Cisco VPN :: 5505 - Dynamic IP ASA 8.3(2) To Static IP ASA?
Aug 22, 2011
Trying to connect a 5505 with a dynamic address on 8.3(2) to a static IP'd asa (5510 on 8.2(1) with a DefaultL2LGroup and dynamic maps already created.
Inside networks:
Local (5505) 192.168.100.0 /24
Remote (5510) 10.100.1.0 /24

I'm having some issues configuring NAT statements on my ASA5505 which has recently been upgraded to 8.41.
I have a single dynamic IP on the outside interface of the ASA and would like all internal hosts to NAT/PAT to it. In addition, I would like to have several ports 'forwarded' to internal hosts, one of which is TCP/4343. With the current configuration all hosts are NATing to the external interface properly but the service running on TCP/4343 is not accessible from the outside. See command output below:
"sh run object" output:
object network DrJones host 10.81.220.90object network LAN-10.81.220.0 subnet 10.81.220.0 255.255.255.0
"sh run nat" output:
object network DrJones nat (inside,outside) static interface service tcp 4343 4343object network LAN-10.81.220.0 nat (inside,outside) dynamic interface
"sh run access-list" output:

I wanted to move to the cisco arena, and having a bugger of a time figuring out simple nat/pat rules combined with access lists. I've been reading Richard Deal's Cisco ASA configuration book, googling the heck out of this simple problem and can't see what I'm missing.
I have an ASA 5505 unlimited security plus license running 8.2(3) and a simple network, 192.168.0.x internal, 192.168.3.x dmz (not even touching that yet!) and outside I have a /29 subnet of addresses, 25 is the gateway, and 26-30 are my addresses.
I have simple dynamic nat set up on the .26 address to nat to 192.168.0.x. All I'm trying to do is port forward a simple tcp port I set for my linux server (192.168.0.2) on the inside, for arguement's sake, it's 2222 (it's not really). My outside vlan 50 is X.X.X.226 255.255.255.248 , can I make a static nat (inside,outside) x.x.x.226 192.168.0.2 netmask 255.255.255.255 ?
I tried using (inside,outside) x.x.x.230 192.168.0.2 netmask 255.255.255.255 and that didn't work either. Is it not possible to use two external addresses to hit the entire /24 range AND a single server?
My access rule for this nat is permit tcp any 192.168.0.2 eq 2222 (where I'm using 2222 for my ssh port). then I apply that access list to the access group interface "outside".
I thought the outside interface would do a proxy arp (since I do not have the sysopt noproxyarp command) for my 227,228,229, and 230 addresses where .226 is my internal nat for all my internal machines i.e. 192.168.0.1 -> x.x.x.226 . I had this working like a charm before with my fortinet, so I know I have systems listening.

I'm working on setting up a template configuration for the Cisco ASA 5505 device that we'll use to configure more routers for various client needs. One of the requirements requested of me is the following: Internal hosts assigned a DHCP address are blocked from the internet Internal hosts with a static IP are permitted access to internet All internal hosts can communicate regardless of state
Now, I'm fairly new to this and I'm certain my terminology isn't correct so googling the problem has been fruitless. I have followed basic configuration guides and have configured the device to hand out DHCP addresses to hosts plugged in ports 1-7. If I'm plugged in and specify my address manually in the OS I am blocked from any access so I can only assume there is an access policy or some rule preventing me from authenticating against the router despite having set up VLAN1 to be the entire class C subnet. What sort of steps would I need to do to configure this? New access lists. For the record, the dhcp addresses are in the range of 10.100.31.64-10.100.31.95. VPN users are assigned an address from 10.100.31.220-10.100.31.240 and there seems to be no issues with that configuraiton. I don't wish to constrain what addresses a user can use should they specify a static IP (10.100.31.5 should be just as valid as 10.100.31.100).

I have an ASA5505 running which is on a static IP. I have just got an SRP527W for a remote worker and want to create a site-to-site VPN into the ASA. I have a number of other router of non-cisco brand which just all dial-in and connect no problem.
On other routers I have been abloe to specify the DDNS hostname in the VPN setup so that the ASA can identify it. I'm not sure how I setup the SRP527 to connect to the ASA.

I have some sites already connected with ASA 5505 site to site VPN with both end static IP. Normally, all traffic can come across without any problem. Even I used "management-access inside" for both ASA.Now I have a new office with only ADSL pppoe connection. I used easy VPN to connect from Site B:remote dynamic IP site to SiteA:static IP with similar example of this: [URL]
All my 5505 ASA are running 8.4(4)1
Site A - Static IP
Site B - dynamic IP with pppoe connection.
After EasyVPN connected, i do not know how do I remote manangment from site A lan to site B 5505 ASA?

