Cisco VPN :: Creating GRE Tunnel Over ADSL Between ASA 5510 And 2901 Router?

Jul 6, 2011

I've been looking to see if its possible to create a GRE tunnel between a Cisco 2901 with 3 adsl WIC cards and a Cisco ASA.The Cisco 2901 is at our remote office and we have 3 adsl lines for resillience as they tend to go down alot.The Cisco ASA is at our Head Office sitting behind our ISP's managed router.
 
The desired end result would be to have three GRE tunnels, 1 for each DSL line terminating on the ASA at head office and use EIGRP routing protocol to move traffic across to another tunnel should one fail, and encapsulate all of that with IPSEC.

Cisco :: ACLs To Limit Ports With Client - Based VPN Tunnel

Jun 16, 2011

I have a customer I've built a webvpn tunnel for.Users on this tunnel need to have http access to a server at 10.1.1.12 and nothing else.That's fine, but in order for name resolution to work properly they need to be able to send DNS requests to 10.1.1.9.I'm working with two different access lists, my non access list (nat 0) and my split tunnel access list. I can't specify ports in the nat 0 access list, but I did try writing my split tunnel access list as follows:

-access-list split permit ip host 10.1.1.12 172.16.4.0 255.255.255.0
-access-list split permit udp host 10.1.1.9 eq 53 172.16.4.0 255.255.255.0

When I do that users can access the 10.1.1.9 dns server, but they can hit it on anything (ping, 3389, etc.).I'm trying to figure out how I can limit them so they will only be able to pull dns but nothing else.They have the Any connect Essentials license, so unfortunately a clientless VPN is not an option. Is there some other access list I can interpose that will limit things the way I want?

Cisco VPN :: 2901 / 2951 - Site-to-Site VPN - Constant DPD - Tunnel Drops

Dec 12, 2012

We have approx 40 branch offices - all of which are connected to a single core site over VPN Tunnels using various gear. At one particular site, we are having issues with the tunnel dropping sporadically throughout the day - some days it happens 10 times, some days it happens none. This just randomly started happening two weeks ago, without any changes taking place. Since it started happening, I have upgraded the code to latest versions, but still the issue persists. This particular site has a 2901 and connects back to a 2951.

Cisco VPN :: 886 DMVPN Tunnel Sourced Via Loop Back Error

Nov 22, 2012

I am having a hard time trying to configure DMVPN with the tunnel being sourced via a loopback interface. All routers are Cisco 886 routers which don't have L3 ports.That is why I used SVI interfaces, and have configured the L2 ports (Fa0, Fa1, etc.) with the command switchport access vlan.The problem is that I am receiving Invalid SPI error's only on the Hub router and I have no clue what could be the problem, because they use exactly the same parameters for IPsec.

Cisco :: DMVPN With OSPF Area Router Limit And Per-area Limit?

Oct 31, 2012

need to know the OSPF best design. I have a customer currently running their OSPF only in two area. Area 0 is provider reside and area 1 reside 700 hundred over of router including HQ router and remote branch router connecting to metro-E 10Mbps networks. Is this design have any weakness? Area 1 about 800 hundred router reside in, the HQ model is cisco router 7200 and remote end is cisco router 1841.Let's say they want a solution, for 3G remote router connect back to the HQ using Lease line with a fixed IP. Using DMVPN and OSPF communicating back to HQ. What should we aware when designing and implementing for the OSPF best practice. They have 700 hundred over remote branch need to terminate back to their HQ. I read cisco recommend an area should not be more than 50 router and per-area no more than 28 area.

Cisco VPN :: 2901 - VPN Between IOS And ASA Only Working 1 Way

Jun 9, 2013

I have a Cisco ASA and a 2901 Cisco Router connected via site-to-site VPN. The ASA can ping over the VPN to computers behind the router, but the router can not always ping to computers in the ASA network. When i ping from a computer in the IOS router's 10.100.36.0 network the requests times out most the time; although every few minutes, i will get about 10 pings back, then stops working again. 

I uploaded their two configurations.

The ASAs public IP is 20.20.20.5 and local (inside) network of 10.101.36.0/24
The IOS routers public IP is 20.20.20.10

There are many internal networks, but 10.100.36.0/24 is the one with issues.

