New 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]
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'm trying to get several VPN tunnels up. It seems that only 1 map can be assigned to the WAN interface (fa4). Is this true or is there an 'extended' map like ACLs?
I have to connect one of our it labors with some ec2 instances in amazon vpc. I downloaded a configuration file from amazon which starts with the command
crypto isakmp policy 200
My router tells me that he does not know crypto isakmp.
I searched on the internet and found that i have to install a specific license, but unfortunately i cannot find which license i have to install.
The show license command show following licenses
AdvIpServices active AdvSecurity active advsecurity_npe, ios-ips-update, waas_Express no state displayed ssl_vpn active but eula not accepted
I found that i can accept the eula license with license boot module c880-data technology-package SSL_VPN command
But this command is also not available on my device. getting the crypto isakmp command working?
i have Cisco 1941 router with following IOS image:Cisco IOS Software, C1900 Software (C1900-UNIVERSALK9-M), Version 15.0(1)M5, RELEASE SOFTWARE (fc2) below mentioned commands are not working :
I have a Cisco 881 ISR (CISCO881-SEC-K9) and have the advanced security license installed and enabled/active and in use (see screenshot). However, the isakmp crypto module is not available.
There use to be Cisco 851 routers, but lately these routers are replaced with Cisco 861-K9 routers, and these 861 routers doesn't support DMVPN, instead 851 use to be.
Is there any license file we can upload in 861 router for DMVPN capability, if yes may i know the SKU # for that. We have some customers having 6-7 locations and they are planning to have 2 more locations, we implement already DMVPN in there network, if we go with the 87X or 88X router there price is almost double the price of 861.
I just wonder if there is simply way on Cisco 800 to set bandwidth priority for internal IP address. Basically I have server and would like to make sure, whatever comes to it or goes out has the highest priority and users won’t kill bandwidth for the server connection.
I am fairly new to Cisco, but am trying to configure a 1921 router to give higher priority to SIP/VoIP traffic (Port 5060) than everything else.The connection is only 4Mb and is getting hit hard by video streaming, I don't want to block this, just make a lower priority.Any ideas where I am going wrong?My current config is as below.The IP addresses have been changed for security reasons, but in reality are both in the same range, i.e. are both external IPs, so I am not sure if this is causing the problem. Do I need NAT for QoS to work?
1)How or where i could read about access point join WLC controller in multicontroller network?
2)Is it possible and if yes how i could made such scenario: I've got existing netwirk with two wlc 4402, i want to join third wlc 5508 and new access points, but i need that new access point joins to wlc 5508 first,and if all licenses used,jins to wlc 4402 second. Or where i could read about it?
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.
In a basic VPN l2l scenario using ezVPN, server behind NAT device, client using 3G. What would be the reason to have in the output of the show crypto ipsec sa, a current peer different from remote crypto endpoint on the server ?
In my test lab , I have a CISCO 1841 with a AIM-VPN/BPII-PLUS board , everything was working fine , until I would like to see the difference with and without the accelerator.Sins the moment that the IOS told me that he will change to SW accelerator instead of HW accelerator , I can not make it work anymore.I have a copy of the full working configuration before I did this , I have put it back on my router but still NO VPN. [code]
I am trying to configure Crypto PKI in ciscio 2911, Once i configured the root certificate for the router , i can see the validity date wrongly but the same certificate is fine in the other devices . [code]e when i am trying to configure the local certificate.
I have a ASA 5510 that has something weird going on I have just added a base config where you can access on a inside interface but for some strange reason after I disconnect i have to ping inside interface first before I can connect via telnet or SSH and then regenerate therecrypto key
I ahve a requirement to configure static crypto for 1800 site and I need to configure on two sepaarte interfacs at spoke site which means I need to configure 1800*2 = 3600 peers at central site. The challenge I have is due to load balancing , the traffic dynamic crypto can not be used since traffic may be initiated from Dc on other link which may get dropped incase not encrypted.
