I have this situation, I need to establish an IP sec communication to another site but I need to identify all my packets sent, as a different networks as my local one. for example: my local network is 10.5.0.0/24 and I need to sent packets as 10.6.0.0/24. I suppose that I need to do Nat with this IPs. But in this router Nat is already applied to outbound traffic to Internet. How can I apply this NAT to crypto map only?
My router is a Cisco 877 with 12.4 IOS an this is the relevant configuration, crypto map vpn it´s used to sent traffic to second site.

I have applied a crypto map (fo ipsec vpn) on the dialer interface (for PPoE connection) in Cisco 2800; every time when the router restarts the crypto map is removed from the dialer interface even though i save the configuration every tim when i apply the map on the interface. Is there any way that the crypto map remains there on the dialer interface after the restart of router.

View 1 Replies View RelatedNew to the forum and not much Cisco IOS experience let alone on the security side of things. I know how to navigate the IOS and can do basic switching and routing just fine. My company currently has a DMVPN setup w/ about 10 tunnels going back to the hub. We have 4 more sites they want me to setup and I keep getting stuck at the crypto maps. I have been reading about VPN's, DMVPN's , etc. for days now but can't find any examples of how we are configured. The priority of our crypto maps start at 65536 and go up. Default max is 65335 from what I have read, and I cannot assign a priority that high statically. [code]

Just looking at a new clients setup and they have a ISAKMP vpn to the old security company I am trying to remove...I am fairly new to cisco, I actually know how to setup the ISAKMP policies, acl's etc but never had to completely remove one before All I can find is Clear Commands which seem to just flush the config not actually delete any of the policy etc...Its not that urgent as all passwords are changed on the domain and the cisco, the usernames have been deleted as well.

We have an HQ site with a 2811 (w/ADVSECURITYK9-M) acting as the firewall. We currently have 1 ASA5505 that has an established ipsec l2l VPN. I'm trying to connect a 2nd ASA, but I've noticed I can only add 1 cryptomap to the outside interface. A show ver shows 1 Virtual Private Network Module... Surely that doesn't mean only 1 VPN?Do I use one crypto map, and add a second 'set peer' & 'match address' inside the crypto map itself?

View 1 Replies View Relatedwe have a L2L-VPN-Tunnel beetween our Headquarter (ASA5520 with Network 10.100.1.0) and a branch office (Cisco1841 with network 10.100.10.0 ).

My question: How I have to change the crypto acl to reach this. Below the relevant parts of the branch route.
View 6 Replies View RelatedWe have 6 WAN routers connected through ISP MPLS cloud , we need to implement GET VPN between these WAN routers.We have 2 Key servers (1800 routers) , and the WAN routers will act as Group Members (6 GMs)
The attached configuration files are for working configuration for typical GETVPN (crypto map applied on WAN interface)
In Key server configuration , the crypto isakmp command is using the WAN interface IP address of each WAN router (172.16.x.x) , and since that the KS routers are connected to local backbone (VSS) , they should be able to reach 172.16.X.X , and therefore the subnet 172.16.X.X is advertised to the local network (check GM configuration file under eigrp - redist connected )
This is what our customer want to avoid ! they do not want 172.16.X.X to be advertised to the local network .I know It is possible in GETVPN configuration to configure ,the crypto isakmp command to use loopback address's of the WAN routers instead of the WAN IP , but in this case the crypto map must be applied to the loopback address , and this requires all traffic to be encrypted and decrypted to go through the loopback interfaces on all WAN routers .
i was wondering what is the best solution for this case , I though to use the below config on the GM's
We run a hub&spoke network with dual GRE tunnels from each spoke site to seperate independant adsl routers at the hub.IPsec is enabled on each tunnel with crypto maps and then QOS is enabled with pre-classify for voice traffic priority. We also have defined a class for Citrix traffic by identifying port1494 traffic out and anything bound for our citrix servers IPs.Ok so the problem is that once the encryption comes up on the tunnels, the citrix programs wont connect. Take the crypto map off the tunnel and all works fine.
Here is the relevant config
crypto isakmp policy 1 encr 3des authentication pre-share group 2crypto isakmp key **** address *.*.*.*
crypto isakmp key **** address *.*.*.*
crypto map SDM_CMAP_1 1 ipsec-isakmp description Tunnel to hub1

set transform-set ESP-3DES-SHA match address 104 qos pre-classifycrypto map SDM_CMAP_1 2 ipsec-isakmp description Tunnel to hub2
set peer *.*.*.*
set transform-set ESP-3DES-SHA match address 105 qos pre-classify

I deliberately weight EIGRP to favour Tun0 and have Tun1 as a failover. I was thinking of Route-mapping the Citrix traffic to Tun1?
I have ASA5540 with asa712-k8.bin.

I have setup ipsec VPN in my C2811 router but when "show crypto isakmp/ipsec sa" shows nothing. Remote end point is an "ASA5520". Does it indicates that the remote ASA5520 not yet configured?
Code...
My router is Cisco 2811 with IOS version 12.4(22)T1. It had established IPSec with another peer (203.*.*.250 shown below) for long until recently we make it re-establish IPSec VPN with another peer (203.*.*.30 shown below). It showed that the new sa is active but the result still showed there were 4 deleted SAs. The 4 obsolete sa entries won't vanish no matter what I do i.e. reset the interface, re-create crypto map, clear all sa and etc.
From numerous testings we knew that the VPN doesn't work even the desired sa is there remaining active. I reckon it has something to do with those deleted sas ( i mean it is supposed to show only the last one if it is working fine ). I don't know how it would be come like this as we did pretty much the samething on other VPN routers with no problems.
I am trying to set up vpn tunnel between ASA and router C2921 for site-to-site routing. This was described on many sites. However I do not have required option under crypto command.
g1c1router1(config)#crypto ? key Long term key operations pki Public Key components
g1c1router1(config)#crypto
There are no crypto map etc options.
Some people suggested that I need crypto IOS. I have:
boot system flash:c2900-universalk9-mz.SPA.152-4.M3.bin
license udi pid CISCO2921/K9 sn FGL171910C1
Do I have to generate some keys? How do I do it? crypto key generate ?
ASA is the server, 2651 is the client. Phase 1 is negotiating, after entering XAUTH on the 2651, the ASA is showing:
Rejecting IPSec tunnel: no matching crypto map entry for remote proxy 10.250.2.0/255.255.255.0/0/0 local proxy 10.10.3.0/255.255.255.0/0/0 on interface Outside
Not sure what this means in this instance, the maps are setup the same as the article below. I guess I more expected that sort of error if this was a static tunnel and there was an ACL issue. I don't have a lot of knowledge on the Easy VPN with the ASA. [code]
