We want to use cisco 3845 and pick up IPSec, with remote side. But I am afraid that cisco 3845 can't handle 155 Mbits over IPsec. We will buy AIM- VPN/ SSL3 card. Is this sufficient?

View 3 Replies View RelatedAs shown in the diagram below, I have a central office and two branch offices, these offices are connected by a private routing service that has no connection to the Internet, the telecommunications operator in each office installs a router with a LAN and a WAN IP and configuration of these devices cannot be changed except the LAN IP. Only the central office network that is 192.168.0.0 have a router that has internet access. Remote offices have no access to the internet, what is needed is that remote offices can access the internet using ADSL router 192.168.0.254 at the central office. There are a small devices in each remote office that must connect to the internet and do not support any configuration except IP, mask and gateway, for example you cannot add a static route. Currently the pcs at remote offices has IP communication with the server from the central office using a static route.Does the solution would be to put some VPN routers between each LAN and the operator's routers (where RT yellow star appears in the diagram) and put the hosts of the two branch offices same IP range that the central office network?

View 6 Replies View RelatedWe have two ASA 5500 series Firewalls running 8.4(1). One in New York, another in Atlanta.They are configured identically for simple IPSecV1 remote access for clients. Authentication is performed by an Radius server local to each site.
There are multiple IPSec Site-to-Site tunnels on these ASA's as well but those are not affected by the issues we're having.First, let me start with the famous last words, NOTHING WAS CHANGED.
All of a sudden, we were getting reports of remote users to the Atlanta ASA timing out when trying to bring up the tunnel. They would get prompted for their ID/Password, then nothing until it times out.Sames users going to the NY ASA are fine.After extensive troubleshooting, here is what I've discovered. Remote clients will authenticate fine to the Atlanta Firewall ONLY IF THEY ARE USING A WIRED CONNECTION.
If they are using the wireless adapter for their client machine, they will get stuck trying to login to Atlanta.These same clients will get into the New York ASA with no problems using wired or wireless connections.Windows 7 clients use the Shrewsoft VPN client and Mac clients use the Cisco VPN client. They BOTH BEHAVE the same way and fail to connect to the Atlanta ASA if they use their wireless adapter to initiate the connection.
Using myself as an example.
1. On my home Win 7 laptop using wireless, I can connect to the NY ASA with no issues.
2. The same creditials USED to work for Atlanta as well but have now stopped working. I get stuck until it times out.
3. I run a wire from my laptop to the FiOS router, then try again using the same credentials to Atlanta and I get RIGHT IN.
This makes absolutely no sense to me. Why would the far end of the cloud care if I have a wired or wireless network adapter? I should just be an IP address right? Again, this is beyond my scope of knowledge.We've rebuilt and moved the Radius server to another host in Atlanta in our attempts to troubleshoot to no avail. We've also rebooted the Atlanta Firewall and nothing changed.
We've tried all sorts of remote client combinations. Wireless Internet access points from different carriers (Clear, Verizon, Sprint) all exhibit the same behavior. Once I plug the laptops into a wired connection, BAM, they work connecting to Atlanta. The New York ASA is fine for wired and wireless connections. Same with some other remote office locations that we have.
Below I've detailed the syslog sequence on the Atlanta ASA for both a working wired remote connection and a failed wireless connection. At first we thought the AAA/Radius server was rejecting us but is shows the same reject message for the working connection. Again, both MAC and Windows clients show the same sequence.Where the connection fails is the "IKE Phase 1" process.