I have just received a new cisco 2901 and started on its configuration. when I started configuring VPN tunnels, I saw that non of the crypto commands are available.
The router runs on iOS 15.1.From what I read, people refer that the router needs to past a license activation or something like that. When I run show verison - i do see "none" under most of the categories.
I have a problem with my routers (cisco 1941)I'm running a DMVPN network (Hub and spoke)All the hubs are connected to the 2 hubs. With 4 tunnels. (each hub has 2 interfaces to the spokes. the spokes only have one interface to the hubs, so I splitted them and so I now have 4 dmvpn tunnels). one of the interfaces on a hub malfuntioned and because of that the customers had problems with logging in and sending packets. I made this kind of structure because of when one of the tunnels failed the spoke could use the 3 others... BUT, what happened here was that the spoke still tried to use all 4 of the tunnels and because of that I had 25% package loss!So this didn't work. Now I read about IP SLA, but I was wondering of this could work? (I cannot test it on spare routers, and I don't want to implement it and risking a total network failure...) and how to configure it. Should I make 4 different sla processes which I should all 4 track? And when I make the ip routes, how should I make or configure it so that 1 of the tunnels/interfaces fails that the spoke would addapt the routes?
I have a setup with two Cisco 877's – 1 for the hub and 1 for the spoke. The hub has a static WAN IP and the spoke has a dynamic WAN IP. The two sites are tunneled with DMVPN and cert auth for connections via Cisco VPN Client (terminating on hub router). All routes between the two sites work fine – I can see through both ends via LAN IPs and tunnel IPs. I can connect externally through Cisco VPN Client and RDP into PC's on the spoke end via local IPs.
My issue is: I want a port forward on the hub router, pointing to the IP (172.16.1.X) of a device on the spoke end. So using the WAN IP of the hub router, I can reach a host on the spoke side. At this point I cannot get this to work and feel it's related to a NATing issue. Here is my current config for both sites:
I have a DMVPN network with 2 hubs (2821's). This setup is used for VoIP applications over the Internet for teleworkers. At the main hub site I used to have only 1 Internet feed which was DSL with a static IP. Now I have 2 WAN feeds for this site - 1 FTTB w/ PPPoE & the DSL with static IP. Since this site also hosts a PRI, I want all voice communications to go through the FTTB link instead of the DSL for obvious reasons, but keep the DSL as DMVPN Hub for all NHRP lookups as this link has a static IP address & is very stable. We originally put the PRI router as a DMVPN spoke which connected through the FTTB link, with another router acting as the DMVPN hub on the DSL link. This was obviously a waste of machinery. I want to combine both routers into one. So I tried something like this (don't laugh):
Gi0/0 to FTTB (Dialer1 connects to Internet) Gi0/1 to DSL (Public IP towards 877 demarc) Tun0 attaches to Dialer1 public IP and connects to other spokes, no VRF Tun1 attaches to Gi0/1 public IP and acts as DMVPN hub (ip nhrp map multicast dynamic) under VRF "Hub"
EIGRP AS 1 is set up twice, once under router eigrp 1, and the other using router eigrp 2 using an address-family under the Hub VRF.This kinda works but obviously Tun0 & Tun1 do not speak to each other. I also had to remove the ip nhrp map instruction that pointed to Hub1 on Tun0, as this was causing a weird condition in the router where it was repeatedly trying to connect a tunnel to itself, and crash the router because the NHRP process would go haywire. So my users must rely on the Hub2 to get a NHRP lookup for the PRI site. If Hub2 goes down, everything works in the network except for tunnel connections to the FTTB link. I'd rather not have to configure 2 tunnels on each spoke router unless I really have to.
When I ping my video streaming host's IP address (the IP that they gave me where I can view my IP web camera's video stream), I get anywhere from 0% to 8% packet loss at various times of the day. They're claiming that there's no problem, that this is because this is a router and it's dropping ping packets due to "ping priority giving preference to more important network traffic."
