Cisco WAN :: ASA 5505 Remote WAN IP Change?
Dec 6, 2010
There is a site I oversee that is moving to a new ISP. The drive is 2 hours round trip and I need to do is change an IP. DHCP is being handed out by the internal Domain Controller and all the workstations point to the server for DNS. Will the following commands inputted over an SSH putty session into the current WAN IP change the IP and allow me to hookup to the new ISP? The plan is to copy and paste the following commands into global config mode. Currently they are using DHCP on the WAN side which I do not approve of and their external route is pointing to the internal IP of 192.168.1.1. Things still work but I want to do away with this. Will these commands get the job done?
interface vlan 2ip address 68.x.x.2 255.255.255.240exitno route outside 0.0.0.0 0.0.0.0 192.168.1.1route outside 0.0.0.0 0.0.0.0 68.x.x.1

I have an ASA 5520 with multiple site-to-site VPN's. A remote customer has changed their Public IP address and now the VPN has gone down. How can I easily change the peer IP of the remote site to the new one without have to put the pre-shared key in again as we don't know what it is and they don't manage their firewall.

Router: ASA 5510
We have changed the ISP, so therefore new wan ip-addresses.
Internet works, and site-to-site vpn works, but I'm failing to localice why the remote access vpn won't work.

One of the companies I work for uses a DIR 655 router. I'm having some trouble using FTP there.Initially the problem was that FTP software would hang or give errors when trying to change directories on the remote server. This problem went away when I switched from passive FTP to Active FTP.Now using Active FTP, the files appear to be uploaded with no problem. However, on closer inspection, the uploaded file has 0 bytes on the remote server.
We are uploading from a Windows 7 machine and uploading to our Web Hosting Company's Windows Server. I've actually written the one piece of software that is showing this problem but it uses a widely known open-source FTP library written in .NET. I've never encountered either of these problems with my software until I encountered the DIR-655.The other FTP software client I've tried is FileZilla. It has the same problem, 0 bytes files when using Active FTP.
One solution I've seen on DSLReports was to disable the Stateful Packet Inspection part of the firewall (known as SPI). This is really not a good solution for two reasons. Number one, I do not have access to the router's firmware/ configuration. Number 2, the company has a DIR-655 because they want the additional security. If we're going to disable SPI it just defeats one of the major purposes of owning the DIR-655.

I have four ASA 5505 devices connected via tunnels. All of the tunnels have a single point of exit to the outside, an AT&T T1 line. Because of issues with bandwidth, I added a secondary line to each site. In this case the secondary line is a comcast high speed internet connection. What I would like to do is set up a route so that any traffic that is going to the internet (browser or email) be directed through the Comcast line and all internal traffic (file transfer, ERP, VOIP) can be directed to the AT&T line. Each has a separate ip address. There is a single default gateway set up on the ASA now.

In default mode the ASA 5505 is setup with two Vlan's, one inside and one outside. Vlan1 is the default inside VLan, with IP 192.168.1.1. I would like to change the subnet of Vlan1 tot 192.168.10.1, but when I do, no Ethernet port is assigned to Vlan1 anymore (was 0/1 - 0/7). What I have done is;
#config t
(config)#interface vlan 1
(config)#ip address 192.168.10.1 255.255.255.0
But after that, no Ethernet port is within Vlan1, so I tried the following to assign one (port 0/1);
#config t
(config)#interface 0/1
(config)#switchport access vlan 1
(config)#no shut
But nothing happends when monitoring (#show run) interface 0/1 (no Vlan assigned)

I have successfully setup the AnyConnect VPN (connecting to our ASA5510) and have split tunneling configured. My remote users can access inside LAN servers as well as the Internet from their remote location. What I would like to know is is it possible to change the split tunnel and not allow access to the Internet from the remote location but force the remote client to go through the VPN and out our internal edge firewall to the Internet? Basically I need my remote clients to access the Internet but I would like for their Internet traffic to go through the VPN and out our edge firewall. This will allow the same security as if they were sitting in the office.