Cisco WAN :: Internet Connectivity On 2901 ISR

Jan 1, 2012

Physical devices are a Cisco 2901 (CISCO2901/K9)  with GE0/0 configured as 192.168.1.1
Connected through a D-Link DGS-1210-24 configured as 192.168.1.202
Running on a domain with an HP domain server as 192.168.1.2
 
The 2901 was an EHWIC (VA-DSL-A oPoTS) on EHWIC 0/0/0
GE 0/0 on the 2901 is physically connected to the DGS-1210 which is physically connected to the server.
VDSL 0/0/0 is physically connected to the DSL jack.
 
So far the configuration reports all is connected, and I can ping the gateway of our ISP (using CLI or Cisco CP); however the server reports no internet connection and no workstations can access the 'net.
 
Once connected; I'd also like to allow ports through for use on the network (25, 80, 110, 443, 987, 1723) - but not sure on how to do that just yet!

Our IP is 202.27.19x.19x
Our Gateway is 202.27.217.5

Cisco WAN :: 2901 Link To Vendors / How Would You Set It Up

Oct 4, 2011

I have inherited a setup for a custom application and would like to know if this is the only way this could be set up.  How would you do it?The application uses dedicated T1 links to our vendors.  There is a Cisco 2901 router in the middle providing the connections.  Traffic to specific vendor's IP's are routed to their prospective connections.  I have attached a network diagram and a config for the 2901.  The way my predecessor(s) set this up, each different vendor uses a different private IP address for the  internal links.  This seems odd to me.  Shouldn't there be a way to have only one subnet on the inside and have the links NAT depending on which route it takes?  The servers have persistent routes built in them to send vendor traffic to the associated IP on the router.  E.g., traffic to Vendor 1 is routed to 192.168.50.1, the 2901's IP address for the Vendor 1 network.  That traffic is then NAT'd to  an IP address associated with Vendor 1's link and the 2901 then routes the traffic to the Vendor's end of the link.
 
I would think that I should be able to revamp this so that internally we're only using one subnet and the traffic could NAT at the link associated with the Vendor.  I recently had to add the 3rd vendor connection, and wound up having to duplicate what was done for the other two in order to get it working quickly.  I didn't have the time to wrap my head around the best way to revamp the whole thing.

Cisco VPN :: PPTP Disappeared On 2901?

Jul 6, 2012

I recently obtained a 2901 router running 15.2(2)T to replace my old 877 which was running 15.1(4)M1. The 2901 is humming along quite nicely but I have had difficulty configuring one feature which was working fine on the 877. The router needs to be a PPTP client to a hosted VPN service. On the 877, I had it configured like this: [code] I then had a dialer interface to actually set up the connection, and some PBR to control what went over the VPN. All well and good, and it worked fine. But on the 2901, when I try to configure the same thing, there is no such command as "protocol pptp" -- the only option is protocol l2tp.Was PPTP support deprecated somwhere between 15.1 and 15.2, or does the 2901 itself not support it for some reason? Obviously I understand that l2tp is superior to pptp, but at the moment this is my only option.

Cisco VPN :: GETVPN KS Placement With 2901

Jul 2, 2012

Where's the ideal place to put the KS? My current setup is 1 KS, 19 GM. The KS sits BEHIND a GM, so all other GMs have to come through one GM to get to KS.Now, I have purchased two dedicated KS routers. I configured one today, and placed it right on my WAN. My WAN is a L2 Ethernet domain, so i just provisioned a switch port in the WAN vlan, and away we go. I copied RSA keys over from the current KS, configured redundancy and the two hooked up, saw each other and it seems to be good to go. For the ACL, I put in an exclustion for my two KS to talk to each other:

deny ip host 192.168.250.40 host 192.168.250.41 (Old IP, New IP)
deny ip host 192.168.250.41 host 192.168.250.40.
 
I used a test router and pointed it to the new KS, it registered without a hitch... HOWEVER about two hours later (my 7200 second timeout) I lost ALL my branches. My 18 other GM were still pointed to the OLD IP only, they didnt have the second IP configured yet. In a hurry, I quickly disabled the redundancy configuration on the old KS and had to go to each GM and do a 'clear crypto gdoi' on each one to get them to re-register. There were no log messages about not being able to rekey, no log messages about dropped peerings, nothing. Once I did that, everything returned to normal.
 
The Question I have...
Would having configured the redundant KS caused this problem? Would having one KS behind a GM and the other Coop KS in the WAN make a difference?

Relevant config from existing KS, 2801:
crypto gdoi group GETVPN_GROUP
identity number 1234
server local
  rekey retransmit 60 number 2
  rekey authentication mypubkey rsa GETVPN_KEYS
[Code]...