I'm trying to set up an IPSec tunnel between 2 3845 routers that each sit in a private LAN behind an ADSL modem. Each modem does have a static public IP address from the ISP.
Thus:
Cisco 3845-1 <-> ADSL modem <-> WAN <-> ADSL modem <-> Cisco 3845-2
3845-1
Gi 0/0 - private ip
l
NAT
[code]....
So I would like to set up IPSEC between the GI 0/0 interfaces on the 3845's.
To configure the GRE tunnel over IPSEC with OSFT via Encryption module from Cisco Router 3845, I have few queries:
1. Does the router 3845 support hot swap for encryption module?
2. Does the router require to be rebooted after plug in encryption module?
3. Any samples configuration for GRE tunnel over IPSEC?
How to reconcile what I've observed on our routers on a tunnel interface. The maximum amount of data I can get across the tunnel is 1339 bytes, which seems just a little bit too small. Background: we have two 3845 routers with IOS 12.4(3a) advanced ip services. I have tunnel interfaces on both routers, interface configs are below.
crypto ipsec transform-set MY_TSET esp-3des esp-sha-hmac comp-lzs crypto ipsec profile MY_VTIset transform-set MY_TSET
[ Code]..
When I test the mtu of the source destination interfaces I get 1500 bytes, as you would expect from an Ethernet connection to a service providers MPLS network. See output below:
Router1#ping ip 10.252.0.18 df-bit size 1500
[Code]...
When I test the mtu of the tunnels I get 1339 bytes, see the output below.
router1#ping ip 10.1.40.133 df-bit size 1340
Type escape sequence to abort.Sending 5, 1340-byte ICMP Echos to 10.1.40.133, timeout is 2 seconds:Packet sent with the DF bit setM.M.MSuccess rate is 0 percent (0/5)
[Code]...
That comes to a total of 1420, which is 80 bytes short of the mtu of the source/destination interface of the tunnel.
I am just setting up a simple scenario with a 1841. Server @ 172.31.1.1 cannot ping 172.31.0.254 or 172.31.0.105. It can ping 172.31.1.250. The router can, on the other hand, ping devices on both networks. This is just for testing routing theory so I don't know why hosts on either side of the network cannot ping each other.
I am only using the FastEthernet interfaces on Router 1841.

View 4 Replies View RelatedI'm trying to setup an ASA and a UC540 side by side, to utilize the ASA for data networking and the UC540 for voice. This 'should' work fine, I just seem to be having an issue where the ASA seems to be blocking traffic from the voice network as it passes through.So here is the LAN setup:ASA: 1.1.1.1UC540: 1.1.1.2The UC has a voice vlan 10.1.1.1/24 and a service module at 10.1.10.1/30My PC uses the ASA as its default gateway, 1.1.1.1The ASA then has static routes to the UC networksRoute 10.1.1.1/24 1.1.1.2Route 10.1.10.1/30 1.1.1.2Ping from PC to the UC networks works fine. However, ping from the UC networks to PC fails. ASA logs show traffic being denied due to not having an established connection or something.My guess is that the traffic is being blocked because the egress and ingress paths are different? Traffic from the PC goes to the ASA, then gets routed to the UC and it works. However in the other direction, traffic from the UC is going directly to the PC and bypassing the ASA, because its a directly connected network and doesn't have to route through the ASA to get to the PC. The reply traffic from the PC DOES go through the ASA following its route table, thus the issue of the ASA not seeing the established connection?Same-security inter and intra interface is enabled.So I think I see the issue, I just don't know how to fix it. Is there something I can configure on the ASA to allow for this? My only other option would be to configure a /30 on a new vlan to handle the routing between the UC and ASA or something, but that seems like its going to make this simple setup way too complicated with extra networks, vlans, trunks, etc.I am running ASA version 8.4.5?