Okay so I currently have an ISP that offers the standard "2 Dynamic IP's" and I'm wondering how to utilize this? The tech guy said I need a HUB...but I'm not sure what kind and where to get one etc. Secondly, even if I am able to get this second IP going, will they be entirely separate IP addresses? I need the IP addresses to be completely separate and untraceable to the same source. Is this the case or can you somehow trace back the two dynamic IP's to the same source IP? Will I need two different static IP's if I want the two connections to be entirely separate, unrelated, and untraceable from each other?

I am running an ASA with 8.4(3) and am trying to setup a dynamic VPN tunnel. We are having a business reason to establish a VPN tunnel to customers who do not have nailed down IP addresses. Now I found a number of documents that outline the steps involved. It seems the basic steps were to Establish a regular tunnelAdd dynamic crypto mapAssign the dynamic crypto map to the tunnel created under step 1. While this sounds pretty straight forward and simple, while prepping for doing just this I hot a road block while thinking it through. In order for my ASA to put anything into the tunnel it has to have a route to the remote network pointing at my VPN peer at the end of the tunnel. How do I do this in a dynamic tunnel? How do I add a dynamic route so the ASA knows which tunnel to stuff the traffic into? How do I stop the traffic from just being send to the Internet?

My dynamic ASA is trying to use a Cradle point 4G connection to a head end ASA-5510. The remote end with the Cradle point 4G is not even initiating the tunnel! I need another set of eyes. it was initiating the tunnel last week but not completing the connection. Now its not doing anything. i am going backwards. Below is my remote ASA config.
ASA5510(config)# sh run
: Saved
ASA Version 8.2(2)
host name ASA5510
enable password 8Ry2YjIyt7RRXU24 encrypted
password 2KFQnbNIdI.2KYOU encrypted
names
[code]...
I have a laptop directly attached to the inside interface. The PC and ASA can ping each other. The test interface is the one I am trying to use. Does my default route need to point to 192.168.0.1? Or is the remote peer correct? I thought the remote peer was correct? The 4G modem is like a pass-thru device. If I connect my laptop to it I can get out to the internet.

I've deployed L2L VPN between ASA's dynamic to static in a hub and spoke format.Everything works great if you are on a spoke ASA and you need to go to the hub but you can not go from the hub to spoke.
I'm using ASA code version 8.4(1) ... Below is what I have so far...
HUB
crypto ipsec ikev1 transform-set ts-dyna esp-aes-256 esp-sha-hmac crypto dynamic-map dm-dyna 65000 set ikev1 transform-set ts-dynacrypto dynamic-map dm-dyna 65000 set reverse-routecrypto map cr-vpn 65000 ipsec-isakmp dynamic dm-dynacrypto map cr-vpn interface outside
crypto ikev1 policy 10 authentication pre-share encryption aes hash sha group 2 lifetime 86400
tunnel-group DefaultL2LGroup ipsec-attributes ikev1 pre-shared-key *****
[code].....
Is there any way to apply a crypto map on the Hub side to encrypt the traffic to the spokes?

I faced up with a strange configuration issue at my 2811 router running IOS C2800NM-ADVIPSERVICESK9-M, Version 15.1(3)T. The configured Dynamic and Static NAT do not work (users can't go out to Internet and can't reach internal services via external IPs).The configuration seems to be very simple (one internal and one external interface, one address for dynamic NAT pool, and only few static translations -- see attached file).

Recently we migrated our network to ASA 5515, since we had configured nat pool overload on our existing router the users are able to translated their ip's outside. Right now my issue was when I use the existing NAT configured to our router into firewall, it seems that the translation was not successful actually I used Dynamic NAT. When I use the Dynamic PAT(Hide) all users are able to translated to the said public IP's. I know that PAT is Port address translation but when I use static nat for specific server. The Static NAT was not able to translated. Any conflict whit PAT to Static NAT?

in ASA 8.4, I need to use to static nat an internal IP with a public IP and use the same public IP to dynamic nat another internal IP:
-nat (inside,outside) source static IP1_PRIVATE IP_PUBLIC
-nat (inside,outside) source dynamic IP2_PRIVATE IP_PUBLIC
All outgoing connection from IP1_PRIVATE and IP2_PRIVATE should be natted to IP_PUBLIC and all incoming connection to IP_PUBLIC should be forwarded to IP1_PRIVATE: is it correct ?