My company just assumed management of a remote entity. The network has several misconfigurations and I need to make some network modifications from my office w/o losing access or incurring lengthy outage to the clients. The network consists of 1721 router and three 2960 switches.
- I only have access to the router from the Internet. I telnet off the router to the 3 switches.
The site uses a single class C 192.168.1.0 / 24. The router is running RIPv2 even though this is the only network. The prior network person (contractor) set up separate native vlans on each switch and all the ports are defined as Native trunk and access are defined to the VLAN interface assigned to the switch. So of course the logs are flooded with Native VLAN mismatch, Each 2960 switch is a VTP server but has no VTP domain.
basic network layout:
Internet => Eth [Cisco 1721] => Fa 0 192.168.1.254 ==> [SW1]
[SW1]
interface Vlan1
no ip address
no ip route-cache!interface Vlan220ip address 192.168.1.219 255.255.255.0no ip route-cache
[code]....
!interface GigabitEthernet0/1description SW2 Gi0/1switchport access vlan 204switchport trunk native vlan 204!interface GigabitEthernet0/2switchport access vlan 204switchport trunk native vlan 204!interface Vlan1no ip addressno ip route-cache!interface Vlan204ip address 192.168.1.224 255.255.255.0no ip route-cache Normally, I would assign the current 192.168.1.254 to a subinterface to Router Fe 0/0 but with each switch having its own native VLAN I am afraid I will lose connectivity to the downstream switches -- my only access is telnet off the Cisco1721 Router.

I have created Remote access vpn on ASA 5505 (ver 8.2(5) with base license). When I connect from one machine, I can ping the internal network. But when I connect from another machine, cant.I have only decrypts on the ASA side, without encrypts. I was debugging ICMP packets with the capture feature, and saw that echo-reply packets are returning toward the outside interface, but aren't passing through it.
capture test access-list test interface outside
1: 08:54:44.298980 802.1Q vlan#1 P0 x.x.x.x > y.y.y.y: icmp: echo reply
Where x.x.x.x is LAN and y.y.y.y is the VPN client ip. The nat is ok, access lists are ok, but the packets dont pass through.I tried creating new VPN profile but the same problem, it seems that only one remote client can be active even base license allows more than 1 client.

I have 2 ASA5505 firewalls deployed, 1 at the data center (code v8.0.3) and 1 at a remote location (code v8.0.2). The remote location has 2 PCs that connect back to the data center to access the directory services, exchange, file servers, etc. The ASA5505 firewalls are configured for a site to site VPN.We were having stability issues with the remote ASA so we decided to upgrade the code as a first step. We updated the data center to 8.0.5 and all was well. I data was flowing and I could get into both ASAs from the data center via ASDM and ssh.Then I updated the remote location to 8.0.5. Now I can't ASDM or ssh into either ASA unless I'm at that specific site. PCs are still able to connect their servers.
I am unable to ping, telnet, ssh or ASDM into the inside vlan ip address while I am at the other site. I can see in the logs inbound connections being built on the distant firewall but it doesn't build a new outbound connection to reply traffic.Did 8.0.5 do something to block management connections from the outside?

Got a single asa 5505 configured in the office. we have 3 site to site vpn connections from this device, which all work from within the office.Ive not setup my pc to connect from home to the asa via the ciso client.
i can connect to all LAN servers on the local subnet, however i cannot connect through the ASA to any of my site to site vpn's.
if i do an ipconfig on my home pc i can see my local ip, mask & gw, and i can see my assigned remote access ip & mask but no gw.
I cannot ping any remote site to site pc's by IP or name.

I am currently having an issue configuring an ASA 5505 to connect via remote access VPN using the Cisco VPN Client 5.0.07.0440 running on Windows 8 Pro x64. The VPN client prompts for the username and password during the connect process, but fails soon after.
The VPN client logs are as follows:

We have an ASA 5505 and are changing ISPs so we'll be getting a new static IP address. How do I change the external IP address using ASDM? (I haven't done it in 5 years so I'm rusty and just want ot make sure.) The ASA and ASDM are up to date.Am i correct in that I only need to change the external address in the configuration under Interfaces, then under Routing - Static Routes - Gateway IP I just need to enter the new WAN gateway address?

We have a number of 5505 ASAs at remote sites all of which are configured to connect to one of two head-end servers.We need to change the primary head-end IP addresses. At the moment devices are successfully connected to the secondary.If we issue vpnclient server i.j.k.l e.f.g.h then the device drops off the network and won't reconnect until it is power cycled.If we make the changes in ASDM using the GUI to remove the old primary and add in the new primary the ASDM says "No changes made".Devices are running 8.2 and 8.4 code and behaviour is the same.
how to change head-end server IP addresses without the device disconnecting and not coming back up? According to the configuration guide the ASA should cycle through the addresses every 8 seconds until it can connect - but it doesn't seem to do this as it won't connect to the good secondary head-end either!