View 3 Replies View RelatedWe are trying to add an additional LAN-to-LAN IPsec VPN to our network. We currently have one remote office connected, when we configure the second VPN matching the first the tunnel never begins to establish. There is an ACL that is dening the static IP for our remote office.
The layout is as follows:
Main office = ASA 5520
Remote Office A = ASA (Unknown Model)
Remote Office B = Adtran Router
All devices have static IP addresses.
We used the ASDM VPN wizard to create both VPN's.
We have created a rule allowing all traffic from our remote office IP, and that had no effect on the VPN aside from eliminating the following message from our logging:
4 Mar 19 2012 15:18:01 106023 67.50.19.230 50234 TWT-hq-e 31326 Deny udp src TWT-outside:67.50.19.230/50234 dst inside:TWT-hq-e/31326 by access-group "outside-in" [0x0, 0x0]
We have verified that both sides are configured the same however the VPN never is initiated so as of right now the ASA is simply blocking all attempts from our remote office to connect.
how can you configure remote vpn ipsec tunnel on a Cisco 800 router?
View 12 Replies View RelatedI've been using an ASA 5505 -- ASA 9.1(1) -- with an IPSec Remote Access VPN. Everything works properly, though I recently noticed that when my IPSec session is disconnected, I get the standard message ID 113019, but within that message the Peer IP address is incorrect. In fact, it isn't even close to my actual remote address. [code]
When I first researched the IP, I found it coming from China, which freaked me out. I changed settings, rolled back to 9.0(1), and nothing worked. Finally I rebooted, reconnected the VPN, and the IP changed. This time it was an address from RIPE NIC. I rebooted again, now an address from ARIN in the USA. One more reboot, now a random Comcast residential address.
Within that boot cycle, the peer address always stays the same. I've connected from different devices, different IPs, different ISPs - nothing matters. Additionally, there are no firewall logs for these IP addresses at all.
ASA Remote Access VPN peer addresses in disconnect message are incorrect and change at reboot.
Is there any documents that I can use to design an IPSEC remote access solution using 2 data centers . One data center is primary and other one is secondary. The VPN is terminated in ASA 5520. End users using cisco client.
View 6 Replies View RelatedWe already have IPSEC VPN connectivity established between sites but would like to introduce some resilience/redundancy at a remote site.
Site A has an ASA with one internet circuit.
Site B has a Cisco 2911 with one internet circuit and we have established site-to-site IPSEC VPN connectivity between the 2911 and the ASA.
Prior to getting the new internet circuit, Site B had a Cisco 877 with an ADSL line which are still available but aren’t currently in use.
The internet circuit at Site B has dropped a few times recently so we would like to make use of the ADSL circuit (and potentially the 877 router too) as a backup.
We thought about running HSRP between the 877 and 2911 routers at Site B and, in the event of a failure of the router or internet circuit, traffic would failover to the 877 and ADSL.
However, how would Site A detect the failure? Can we simply rely on Dead Peer Detection and list the public IP address of the internet circuit at Site B first with the public IP address used on the ADSL line second in the list on the ASA? What would happen in a failover scenario and, just as important, when service was restored – I’m not sure DPD would handle that aspect correctly?
I’ve read briefly elsewhere that GRE might be best to use in this scenario – but I can’t use GRE on the ASA. I have an L3 switch behind the ASA which I may be able to make use of? But I don’t want to disrupt the existing IPSEC VPN connectivity already established between the ASA and the 2911. Can I keep IPSEC between the ASA and 2911 but then run GRE between the L3 switch and the 2911? If so, how would this best be achieved? And how could I also introduce the 877 and ADSL line into things to achieve the neccessary redundancy?
I have configured ASA 5510 With IPsec Remote VPN.With local database users(Users are created in ASA).
Internal network has 4 VLANS. Need solution for below.

Is it possible to configure Group policy in ASA for IPsec Remote VPN.
I have a site-to-site VPN configured between a 5520 at our data center, and a 1700 at a client's site for site-to-site connectivity. What I've noticed is, is that the VPN can only initiate from my Data Center, never from the client router. I can telnet into the router and start a telnet session sourced from the "inside" interface and it fails, yet I can see the NAT translations get created in the state table that should match the crypto-map. However, if I ping a host on the inside of the remote LAN from my workstation (behind the 5520) to bring the tunnel up, and run the exact same command on the client router once the tunnel is up, it works. Right now I have a continuous ping running from my workstation to keep the tunnel up, but obviously that's not the best solution
I had to modify this config to NAT the LAN addresses at the client to a non-overlapping subnet, so anything coming from 128.1.0.0/16 should be NAT'd to 192.168.105.[50-200]/24. I've also got two static NATs for inbound access from the data center and those seem to work fine.
