i am running a vpn between three remote offices, by making use routers that get dyndns. I would like to substitute the existing routers with Cisco 877/876 to get better management. How to do a tunnel by making use of dynamic IPs.
View 3 RepliesMy ISP provides two dynamic IP addresses. I have two computers that I want to each have a separate IP. I was told by the ISP, by two different CSR's, that I need a Desktop switch in addition to my Linksys WRT400 router. I purchased the D-Link 8-Port Gigabit Desktop switch and connected everything correctly. Although the internet works on both machines, they are still showing the same IP address. How do I allocate a separate dynamic IP to each machine?

View 15 Replies View RelatedI've got a new 891 to replace an old 837 and I'm struggling to get the dynamic nat pool working.I've successfully configured the dialer etc for PPPoE and when I set up a static NAT translation between my PC and an external address then I can ping hosts on the internet e.g. ping 8.8.8.8 successfully. But when I remove the static translation and try and use the dynamic NAT pool then no NAT translations take place, and show ip nat translations only shows the other static entries.The relevant bits of the config are below and I've also attached a full (cleaned) config.

View 13 Replies View RelatedOkay 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?

View 8 Replies View RelatedWe just purchased a company with multiple sites using Sonicwall's and Dynamic assigned external IP's. I am running a ASA 5510 with a outside Static.
I have done lots of S2S with both ends static but never a Dynamic to static.
what the commands are to set the ASA to accept dynamic VPN tunnels.
I am just CCNA, i have a project to configure site to site and remote access vpn on cisco 3000 routers and pix firewalls.. but the problem is only main site has the static ip while other sites have dynamic ips.
1- both the sides have dynamic ips.
2- one site have static and the other dynamic.
My SIP trunk provider uses a SonicWall Pro 3060, I need to initiate a IPSec VPN tunnel from an ASA 5505 (ASA1) for SIP traffic to a PBX connected on ASA1's inside.ASA1 should also connect a VPN to ASA2, ASA2 has a fixed IP I have not been able to figure out how to initiate the tunnel from the ASA1 to the Sonicwall due to the dynamic IP.
View 3 Replies View RelatedI have Remote Access VPN users (IPsec) who are terminated on Cisco ASA 5520 (v8.2). For those users, AAA is done on the ACS. Group-policies and tunnel groups are defined on ASA. Initialy I had all VPN users defined on ASA and group policies were associated with each user. Each group policy had it’s own IP pool for users. Now, I moved users to ACS. How can I associate group policy, defined on ASA, with users group defined on ACS? Is it possible that ACS send to ASA information about IP pool for different group policy? Users will use ONE vpn profile BUT based on the Active Directory group they belong to they obtain a different IP address for each group.Can it be done ? ACS version is 5.2.

Actually, the scenario was 1.1.1.1 is my LAN connection and 2.2.2.1 are my Wireless connection.
Overview Firewall is ASA 5510 running 8.4(9)Core network at Head Office uses OSPFStatic routes on ASA are redistributed into OSPFStatic routes on ASA for VPN are redistributed into OSPF with Metric of 130 so redistributed BGP routes are preferredCore network has a static route of 10.0.0.0/8 to Corporate WAN, which is redistributed into OSPFBranch Office WAN uses BGP - Routes are redistributed into OSPFThe routers at the Branch Office use VRRP for IP redundancy for the local clients default gateway.Primary Branch Office router will pass off VRRP IP to backup router when the WAN interface is downBackup BO router (.253) only contains a default route to internetUnder normal operation, traffic to/from BO uses Local Branch Office WANIf local BO WAN link fails, traffic to/from BO uses IPSec VPN across public internet I'm trying to configure dynamic routing on our network for when a branch office fails over to the IPsec VPN. What I would like to happen (not sure if it's possible) is for the ASA to advertise the subnet at the remote end of the VPN back into OSPF at the Head Office.
I've managed to get this to work using RRI, but for some reason the VPN stays up all the time when we're not in a failover scenario. This causes the ASA to add the remote subnet into it's routing table as a Static route, and not use the route advertised from OSPF from the core network. This prevents clients at the BO from accessing the Internet. If I remove the RRI setting on the VPN, the ASA learns the route to the subnet via the BO WAN - normal operation is resumed.I have configured the metric of the static routes that get redistributed into OSPF by the ASA to be higher than 110. This is so that the routes redistributed by BGP from the BO WAN into OSPF, are preferred. The idea being, that when the WAN link is available again, the routing changes automatically and the site fails back to the BO WAN.
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?