Is it possible to configure a Site to Site VPN from a SA520 with Dynamic IP (DSL) to a Cisco ASA5510 with static IP? I need to make sure about because i am trying to sell this solution to a customer with two branch offices with DSL connection and a Main Office with Metroethernet.
I know that using a a pre-share-key on the defaultl2lgroup of the ASA, the ASA will accept any site to site VPN. I have tried this with the ASA 5505 instead of the SA500 for the branch office, but the ASA5505 is too expensive for my customer.

we are running 8.4(2) on the asa with the below configuration we basically have a static for .7 on .25 and a nat for .7 for port direction with manual nat that takes precedense over auto nat within the object group am I correct that I dontneed the dynamic statement and that its redundant?
-object network obj-10.X.0.25-02host 10.X.0.25
-object network obj-10.X.0.25nat (any,INSIDE) static X.X.X.7 dns
-object network obj-10.X.0.25-01nat (INSIDE,OUTSIDE) static X.X.X.7 service tcp smtp smtp
-object network obj-10.X.0.25-02nat (INSIDE,OUTSIDE) dynamic X.X.X.7

I have the dir-601 as my main router. Its IP settings are dynamic, not static. My second router, the router I'd like to use as the access point is a Belkin Wireless G Mimo. My goal is to setup the Belkin as an access point downstairs away from the main router. I'd like to do this wirelessly. I'd like to phsycialy plug devices into the Belkin, while the Belkin receives access to the internet wirelessly from my main router, the dir-601.
Here's my issue. There's an easy option to use the Belkin as an access point. So I do this and set the Belkin router to an IP outside the DCHP range ( currently 192.168.0.100 - 192.168.0.199 ) to 192.168.0.250. My dir-601 will only recognize the Belkin access point while plugged in physically. I know this because when I did a ping test it only see's the Belkin when plugged into the dir-601 via ethernet cables. My ultimate goal is to simply set the dlink dir-601 to recognize the Belkin as an access point.

I'm trying to combine dynamic and static NAT on a SR520. My dynamic NAT is specified with:ip nat inside source list 1 interface Dialer0 overload access-list 1 permit 192.168.0.0 0.0.7.255 In addition to this I want to perform static NAT for a couple of selected internal hosts. I can do this:ip nat inside source static 192.168.1.5 10.85.10.2 which works fine but means that the source address 192.168.1.5 is translated to 10.85.10.2 for all destination IPs. What I want is for the above static translation only to occur for a particular destination subnet.To accomplish this I have tried:
ip nat inside source static 192.168.1.5 10.85.10.2 route-map toOtherSite
route-map toOtherSite permit 10
match ip address 150
access-list 150 permit ip 192.168.1.0 0.0.0.255 192.168.10.0 0.0.0.255
But this does not appear to work. Instead it seems to render the host 192.168.1.5 unable to progress through the NAT, whether the destination subnet is 192.168.10.0/24 or not, and I can't work out what I'm doing wrong.

I am looking for an option to do the following. [code] Cisco 6509 with SUP2 with MSFC2 full mem
I would like the cleanest most stable option to allow this to work and still be secure with authentication. I know on the home side, I can just specify the remote ip and add a password. Not sure what can be done on the DC side to allow this to work properly.

I have a ASA5510 with 2 internal interfaces (inside1 and inside2 same security level) configured with OSPF for dynamic routing with 2 routers to corporate subnets. I have a server in a private subnet that needs to be accessed from Internet. So static pat is used in ASA with the command
static (inside1, outside) tcp interface www 192.168.1.1 www netmask 255.255.255.255
As OSPF is in use, the subnet 192.168.1.0/24 may be reachable from interface inside2. When I tried to configure the static command for inside2,
static (inside2, outside) tcp interface www 192.168.1.1 www netmask 255.255.255.255.the error message came out "WARNING: mapped-address conflict with existing static...". Is this just a warning, or this is not possible in ASA.

Do not have internet connectivity, despite all the lights lit on calbe modem and the ASUS WL520GU router and only the internet and ethernet lights are lit on the Linksys 2102.Despite numerous reboots, no change and even bypassing the router and connecting directly to ATA still no conectivity.When I open a browser, it reverts to the Asus error page, "reason for failed connection: You have set the wrong dynamic or static IP address, though nothing was changed.Funny thing again, a direct internet connection to the ATA did nothing.A google search only just shows lots of unasnered posts on this issue, or only the usual 'please reboot'.
