from Internet:172.17.1.215/1108 to Lan_Interna:172.33.0.50/3389 Attached image.
I have an ASA 5505 at each of three locations. We have VPN tunnels set up between the three sites. I am currently using a single ISP to control the traffic between the sites. I am adding a new ISP to the mix. The goal is to have any internet traffic routed to ISP 2 and all internal traffic routed to ISP 1.The ASA does not do policy based routing (mostly because it is a firewall, not a router). I need to configure a router that will accept the output of the ASA and route it according to the above rule. All incoming routing will be done through ISP 1. Any suggestion on the device and the methodology to set it up? I am planning on doing this in each location.