I've got a LAN with private IPs for the computers, and public, static IPs for the VoIP phones. They are a Hosted VoIP provider, and I want to give priority to the public IPs with my ESW-520-48P switch. How do I implement that in this switch?
I have no roles assigned on the ports and no VLANs setup either. I had tried segregating the VLANs first, but eliminated that route. It's all VLAN 1 now in the switch again. For some reason when I implemented VLAN 100 for voice, voice stopped working on the phones, but data was still fine.
I have a known working configuration with many sites and one operative center that receives all communications.The connection OF THE OLD SITE is here detailed:Now I need to integrate another site. The difference between the old site and the new site is the following:
-old site communicates with the operative center by means of the FE0/1 or by means of an HWIC4T serial interface. old site automatically switches between the tunnel on the ethernet interface (FE0/1) and the serial channel giving priority to the ethernet tunnel. -new site will communicate with the operative center by means of the FE0/1 or by means of a transceiver device connected on the FE0/0. -both new site and old site have a LAN on the FE0/0 where data is generated and sent to the router to be dispached to the best available channel.
The connection of THE NEW SITE is here detailed: the old site was configured this way: [code]
the first line means that everything starting from the client directed to 192.169.0.2 it will be sent on the tunnel1.the second line tries to route the same packets on serial0/0/0 with low priority.On the New site i did the same:
i created the tunnel form my cisco 2811 to the operative center using the FE0/1, then i added the following:ip route 192.169.0.2 255.255.255.255 Tunnel1
This works as expected routing the packets to the operative center on the FE0/1.Now I miss the second part: route packets on the FE0/0 to the ip address 192.168.1.31 WITH LOW PRIORITY like i did on the old site.
I did some tries but no one solves. Which is, in your opinion, the right command to add on the cisco2811 in order to get the equivalent of what i did on the old site ( ip route 192.169.0.2 255.255.255.255 Serial0/0/0 10 ) ?
Our company had been buying Cisco 1841 routers for years and they have served us well. The 1841 was discontinued and instead we have now purchased a Cisco 1921. It is brand new, running "Version 15.0(1r)M15" of IOS ("usbflash0:c1900-universalk9-mz.SPA.151-4.M4.bin" file).
On our older Cisco 1841 routers, we would always prioritize certain TCP and UDP packets using the priority-list command. However, I have suddenly discovered that priority-list is not available on this brand new router. (?) I am unsure why. I did some reading and according to the document [URL], and priority-group are unsupported in Cisco IOS 15.
Later version of a product isn't as fully-featured as the earlier version. I want to prioritize the following type of network traffic.
UDP ports 8000 through 8063, 2427, 2727, 9300, 9301 TCP port 35300, 60001 through 60010, 2065, 33333, 3065
giving them a higher priority than the rest of other packets. This is necessary for our vendor's VoIP implementation. These packets should be "high" priority; everything else can be "medium."
I have a cisco 887 connected as temp measure to a 3g device via a fast0 port. all works fine. VPN comes up...but the moment i apply the crypto map to the vlan.. DHCP stops allocating ip address. I have remove irrelevant config ( dialer, atm etc as they not been used)
config below p dhcp excluded-address 10.29.80.253 10.29.80.254 ip dhcp excluded-address 10.29.80.1 10.29.80.229 !
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.
#show crypto isakmp peers Peer: ** Port: 500 Local: ** Phase1 id: ** #show crypto isakmp policy Global IKE policy
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?
I replaced old cisco router 2811 with new one 2921 , all works except crypto map VPNs routers can ping each other , ACLs are not applied to outbound interfaces show crypto isakmp sa is empty after i make same configuration on a new router 2921 config.
we 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 ). This works fine for years, but now we wish to change the configuration so that ALL traffic from the branch office goes over the vpn-tunnel. My question: How I have to change the crypto acl to reach this. Below the relevant parts of the branch route.