I have tried many different configurations on both sides, but they all fail with the same error of peer not authenticated by xauth.

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 am trying to configure a dynamic failover with IP SLA on a Cisco 7200 using 12.2(33) IOS. I would like to have something similar as the following configuration:

access-list 101 permit icmp any host X.X.X.X echo!route-map LOCAL_POL permit 10 match ip address 101 set ip next-hop Y.Y.Y.Y set interface Null0!ip local policy route-map LOCAL_POL

My questions are the following
Question 1: What is the equivalent of ip sla monitor in 12.3 for dynamic failover with IPsla Should I used
ip sla ethernet-monitor 1 type echo domain name ?
or
ip sla 1 path echo X.X.X.X or ethernet mpid echo domain name or icmp-echo time out 1000 frequency 3 threhsold 2
I do not know if I have to used ethernet-monitor or ip sla. What is the domain name and the mpid associated to the ethernet-monitor ip sla.In the case where I have to used ip sla 1, shoud I used a path-echo, ethernet mpdi or icmp-echo for dynamic failover
Question 2: In 12.3, what is the equivalent to ip sla monitor schedule 1 life forever start-time now.I have found thec command ip sla schedule 1 start now but it does not seems that we could configure the duration.
Question 3: Should I also enable ip sla responder
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 am prepping new ASA 5525-X's for a client that has multiple S2S VPN's. On some of the VPN connections, I need to do a policy nat to translate some of their subnets to a single IP address before it goes over the S2S VPN. However, when I try to use a subnet, I keep getting the following error:
Subnet cannot be used as mapped source in dynamic nat policy.
This works fine on their old ASA's which are running 8.2 code. I figured out I can use a network range, but cannot go over 65535 (or whatever it is) addresses in that range. This is very annoying when they have multiple networks they want to allow over the S2S VPN. Is there anyway around this or am I stuck creating a network range for each subnet?
am in the progess of replacing a Zyxel USG 300 to a Cisoa ASA 5510.In the Zyxel I have some Site to Site, where the peer is a dyndns.org adresse, becourse the peer is a dynamic ip-adress.
I have maybe 10 site to site´s where the peer is a dynamic with a dyndns.org adress, and the presharedkey is diffrent at each tunnel.How can i make this configuration at the ASA 5510?
I've got an 887M router which will be configured with two linke - one ADSL, one 3G - both of which will have (obviously) a separately suppplied IP address from the different ISP's being used. The 3G is a backup - plain and simple - for use only when the DSL service flakes out (which it does often)
Routing is pretty simple - I'll either do soemthing with a bit of PBR, or a simple weighted static, but the NAT has me scratching my head a little.
Can I have two outbound NAT pools (ip nat outside) for each interface which will be used ONLY for traffic going out the interface concerned?
For example, I have one for the primary link
ip nat inside source list 2 interface Dialer1 overload
Can I do the same for the second dialer interface like this
ip nat inside source list 2 interface Dialer2 overload
and have them automatically switch to using the dialer 2 IP for the outbound NAT if the dialer 1 link fails?
I don't think I've ever come across this before, so I'm not sure if it can even be done.
I have devices on Inside interface of ASA that need to get to Internet to get ntp. Hence I want to set up dynamic pat (interface overload) which 8.3 style would be
-object network obj_NTP-DEV
-host 192.168.1.250
-nat (INSIDE,INTERNET) dynamic interface
But I need to limit nat to only Internet destined traffic on ntp port not all ports for traffic from 192.168.1.250.I'm not using this nat set up to control outbound access - I also have incoming RA VPN tunnels to the box and traffic from these sources need to be able to get to 192.168.1.250 and the above simple set up would break that access as all traffic involving 192.168.1.250 would get nat'd
Reading the doco I've sent myself round in a loops trying to figure how you are meant to do such a " Dynamic Policy NAT (overload)" call it what you will config in 8.3
I have 2 computer connected and both have dynamic IPIf I change one of my computer's IP from dynamic to static Will it be okay to another comp ? ( Can it still connected to Internet / LAN )