I just learned that the licensing structure for the ASAs is changing, but I don't have any details. We have roughly 30 ASAs (from 5505s to 5585s). If there's a licensing change, I need to do an impact assessment and plan accordingly.

I have set up two ASA 5505's (lets call them ASA1 and ASA2) with site to site VPN configuration and i've encountered two problems with my setup.ASA1 has IP 192.168.1.254 on the inside interface and is connects ASA2. It's also an Easy VPN Server for external users to connect through Easy VPN Client.ASA2 has IP 192.168.11.1 on the inside interface and connects to ASA1 Problem #1 None of the ASA's can ping eachothers inside LAN IP address. Computers behind the ASA's are unable to ping the remote ASA's inside IP address. My guess is that this has to do with either NAT or built in security.Problem #2. The Easy VPN clients which connects to ASA1 are unable to access the LAN behind ASA2.

We have 3 offices, each with an ASA 5505 as the router/firewall, connected to the cable modem
(NC office) <----IPSEC----->(PA office) <----IPSEC-----> (CT office)
Internally we have a full mesh VPN, so all offices can talk to each other directly.I have people at home, using remote access VPN into the PA office, and I need them to be able to connect to the other two offices from there.I was able to get it to work to the CT office, but I can't get it to work for the NC office. (What I mean is, users can remote access VPN into the PA office, and access resources in the PA and CT offices, but they can't get to the NC office).
Result of the command: "show run"

I have 3 networks coming from the DMZ (VPN) and only one works:10.132.24.0/24 Not working10.132.25.0/24 Not working10.132.26.0/24 Working The thing is, the one that works is on the same network as the DMZ(VPN) interface. The other two do authenticate and they get an IP from the VPN Pool. but they just cant access anything.

I try to configure a simple EzVPN infrastructure:
EzVPN Server (CISCO2811, hostname cme) < -- > EzVPN Remote (ASA5505, hostname ezvpn-asa) < -- > Client
Attached you find both configuration of the EzVPN server and remote. The tunnel is getting up and if I ping from the ASA to the Router, I see the packets getting encrypted:
ezvpn-asa# ping 172.16.100.1
...
ezvpn-asa# show crypto ipsec sa
interface: outside
Crypto map tag: _vpnc_cm, seq num: 10, local addr: 172.16.100.2
[code]....
If I connect a client with IP address 192.168.1.2 to the interface eth0/1 and do a ping to the cme, I don't see any packets getting encrypted. I don't have any idea about VPN, I just need it for a wireless lab environment. What do I have to configure on the ASA, so the inside traffic is encrypted?

I have not really set up ASAs nor VPNs on Cisco devices before. I'm currently attempting to configure a remote access VPN between ASA devices, a 5505 and a 5510. The 5510 is meant to be the server and the 5505 is meant to be the easyvpn client. The reason I am opting for remote access as opposed to site to site is that I have many 5505s at remote sites that I will need to configure in the future, and they will be moving around a bit (I would prefer not to have to keep up with the site-to-site configs). The 5510 will not be moving. Both ASA devices are able to ping out to 8.8.8.8 as well as ping each other's public facing IP.
Neither ASA can ping the other ASA's private IP (this part makes sense), and I am unable to SSH from a client on the 5510 side to the 5505's internal (192) interface. I have pasted sterilized configs from both ASAs below.
ASA 5510 (Server)
ASA Version 8.0(4)
!
hostname ASA5510
domain-name <domain>
enable password <password> encrypted
passwd <password> encrypted

I have an ASA 5505 that is on the perimeter of a hub & spoke vpn network, when I connect to this device using the VPN client I can connect to any device across the VPN infrastructure with the exception of the sub net that the client is connected to, for instance:
VPN client internal network connects to 192.168.113.0 /24 and is issued that ip address 192.168.113.200, the VPN client can be pinged from another device in this network however the client cannot access anything on this sub net, all other sites can be accessed ie. main site 192.168.16.0/24, second site 192.168.110/24 and third site 192.168.112/24. The ACL Manager has a single entry of "Source 192.168.113.0/24 Destination 192.168.0.0/16 and the "Standard ACL 192.168.8.8./16 permit.
